Network Upgrade = Lower speeds


[link to this post]
 
Hi Folks,

Anybody out there had their exchange upgraded to ADSL2+(21cn) and found their speeds have got slower. Our exchange was done a few days ago and my connection has dropped by 1MB. The other issue is that although I am connected to the exchange at (allegedlly) 5086kbps the internet takes forever on initial opening. Before the upgrade the sync speed was 5890-6000 kbps on average.
I have a new DGND 3700 router and have replaced wall socket and adsl v1 face plate but no difference.The noise level is 5.9-6.3 DB so i can only assume the speed,s not going to get any better. Is this the norm or should I be giving off at BT ?

You should switch to ADSL2 and see if that helps.

Tried both 2 and 2+. Ended up just leaving it on auto to see if it would choose the best.

Was 2 faster than 2+ ?

3000Kbps to 5150Kbps is the expected sync range for the attenuation, so if you used to get a 6Meg sync that was pretty amazing.

Was the old service just 21CN IPstream, or Orange ADSL2+?

Just a BT up to 8mb connection. Line etc replaced 2 years ago due to old lines (overhead) causing severe telephone and broadband problems. I (perhaps foolishly ) assumed that on the adsl2+ at a distance of 2.8km from the exchange the improvement should have been seen in upload and download speeds.(upload has doubled).

I have to be honest and say that i did'nt note down the speeds,but there wasn't any significant difference.

Try ADSL2 again, and also note the attenuation. (Post the stats in fact smile).

Please also run a BT speed test and post the results, as that gives extra information.

Is that running wired or wireless?

If it's wired it looks from that as though your ISP is congested. If wireless, that could be the cause and wired would be faster.

The IP Profile is the extra info. That determines the actual maximum speed, and you shouldn't be getting only 76% of that.

What are the stats though on ADSL2? You forgot to post those smile.

Just a bit more detail:

- the connection speed and other stats show us the state of the connection between you and the exchange;

- the IP Profile, explained here except you are on a newer version, so instead of the table and wait times yours is always around 88% of connection speed, determines the actual maximum download and upload speeds;

- wireless speeds are almost always lower than wired, sometimes considerably.

Ye see what you mean, I was reffering to the actual download speed. It dropped by half a meg when I changed over from auto to adsl2 on the router. Thats what i thought it would take time to settle.

Can I ask one more question (as I have no real understanding of the technicalities of broadband provision) does the line " 0-7150kbps" mean that I am still on an" up to 8mb" connection and if so would upgrading to" up to 20mb "make any difference

2.8km straight line, but your cable length is more like 4km.

At around 45 to 48dB range, ADSL2+ runs out of stream, and any improvement is just from ADSL2 mode.

The downstream dropping, is more often down to the fact that you had an excellent matched pair of hardware before, and the modem does not get along as well with the new exchange hardware. OR and perhaps a mixture, that there is now more cross talk on the line.

No, you'll probably sync at the same speed.

I drafted this long ago and forgot to post it, as I got interrupted. Woth adding to what has been said in the meantime.

1 - probably yes, 2 - certainly no.

Stats please smile. Preferably on ADSL2.

When you were getting the near 6Mbps sync, (as MrSaffron says that is pretty amazing though it is possible), was that with this new router or the previous one?

You say you replaced the wall socket and ADSLv1 faceplate. That is the master I assume? You mean you replaced the whole thing, right back to the incoming wires from outside? What make(s) have you put in? Again, was this before or after the sync dropped?

Just a tip as well. Your earlier re-sync's we have asked for have been in daylight. If you do one at dusk, night-time or dawn it is always slower, so not worth doing when looking for speed.

Hi again, in order the answers to your questions are....
1 It was the old router (linksys 300n) that died.
2 Both peices are genuine BT parts
3 They were fitted not long before the upgrade and were working fine

Not that it makes any difference but i used 6mb as an approx ,a more accurate reading would have been between 5700 and 5850. still a good 4.5 to 4.8 on down load speed though.

I have noticed evening and night speeds are a bit slower but it is never a huge difference. Earlier i did comparison speed tests with the only 3 isps i can get through this exchange (at least according to Kitz) and BT offered 2-2.5mb, sky said approx 4.5mb and talktalk 5-10mb. I take it this really is a guessing game with these poeple.

Pity they are so expensive. I just had a look around and all about £75. As MrSaffron says, it could be the MSAN at the exchange and the Netgear just don't get on too well. Appalling though it is, kit pairing does matter.

Having said that, in agreement with what he and I think someone else said, take a look at this graph. No ISP is going to listen to a complaint I'm afraid.
