Bright Box faulty or just pants?

Is my Bright Box faulty or just plain rubbish?

I recently switched from BT to Orange in February to save money on my broadband/phone deal. I was sent the new Orange Bright Box router when I joined. I replaced my BT HUB2 with the Bright Box, using the same cabling and filtered faceplate I had previously used and it synced at a slightly higher speed of 6368Kbps than the HUB2 did (the HUB2 had settled at 5920Kbps). The exchange is 20CN 8Mb ADSL only. I'm 1km from the exchange as the crow flies across a public park, 2km by road.

It spent the next week going up and down through the sync ranges and attempting to connect at some very high speeds. Eventually though it settle at the same speed the HUB2 had been using previously. Great, and I had a good many weeks of trouble free surfing through March. Well mostly, at one point we had no connection and Windows7 troubleshooter reported that the DNS server was not responding. I logged into the Bright Box and there did not seem to be any problem, it said it was connected. So I used the reboot option and when it reset it worked fine, I could browse the web again.

The DNS problem occurred again at the beginning of April. Thinking Orange may have a problem I manually put in the IP's of a couple of public DNS servers, but it did not work there was no connection even though the router again said it was connected. I rebooted the Bright Box and again it worked, I could browse the internet again. I then started to notice that MS Messenger would keep disconnecting. I had connection issues with Messenger in the past and an MS KB article recommended changing some TCP/IP settings in Win7 which had solved it. As Win7 establishes a new connection with fresh TCP/IP settings for each new network connection, I simply thought it was the old problem resurfacing because I had not altered the new TCP/IP settings. However, I eventually noticed that the Bright Box was re-syncing at the same time.

Then the broadband light started flashing (slowly) every time I tried to go on the internet. It was rock solid until I tried to open a web page or log in to another online service like Messenger, email, etc. It would take an age to re-sync and would only stay connected for a minute or two while I browsed, before doing it again. If it re-synced too high (one time it got to 7456kbps) Win7 would again report the DNS server was not responding. One day the wife tried to log in using Wi-Fi and it disconnected again. I got a call at work and she said that the broadband light was flashing again, it was still flashing when I came home 3 hours later. I simply switched it off, waited and turned it on again. Guess what it worked again.

I tried it in the test socket to rule out the faceplate filter and it still disconnected. At this point I was thinking the Bright Box had gone faulty. I dug out my old Netgear DG834v2, it connected at 4320kbps which of course killed my IP profile which dropped to 3.5Mbps according to BT's speed tester. I changed some settings and rebooted the Netgear and it connected at 6976Kbps and it stayed at that for over 2 days, the IP profile jumped to 6Mbps after the first 20 hours. It then dropped to 6528 kbps and stayed there, IP profile 5.5Mbps, rock solid. Everything seemed to work fine, however no Wi-Fi.

I've been able to run RouterStats on the Netgear. The SNR value goes to 0dB during the evening and returns to about 5-6dB during the day. The Bright Box stats screen had been reporting -1dB and -1.4 at one point, but until the disconnects it stayed around the 4dB-6dB most of the day. I can not run RouterStats on the Bright Box as the stats page has a dynamic url (the number on the end of the url keeps changing every time you refresh the page) and it seems to use javascript. Router Stats does not seem to be able to render a stats page that uses java, so it can not read the figures.

My line attenuation by router...BT HUB2 42dB, Bright Box 43dB, Netgear 44dB
I have the MTU at 1500 on the Netgear. It is limited to 1492 on the Bright Box.

BT's speed test has returned differing results,
2.48Mbps
4.92Mbps
1.45Mbps (Speed test Beta at same time 6.18Mbps)
6Kbps (after logging in using the BT domain the further speed test gets 50% complete and then fails due to unknown error)
581Kbps (Unknown error occurred after the further test was 96% complete)
333Kbps (Same error as before when doing further tests, Beta test shows no problem with 5.5Mbps)
3.53Mbps (Speed test Beta a moment later gave 5.69Mbps)

Other speed test sites including Thinkbroadband, speedtest.net show much higher figures of 4.5Mbps to 6Mbps. But retests moments later can be different by as much as 1Mbps or more on some occasions.

