Is it my computer, my router, or my line??????


[link to this post]
 
Sorry to be a nuisance / dimwit, but the views of wiser heads than mine would be much appreciated. My 'Net connection has never been good, never been stable, but because of my distance from the BT exchange, I've had to put up with it. These past couple of months though have driven me mad -- but I can't figure out if the router is to blame, or the line quality is to blame, or even the blasted computer.

Here are the kind of problems experienced in just the past week alone, involving:
1. Computer: Windows running Vista OS.
2. Broadband service: BT Broadband.
3. Router: Netgear DG834G. This router is on the ground floor of our 2007 new-build three story home and is connected directly to the BT master socket. This socket has been modified using a BT faceplate to separate ADSL usage from phone usage; the router is plugged into the ADSL socket.
5. The router transmits wirelessly to a Netgear WG111v2 54Mbps wireless USB 2.0 adapter positioned under my desk and connected to my computer in my top floor study.
6. The wireless signal strength between the router and the adapter is consistently 'excellent' and is monitored as-and-when by inSSIDer Mini sofftware which shows a steady 54 to ]56 amplitude and no channel proximity to any neighbouring users.
7. BT rates my line at 1.0Mbps.
8. The kind of hair-tearing situations are:

One week ago, on Wednesday December 19th, my Router Stats Lite software was reporting:

Time: 15.30 Noise Margin= 16.8, Sync Speed= 1376, Upstream NM= 6.0. Yet I had no Internet connection at all.

When I clicked on my tray icon it merely said: 'Local connection only'. I disconnected, re-connected, and eventually even re-booted the computer but to no effect: it was still 'Local connection only'. Finally, I gave up and went down three flights of stairs to the master socket, switched off the router, waited around for a while and then turned it back on and:

Time: 16.12 Noise Margin= 15.3, Sync Speed= 1568, Upstream NM= 10.0. And everything was fine again: full connection, even when shortly after, I then lost all connectivity for 5 minutes and when it resumed, RouterStats Lite reported:

Time: 17.28 Noise Margin= 16.4, Sync Speed= 1184, Upstream NM= 6.0.

I left the computer switched on (not in Sleep mode) all night on Wednesday and those stats remained constant. However, on Thursday afternoon I put the computer into Sleep mode for a couple of hours and when I woke it up again, this was what I faced:

Thurs December 20: 17.28 Noise Margin= 17.6, Sync Speed= 896, Upstream NM= 12.0.

The Internet was at a crawl, or felt like it, but I persevered regardless and didn't re-boot or re-set but just left the damn thing alone until putting the computer into Sleep mode late that Thursday evening.

On Friday December 21, when awakening the computer from Sleep, I had 'Local connection only' and this slight change in the stats:

Fri December 21: 10.05 Noise Margin= 16.8, Sync Speed= 864, Upstream NM= 9.0.

So I again hopped it down three floors to the master socket, switched off the router, waited around, turned it back on, went back upstairs and now the stats read:

Fri December 21: 10.28 Noise Margin= 14.2, Sync Speed= 1536, Upstream NM= 11.0.

And it stayed like that, with full connectivity and the computer never switched off / never put to sleep until Sunday last:

Sun December 23. Time: 22.40. Noise Margin= 13.6, Sync Speed= 1536, Upstream NM= 11.0.
The computer was then put into Sleep mode overnight.

Next morning, Monday December 24, the computer was awoken from sleep but the tray icon indicated there was no connection. Clicking on the icon brought up the message "Connected but with limited access" and yet, and yet, RouterStats Lite was simultaneously reporting:

Monday December 24. 09.05. Noise Margin=15.0, Sync Speed= 1536, Upstream NM= 11.0.

And yes: I had fully functioning Internet connectivity, despite the computer saying I hadn't. Just to check though, I disconnected and reconnected using the tray icon (NOT a router re-set) and this time the tray icon confirmed the connection, the computer no longer warned of 'limited connection only' -- but RouterStats Lite now reported a sudden halving of sync speed::

Monday December 24, 09.23. Noise Margin= 15.1, Sync Speed= 896, Upstream NM=11.0.

