BT2700HGV: Wireless causing the ADSL to drop out

Dark_Light — Thu, 07 Oct 2010 14:31:42 GMT

I have BT Business broadband, and during the past few months I have had drop outs of the internet connection. On the 17th of September I got upgraded to 21cn, before then I didn't take much notice of the drop outs. However when I got the upgrade I didn't get the speed increase that I was expecting. At first I thought this was due to the training period, however this turns out not to be the case. I then found out that due to the drop outs my speed has been capped to 8128.

It turns out that is the wireless that is causing the drop outs, I have turned the wireless off and as a result there is no more drop outs.

How do I solve this problem, is it a faulty router, or can I fix it by changing some settings or with a firmware update?

Hardware Version:	2701-100589-005
Software Version:	5.29.107.19

I know that I am being capped due to the drop outs, so how long does it take the speed cap to be removed?

Since I am writing this thread I have a few questions I would like to ask.

On the router MDC page I can access the stats page, which states that my max rate is 13000 kbps - 13500 kbps, currently I have a noise margin of around 15db. Does the max rate take noise margin into consideration, so if my noise margin would decrease to about 6db would my max rate increase?

If the cap is removed and my noise margin does decrease what would I likely sync at and would I sync at my max rate?

I am sorry no one on the forum has been able to offer any advice on this issue. Did you manage to get it resolved?

If not there are help and support files if you have a slow or intermittent wireless connection and it recommends trying a different Wireless Channel. If this fails you could talk to the technical support team to see if they can check for a router error. As you did not supply your BTConnect email address when signing up I can not check to see if you have already contacted support.

I hope this helps

Kind Regards