I decided to put the Bright Box back on and give it a second chance, just in case it was another problem on the line. True to current form it has started to go up and down through the ranges again. It makes it very difficult to run services like Messenger as you can not keep a constant connection and the IP keeps changing forcing the software to log in again. Constantly waiting for it to reconnect is a pain in the bum. As you can guess I am far from impressed with the Bright Box. It has re-synced 3 times while I've been typing this. I've composed this in OpenOffice before pasting into the web browser for posting. It would not have stayed connected long enough for me to log in, type and then post. Suffice to say I'm going back to the trusted Netgear for now.

I think it is faulty, but I would appreciate any ideas on what this could be.

Hello Kali,

The noise margin on your line for both routers is too high and will require some help from Orange to resolve the issue.

If you haven't already reported this issue, please call on 0844 873 8586*, or call 150 free from your Orange pay monthly mobile. We�re here from 7am-11pm, every day.

Best Regards

Gavin

* Calls from an Orange Home Phone are free. Calls from a BT landline or your second line (if you have one) cost 5.1p a minute. Calls from mobiles and other networks may vary. Calls may be monitored and recorded for training purposes.

BrightBox would seem to be faulty as Netgear OK (but no wireless).

Get Orange to replace and/or buy new Netgear DG834GT or DG834Gv4 on eBay or < £20.

I know this bumps and older post up the list but I have an update and the problem is not solved. Thanks for your suggestion Gavin(UKDoc) but things have not gone well. I have since had 3 conversations with Orange and I'm convinced I'm flogging a dead horse with these people.

Conversation 1...

I explained the problem about the Bright Box re-syning and going so fast that the stats page shows nothing be errored seconds and I have no internet. Also that it re-syncs in the middle of doing something (i.e. banking the other night) and now I've noticed that it randomly (no pattern I recognise) blocks traffic as well. IE and Messenger, Windows Live mail all say there is no connection from time to time, even though Windows is not reporting a problem and the Router reports that everything is fine.

He said there was an update and he would remotely send it and I had to press the reset on the back to get that to work. The on board software still reports that it is from November last year which if I remember correctly was what it said when I first got it, so what has been updated I don't know.

I also explained that I had tried all combinations of router and filter and that I thought the Bright Box was fault. He asked me to conduct at least 3 speed tests using BT's speedtester and call back again in the morning from an alternative number so they could test the line and look at the problem again as the call centre was about 10 minutes from closing.

Conversation 2...

I had to call during the evening after work but had time to conduct 3 tests an hour apart the previous night, 1 at lunch time and another early evening. They all fell in the range 4.38Mbps-4.53Mbps, it had resynced in the night but the IP profile was still 5Mbps. Not bad figures but in the real world web broswsing was veeeerrrrry slooooowwww, with some pages not loading at all. Though it might settle down, but I made the call to Orange with the speed test results, although surely they should get them from BT.

I spoke to another man that said I should change the filter, even though I had already done this all before he insisted on it. Compared to my faceplate filter the provided filters have always resulted in at least 0.5Mbps less in speed and that is what happened. He also told me to unplug the filter while it was all switched on and connected, and change it over quickly. I did this even though I believe it was not a very good way to do it as the exchange may interpret it as fault and set a lower sync speed. It did go slower down from 6.3Mbps to 5.3Mbps He kept telling me that I have a very good speed, I said I'm not disagreeing but the constant re-syncing was ruining my ability to use the service. I told him I think it is faulty as my Netgear seemed to hold the line well enough at a much higher speed. At one point he said I had a 2mb connection, like he was reading off another script, not sure why? He told me to call back latter before the call centre closed at 11pm to report any changes.

NOTE: I forgot to add that this call centre worker got me to change the settings on my Wi-Fi from channel 11 to 9 and 20Mhz to 40Mhz. He seemed to suggest that altering the Wi-Fi would make it work better. Go no problem with the Wi-Fi it's the ADSL that won't work properly!