I then went downstairs and switched off the router for 5 minutes to re-set it, then came back to the top of the house again and tried to connect again and. . . Nothing. The router wasn't synching at all. Eventually, I re-booted the computer and now:

Monday December 24 10.28. Noise Margin=15.4, Sync Speed= 1600, Upstream NM= 11.0.

So we're back to where we started. At this time, I also ran a Broadband UK speedtest and obtained the following results:

1341.85 Kbps (1.3 Mbps) DOWNLOAD / 373.98 Kbps (0.4 Mbps) UPLOAD

In view of the line length here, I didn't find anything wrong with Speedtest's findings.

However. . . Later in the day, I experienced line drops when the Noise Margin would suddenly plummet from 15.0 or thereabouts to less than 1.0 -- a fairly regular occurrence. But then the connection was suddenly OK again.

I left the computer switched on all night on Monday night and then checked the Internet connection / RouterStats Lite log yesterday morning and the stats were pretty much the same:

Tuesday December 25 08.16. Noise Margin=13.6, Sync Speed= 1600, Upstream NM= 11.0.

I left the computer on all day yesterday, though didn't use it, and finally put it into Sleep mode at 11.30pm last night when the stats at that time were similar to those in the morning.

Today, I awoke the computer from Sleep at 19.22 and this is what I find:

Noise Margin=16.4, Sync Speed= 864, Upstream NM= 9.0. Broadband UK Speedtest reports:

493.03 Kbps (0.4 Mbps) DOWNLOAD / 356.42 Kbps (0.3 Mbps) UPLOAD

Everything is at a crawl again. In summary:

I never know when my Internet connection is going to drop altogether, or become Local Connection Only, or be red-flagged Connected with LImited Access (except it isn't) and I never know from one day to the next what upload/download speeds I'll have or what if any consistency there'll be in the stats.

I seem to spend half my life in running up and down re-setting the router or wasting time re-booting the computer or re-connecting from the tray icon. It gets wearying. I do have the latest version of TCP Optimizer for Vista 32-bit but I have this set at "Windows Default" as a previous experience of using it to provide 'Optimal Settings' changed nothing at all in terms of Internet connectivity, reliability or speed.

Apologies for the length of this post but I thought I'd provide as many facts as possible. I don't fully understand what those stats signify but hopefully they'll mean a lot more to others. If anyone can advise on whether I should be buying a new router, or a new computer, or a new house next door to the BT exchange, that'd be appreciated. Thanks.

I can't read all that, but you seem to be having trouble with the sync speed. So let's have the verbatim full router stats, when it;s bad and when it's good, to see if you are getting what you should. After which we can consider wireless.

1999: Freeserve 48K Dial-Up => 2005: Wanadoo 1 Meg BB => 2007: Orange 2 Meg BB => 2008: Orange 8 Meg LLU => 2010: Orange 16 Meg LLU => 2011: Orange 19 Meg WBC

There are plenty of potential faults or areas of fault and it could be a long process to eliminate them one at a time.

I am surprised that you get "Excellent" signal strength and 54 Mbps over 3 floors ... but then I am always suspect of the indicators.

As suggested a full set of stats from the router would be useful along with a RouterStatsLite plot showing sync and SNR margin, sampled at 10 second intervals for te period up to a disconnection/freeze or two. It might throw some light on the problem. And if you can do it for both DOWN (essential) and UP it would be very useful.

Also, are you in a position to get an Ethernet cable that will run (rather untidily) from router to PC? That will give you better control of te router and modem and allow wireless to be eliminated.

there are various options for rebooting the router or disconnecting / reconnecting the PPP session etc via the web interface of the router, to save you running down stairs.

What';s the downstream attenuation ?

In addition to the other suggestions...

Dare I suggest it considering the time of year... Sudden drops in noise margin like that may well be Xmas lights - yours or the neighbours. Also, have you checked every phone is properly filtered? Have you tried running the router from the test socket?

It is strange that it seems to lose sync when the PC is turned off but I suspect (and hope) that is just coincidence. The PC may also not be coming out of sleep well and so may be part of the problem with Internet access - not all network cards like sleep mode - I tend to do a full shutdown when I am not using the PC for a while (takes a little longer to boot but can avoid issues).

Hello Philnoob,

The thing I like about Netgear routers, is the way it records an activities log inside the router.
Log into your router with your web browser on 192.168.0.1 and enter Admin and your password. On the left menu, click on LOGS.

As long as you haven't rebooted the router recently, it will list how many times the router lost connection. Sometimes it can tell you how/what caused the disconnections.

Also the statistics on the router stats page are quite usefull aswell.

[re: wanapoo] [link to this post]
 
First of all: sincere apologies for taking up the time of everyone here. I really can't get my head around this wireless stuff despite various blundering attempts! But I also have to thank you all for the advice given so far because I've at least managed to follow some of it. Anyway. Here's the update as of this past hour (10.30am to 11.30am today, Thursday):

1) Computer put in Sleep mode overnight and awakened at 10.30am. RouterStats Lite reported:

Noise Margin= 16.8, Sync Speed= 864, Upstream NM= 9.0

Pretty much the same as when the computer was put in Sleep mode.

2) The Netgear router's own stats confirmed this as follows:

Connection speed: Downstream: 864 kbps / Upstream 448 kbps
Line attenuation: Downstream: 63.5db / Upstream 31.5db
Noise Margin: Downstream: 16.8db / Upstream 9.0db

3) I hadn't realised I could remotely reboot this router instead of having to trundle up and downstairs every time. (Sorry about my ignorance.) So I went into the router's Diagnostics panel and re-booted from there. After a few minutes, this was the result according to the router's own stats:

Connection speed: Downstream: 1600 kbps / Upstream 224 kbps
Line attenuation: Downstream: 63.5db / Upstream 31.5db
Noise Margin: Downstream: 15.3db / Upstream 5.0db

This was initially mirrored in RouterStats Lite log but then this happened:

Thu 27 Dec 2012 11:41:46, Noise Margin= 15.3, Sync Speed= 1600, Upstream NM= 6.0
Thu 27 Dec 2012 11:42:01, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:42:16, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:42:31, Noise Margin= 15.6, Sync Speed= 1568, Upstream NM= 6.0
Thu 27 Dec 2012 11:42:46, Noise Margin= 15.8, Sync Speed= 1568, Upstream NM= 6.0

Thu 27 Dec 2012 11:43:16, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:43:31, Noise Margin= 15.5, Sync Speed= 1600, Upstream NM= 6.0

Thu 27 Dec 2012 11:44:16, Noise Margin= 15.4, Sync Speed= 1600, Upstream NM= 7.0
Thu 27 Dec 2012 11:44:31, Noise Margin= 15.4, Sync Speed= 1600, Upstream NM= 7.0
Thu 27 Dec 2012 11:44:46, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:45:01, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:45:16, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:45:31, Noise Margin= 15.5, Sync Speed= 1600, Upstream NM= 9.0
Thu 27 Dec 2012 11:45:46, Noise Margin= 15.6, Sync Speed= 1600, Upstream NM= 9.0
Thu 27 Dec 2012 11:46:01, Noise Margin= 15.4, Sync Speed= 1600, Upstream NM= 9.0
Thu 27 Dec 2012 11:46:17, Noise Margin= 15.5, Sync Speed= 1600, Upstream NM= 9.0
Thu 27 Dec 2012 11:46:31, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:46:46, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:47:02, Noise Margin= 15.4, Sync Speed= 1600, Upstream NM= 7.0
Thu 27 Dec 2012 11:47:21, Noise Margin= , Sync Speed= , Upstream NM=

So right now, I have no Internet connectivity. At all. The connection has vanished in the middle of writing this -- oh, whoops, now I have the connection back again:

Thu 27 Dec 2012 11:47:21, Noise Margin= , Sync Speed= , Upstream NM=
Thu 27 Dec 2012 11:47:57, Noise Margin= 15.4, Sync Speed= 1600, Upstream NM= 6.0
Thu 27 Dec 2012 11:48:12, Noise Margin= 2.6, Sync Speed= 1600, Upstream NM= 6.0
Thu 27 Dec 2012 11:48:27, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:48:42, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:48:57, Noise Margin= 16.0, Sync Speed= 928, Upstream NM= 6.0
Thu 27 Dec 2012 11:49:12, Noise Margin= 15.9, Sync Speed= 928, Upstream NM= 6.0

The router's own stats are now:

Connection speed: Downstream: 928 kbps / Upstream 448 kbps
Line attenuation: Downstream: 63.5db / Upstream 31.5db
Noise Margin: Downstream: 15.6db / Upstream 6.0db

Quite how long I'll have this connection, I've no idea. Oh, as to some earlier points:

1) We don't have any filters installed in any extension sockets anywhere in the property. We were told the filters were not necessary because the router is plugged directly into the ADSL socket of the BT face-plate on the Master Socket. We were told that doing this precluded the need for filters and also meant the router was connected to a point where it could not be affected by problems arising from the house's telephone extensions.