Conversation 3...

I called back as asked just over an hour later as the Bright Box had re-synced a few times (AGAIN!) from 5664Kbps to 5696Kbps to 5856Kbps to 5568Kbps to 5600Kbps. It's has managed to hold that last speed for 1 hour now while I type this, wow! BTW I'm again typing this offline in OpenOffice before posting, just in case.

The man I spoke to this time said he would look at the notes and after a long period of silence (call centre background chatter) he said my connection was 2mb, eh? The other guy said that, what is going on? I corrected him and said the profile was 5Mbps, at least before the filter change earlier in the evening. I explained that the Bright Box appears to be faulty. He said please wait (more background chatter) and after a long wait, he hung up on me!

So, what do I do?

I copied the Bright Box log during 2 of the silly re-sync sessions it has had. 1st log covers just over 1 hour (19:06 to 22:14) on Monday May 21, it shows it loosing the connection 6 times. The 2nd log covers almost 3 hours (20:29 to 22:17) on Friday May 25, again it shows it loosing the connection 6 times in this period.

I've had this problem for a few months now and they don't believe me. The call centre staff are hopeless and clearly don't seem to know what they are doing. They seem to think off the shelf solutions like switch it off/on again is the answer. Between phantom updates (did he actually do anything, it was all rather quick and nothing changed), and insisting my connection is slower than it is then hanging up on me. There is no one else to speak to. What do I do? Any suggestions gladly accepted.

Please help!

NOTE: Gone back to Netgear router, I can not put up with the intermittent behaviour of the Bright Box even though I loose the Wi-Fi. The Netgear has synced at 6304Kbps and been rock solid for over 3 hours now, the Bright Box would have changed spped a few times by now.

Don't speak; write formal complaint!

However you have an obvious solution; use the Netgear and bin the DimBox.

Connection Speed 6528 kbps 448 kbps
Line Attenuation 44 db 14 db
Noise Margin 2147483647 db 27 db

Ok here we have a problem. The noise margin goes to this high figure when the noise margin goes below 0. It SHOULD NOT be doing this. A line will lose stability with a noise margin of around 1.5 db and below.

The noise margin should sync at 6db and move around between 5.5 and 6.5 db on a stable line. My noise margin varies between 5.8 and 6.2 dB. So no big variations.

I've been able to run RouterStats on the Netgear. The SNR value goes to 0dB during the evening and returns to about 5-6dB during the day. The Bright Box stats screen had been reporting -1dB and -1.4 at one point, but until the disconnects it stayed around the 4dB-6dB most of the day. I can not run RouterStats on the Bright Box as the stats page has a dynamic url (the number on the end of the url keeps changing every time you refresh the page) and it seems to use javascript. Router Stats does not seem to be able to render a stats page that uses java, so it can not read the figures.

You have said it yourself. The noise margin goes to -1 dB and - 1.4 dB... At anything below around 1.5 db the line can drop out and resync. Some lines even struggle to hold on at 3dB

Often however when the noise margin is so low - the line stays connected but the error build up is so high and therefore websites don't actually load.

I don't think the bright box is broken I just think it's more sensitive to the excessive noise on your line. The BT home hub is very good at holding onto a broadband connection even with a flappy noise margin.

Orange can increase your target noise margin to 9 dB or 12 dB which should prevent the noise margin going so low. This will cause you to loose speed BUT will increase the stability quite a lot. I think this is the answer to your problems.

If the noise margin is set to 15 dB target and the noise margin is then still dropping extremely low the ISP should send out an engineer.

Have orange increase the noise margin slowly. E.g. try 9 dB target, then 12 dB if it's still dropping, then 15 dB if it's still dropping.

Each increase will make you loose some sync speed.

Unfortuneately, getting blood from a stone!

Agree with rest of your analysis

Thanks UKHardy07, your advise is sound but as XRaySpeX points out it is like getting blood from a stone.