2) We don't have *any* Christmas lights, of any kind, inside our pro[perty or outside it. Not even tiny bulbs on our ornamental Chrisdtmas tree in the lounge. Our neighbours on either side of us are away. They don't have any Christmas liughts outside their properties and if they do happen to have any isnside, none are switched on due to their absence. Nor are their computers switched on. We don't have anyone living opposite us.

Apologies again for the length of this post but as it's up-to-the-minute I thought I'd just send it through with all the latest stats. Well: assuming I can actually send it anyway seeing as how this has also just happened:

Thu 27 Dec 2012 11:54:43, Noise Margin= 15.5, Sync Speed= 928, Upstream NM= 6.0
Thu 27 Dec 2012 11:55:13, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:55:28, Noise Margin= 15.4, Sync Speed= 832, Upstream NM= 6.0
Thu 27 Dec 2012 11:55:43, Noise Margin= 14.8, Sync Speed= 832, Upstream NM= 6.0
Thu 27 Dec 2012 11:55:58, Noise Margin= 15.3, Sync Speed= 832, Upstream NM= 6.0
Thu 27 Dec 2012 11:56:13, Noise Margin= 14.6, Sync Speed= 832, Upstream NM= 6.0
Thu 27 Dec 2012 11:56:28, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:56:43, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:56:58, Noise Margin= 15.3, Sync Speed= 832, Upstream NM= 7.0
Thu 27 Dec 2012 11:57:13, Noise Margin= 15.2, Sync Speed= 832, Upstream NM= 7.0
Thu 27 Dec 2012 11:57:32, Noise Margin= 14.8, Sync Speed= 832, Upstream NM= 7.0

Thu 27 Dec 2012 11:58:28, Noise Margin= , Sync Speed= 0, Upstream NM=
Thu 27 Dec 2012 11:58:43, Noise Margin= 15.3, Sync Speed= 864, Upstream NM= 7.0
Thu 27 Dec 2012 11:58:58, Noise Margin= 14.9, Sync Speed= 864, Upstream NM= 7.0
Thu 27 Dec 2012 11:59:13, Noise Margin= 14.9, Sync Speed= 864, Upstream NM= 7.0
Thu 27 Dec 2012 11:59:28, Noise Margin= 14.9, Sync Speed= 864, Upstream NM= 7.0

In other words, the connection is repeatedly failing this morning. . .

Re: Is it my computer, my router, or my line??????


[re: Philnoob] [link to this post]
 
OK, so one of 2 things at the moment.

1) Line problem. You are losing margin and sync due to noise on the line. Once the noise gets high the line disconnects.
2) Router problem. Could be a hardware issue with the router.

Personally I plump for number 1. Looks like you have a very long line and it could be that all the bad weather has got water into a connector somewhere or wind is causing intermittent connections. At this point I would be inclined to log a support call with the ISP to report intermittent connection as it is up and down at quite a rate by your latest logs.

Be prepared though - if BT don't find the fault then they could say the line is not suitable for ADSL and stop delivering service - this is worst case but it does occasionally happen. The fact you are losing over 15dB in noise margin though suggests there is something wrong.

The only other thing I would say is worthwhile is to use the test socket. Whilst the faceplate you have should stop interference it may be a faulty faceplate. So, take the faceplate off and use either a converter or filter to plug the router lead directly into the test socket. If it still is a problem then it is most likely outside of your property. If you have a spare router you could also rule out the router by using that in the test socket to see if problem continues.

We have a BT Home HUb router that came with our broadband service contract which we've never used. So I'll follow up Ian's recent suggestion. (Again, sincere thanks to everyone for all the help and advice so far.)