I realise in hind-sight that even the first person I spoke to, as much as he sounded like he was listening, he was also following the same script that the other 2 where following. They suggested everything was fine and did not even know what speed my service was running at, so they clearly don't have relevant information at hand. It is impossible to deal with someone that will not actually act on what you are saying, and insists on doing things you have already done and other things that have no affect (like changing Wi-Fi settings).

Doing repeated line-tests from their end has the same result as most of the recent download tests, at the moment the test is made the line works well and the speed test results look good. So no apparent problem spotted and that is where I am suffering. They don't believe me and it is what I am experiencing (which they have not seen) against their data which is flawed because it is taken at a time the fault is not apparent.

They told me to call back when it happens. I did and they still don't believe me because by the time I get through the call centre menu and then explain it to them, there is no fault as the Bright Box has reconnected and runs fine for while (if only for a few minutes sometimes). If BT had passed along any data from the previous really slow speed tests conducted the other month then they would see there is a problem. They clearly have no access to records of my router disconnecting repeatedly or they would see that straight away and agree with me. They should have all the data and the answers instead of asking me to do silly filter changes and even more speed tests, which have already been done again and again.

In the end it comes down to the fact they will not listen and so asking them to change anything will not solve the problem. I might as well ask them to make pigs fly, the response would be lets conduct a speed test.

I am seriously exasperated and loosing my patients with Orange, I've never been treated with such disrespect by any company. To add to the problem I recently had post that said I was on an 18-month contract? I did not agree to any such contract and if I had known it was I would never had joined Orange in the first place, I think I have made a serious mistake.

Yes I will make a complaint as the situation is unacceptable.

Sadly I need Wi-Fi now, so the Netgear is not a long term solution but with cash in short supply for now it will have to do for a while. I'm not putting the Thick Box back on until they do something about it.

My question would be what is the modern wireless-N equivalent of the Netgear DG834v2?

Hi, try and use the Orange Bright Box Wireless router as the Wireless access point if it can be configured.

You disable the DHCP in Bright Box

Connect your Bright Box to Negear LAN to LAN.

Nice idea of using the Bright Box as an access point that's a good one and I might try that but I don't trust it...

Tonight I logged into the bright box only to find my connection down to 5376Kbps (lowest for a long while) and the noise margin has gone up to 9db. I've also notice that the line attenuation has changed and has gone up. It is going between 43.5db and 44db at the moment, it had previously always been at 43 on the Bright Box.

After reading the log I've noticed that since 10pm the previous evening it has lost the line (or just re-synced) 9 times. I looked at the log and having just logged in at 8:39 the log says I have logged in at 10:39. It says the line has been up and running for 3 hours 47 minutes, but that would mean been connected long before it's last re-sync. Why the 2 hours difference? The router has not been reset/turned off or anything. Is it possible it taken it's time from an online server that is currently incorrect?

I understand that if there has been a major hitch then the noise margin is often set high and takes a while to come back down. Either way it is constantly re-syncing and the line stat that pretty much stays the same regardless (attenuation) is going up.

I'm planning to go into the local Orange shop later this week on my day off and talk to them about it as Orange tech support is pointless waste of time. I'll see if I can speak to someone there (I can understand) who might be able to get hold of someone that understands the problem. The Bright Box will be a paperweight from now on and will not be reconnected, it's a pile of...

In reply to a post by Kail:

Yes, my log is +8 hours ahead of BST, even tho' Time Settings say it's set to GMT and using a time server, but both of these are unchangeable. Looks like Time Settings are useless.

I notice that if you keep disabling and enabling Time Settings you can keep advancing time by 1 hour (into next day LOL!). But is it worth it?

I went in to Orange shop and they rung the very same call centre. Apparently they don't have anywhere else to call and they don't deal with broadband at all in the shop. Although they sell it as I signed up in the same shop.

He listened to everything I said and suggested that I check the phone for line noise, then call back if there was a problem. So when I got home I put a corded phone in the test socket and dialed my mum. Nothing much to hear, apart from my mum that is. I then dialed the BT quiet line test. Unlike a similar test a year or 2 back which was half quiet and then half pops and clicks. Todays test was mostly quiet apart from a few pops and clicks in the middle of it. I'm not sure how significant that is.

So I called Orange support again. The women I spoke to went through everything and suggested a few things that I had already done. She accepted what I said unlike the others I talked to last week. In the end after hearing that the Netgear managed the line OK, she opted to send a new router as it does seem the Bright Box is not working very well. Although her boss needs to confirm it first and he was not around at the time. I'll find out tomorrow if I ring back to confirm or in 6 days if I wait for the post.

The people I spoke to today were better to deal with and at least I could understand them. Phew!

Another update...

As Orange were supposed to be sending me another router, while I waited I switched back to my DG834 as it was stable and worked. I got a call (left message) from Orange the next day, saying they had tested the line again and it was not the router but in fact the line. I called them that night to tell them it was my Netgear on the line and not the faulty Bright Box. They said they would arrange a call back the next day and the result is that they sent out a Netgear DGN1000SP (Orange branded DGN1000). However I received in the post a jiffy bag with a Netgear power supply and a letter stating they hoped this would solve my problem... ???? The call centre assured me that this was normal and the router should arrive via courier the same day. It did arrive and it was in a bashed box that contained a power supply. The next call centre worker I talked to had no idea why I had a spare power supply sent out.

I connected it up and the next day Orange called back as arranged. It had not re connected at all and was stable like my Netgear, except not like my Netgear...

I was able to run routerstats on the provided DGN1000SP and it displayed a significant difference. For a about a week now the exchange seems to have set a high noise margin. The the line's noise margin has hung at the 8-9db mark and sunk to about 2-3db mark at night. Instead of the 6db mark and sinking to 0db at night. My Netgear DG834 v2 displayed a noise margin graph on routerstats that jumped from 8db to a figure of 2-6db and back again, carving a zigzag across the screen. Mostly at 8db but at least a 3rd of the time well below that.

That happened regularly but the graph the new DGN1000SP router produces is hanging around the 8db mark, going up and down between 7-9db. In fact it seems incredibly stable compared to the DG834 v2. The only thing is that it is connecting at 5600Kbps and after the only reset I have conducted (to kill a continuously flashing WPS light) it has connected at 5376Kbps. This brings me to my next problem.

Since the exchange has imposed the high noise margin (Orange have confirmed that it must the the exchange as they have not done it) every time one of the routers I have used has re-synced, it has synced lower than before, not upwards. This has just happened as I've mentioned with the DGN1000SP when the WPS light would not stop flashing and a reboot was the only option I had left. It also happened with the DG834 v2 and it was syned downwards. The Bright Box that would not stay connected for very long, had gone from about 5952Kbps to about 4896Kbps just before I ditched it for the last time with Orange's approval. Should I be concerned about the downward march of my connection or is it simply a symptom of what the exchange has done?

The ISP offerings carry the widely touted king of the hill the Broadcom chips, as in the Bright Box and my old BT Hub2. They were either very average or in the case of the Bright Box shockingly poor. The texas instruments TI-AR7 chip seems to have done pretty well in my DG834 v2, though I suspect the Netgear firmware has had it's say. Constantly sliding sync rate aside, the Netgear DGN1000SP (SP model carries Orange firmware), Infineon/sercomm (?) offering seems to be holding things as they should be at the moment. Wireless is a bit slow

Orange suggested it could be the equipment and the way it connects that was causing the Bright Box to fail. They said my Netgear DG834 connects in a different way to the Bright Box and the new Netgear should help identify problem. With the DGN1000SP appearing to work Orange have now said that if this continues to works then it is problem solved. I suppose so. My concern at the moment is how long will it take for the noise margin to go back down. If this router continues as it has and holds the line with very little noise margin change, how long should I have to wait?

As I type this the sun has long gone and the noise margin has only dropped from 8.8db to 8db. Infineon rules!... maybe, we will see.

Had an Openreach eng round today to look into a stuck high NM, 12 dB, and low Sync, 15 Meg, after an episode of constant discons over the 2 Bank Hols days. Prior to that it had run at 20 Meg on a 3 dB NM for a whole year.

He told me that he'd have to report back to Orange who are the only ones to control the settings like NM, not even BTw.

Shortly after I had a call from Orange agreeing to set the NMs @ 3 dB Down/6 dB Up and that I was restarting a 10 day training period. Within minutes I was running at 19 Meg on a 4.5 dB NM.

EDIT: You need to get beyond phone support to the Fault Resolution Team to get anything done.

Edited by XRaySpeX (Fri 08-Jun-12 23:12:01)

Thanks for the info XRaySpeX.

I intend to leave the DGN1000SP connected over the weekend, without reboot or power off, to see if anything changes. I think the noise margin is set at 9db as that is the high point which it does not go above. Current router stats...

System Up Time 18:14:19
ADSL Link Downstream Upstream
Connection Speed 5376 Kbps 448 Kbps
Line Attenuation 43.2 dB 27.5 dB
Noise Margin 9.1 dB 28.0 dB

ADSL has been up and running for 18:13:46 since the reboot the other day. My IP profile is at 4.5Mbps and speed tests today on the above stats show...

BT speed test, Down=3.94Mbps, Up=0.45Mbps
BT speed test Beta ,Down=4.86Mbps, Up=0.37Mbps (above 4.5?)
Speedtest.net, Down=4.41Mbps, Up=0.38Mbps, Ping=45ms
ThinkBroadband, Down=4.1Mbps, Up=0.4Mbps


So things look to me to be operating normally and there are no constant re-syncs. For a change the noise margin is holding relatively steady (only a 1-2db change over the day) compared to the other routers. I will give them a call Monday/Tuesday next week so the current problem stays live on their system.

Regarding the noise margin. I did mentioned to Orange the other day, that when I went into the Orange shop the previous week the man I was put through to said he would set my router/line to �always on�. Difficult to tell what he was saying as it was a strong Indian accent and he seemed to speak pigeon English at best. What that meant I don't know but the margin has been high since then. Who I talked to the other day did not know what that was or what that person had done if anything. So I guess if I ask to speak to the Fault Resolution Team and I ask if they can look at lowering the margin, they will know what I mean?

By the way, I've checked the orange website and the members centre area and my problem is not listed in the reported faults section. Not sure if that is for voice faults only and broadband is considered separate.

Thanks for the help

You sync is about 1 Meg slow.

You are on ADSL Max and I'm not sure they would reduce the NM on that; I'm on ADSL2+ where the NM can be reduced to 3 dB.

They never are!! I'm sure they don't use it.

I did not ring Orange in the end. The noise margin has come down to about 5-6db on it's own and the router re-synced (upwards) at that time to 6272Kbps. It is the only re-sync since it has gone on. RouterStats shows the noise margin holding steady and it sinks no lower than 4.4db during the night. IP Profile is still at 4.5Mbps but I would expect that to follow soon.

I noticed that the noise margin on the DGN1000 flucuates in steps of 0.1db so it draws a fairly steady line across the on screen graph. The DG834 flucuated in steps of 1db and dropped as much as 4db before jumping back up a few moments later. It drew a kind of flat topped zigzag. The DGN1000 seems to be in control and despite the previous problems with the line it is holding good.

Stats...
System Up Time 97:40:29
ADSL Link Downstream Upstream
Connection Speed 6272 Kbps 448 Kbps
Line Attenuation 43.3 dB 27.5 dB
Noise Margin 5.1 dB 28.0 dB

I guess that is +1 to Orange in the end for a guessing right that it was the Bright Box, that based on the information about my DG834 performance. It has taken a lot of hassle, but it is seriously beginning to look like problem solved. An Infineon based router seems to be the answer for my line.

Thanks to everyone on this thread for all the help and suggestions. Hopfully this thread can be left to sink now.

Spot on! Fingers X'ed it stays that way
