      There could be many reasons for this, one being your SNR is dropping at around 7pm.
      The more likly one that I was experiencing is actually because of Sky's modified firmware, however i think its against the T&C to put the Netgear version onto the router.

      Have a look in Tutorials :

      Disconnections - switch off UPnP on router homepage

      Speed - try TCP Optimizer (7pm is in peak usage)

      Re: speed dropping/disconnections

      Sorry to contradict UndeadDevil and tdbsolutions but in my opinion it is neither due to Sky's firmware or UPnP. Certainly TCPOptimizer can't help at all as this tool can only affect download speeds (it "optimises" TCP/IP settings - no relevance to "peak usage").

      Losing connection in the evening is quite common for high(ish) attenuation, high(ish) noise lines. It's due to rising noise which is seen as a falling noise margin. This is an entirely predictable process with noise changing in a regular cycle through the day. The cause is down to a number of things, the main being environmental (changes in temperature, sun activity, rf etc.) and the impact of crosstalk (other users).

      I've written this up in some detail and described two simple "cures" in the first sticky in my signature at the bottom of this post.

      Re: speed dropping/disconnections

      Thanks for the responses, So at the moment there is no solution except to reboot the router, Never mind I'll just have to wait for Sky to come up with a solution, I have posted my stats from the the router.

      ADSL Link Downstream Upstream
      Connection Speed 14026 kbps 574 kbps
      Line Attenuation 21.5 db 12.4 db
      Noise Margin 6.9 db 7.5 db

      The router is connected to a 20m telephone extension it's in a bedroom, I know if I plugged it in directly the stats above would be better.

      Thanks for the help anyway

      Re: speed dropping/disconnections

      Noise level is near minimum but thats because of the lead and not plugged into main BT phone junction box.

      Try switching off the UPnP, what ever the others say it stopped my connection dying.

      I would try putting router closer to BT entry point and is it standing upright on the legs supplied as they get hot and may disconnect.

      Also try running stats before and after trying the engineers socket in main BT box.

      Well, you could check the Cabling & faceplate forum, as mentioned in Saturday's first sig. link, then you could have a go at reducing noise...

      e.g.


      - Remove the ring wire (if you haven't already)

      - Fit a filtered faceplate

      - Use better quality microfilters

      - Use a decent quality ADSL extension, instead of a bog-standard phone extension cable, together with a decent microfilter or filtered extension socket.


      etc. etc.

      Did you read the sticky? I described two methods:
      • reboot the router until the NM stabilises then leave it powered and connected. You don't ever need to reboot again OR
      • you use Mognut's utility, then leave it powered and connected. You don't ever need to reboot again


      Whilst either is a mild inconvenience, they only have to be done once.

      The noise margin is not "near the minimum" it is exactly at the router default level, probably because freetoview had just rebooted. Possibly you don't understand the relationship between connection speed and noise margin. The Sky router will always sync at the highest speed it can for a noise margin of 6.9db.

      Turning off UPnP will prevent disconnections caused by the UPnP bug and only disconnections caused by the UPnP bug. As I clearly said, worth trying but probably not likely to help in this instance. No-one that I can see said don't try it.

      Re: speed dropping/disconnections

      Right I have gone back to a wireless connection and I am using a BT micro filter as the netgear ones seem to limit the download speed, new stats below.

      ADSL Link Downstream Upstream
      Connection Speed 15323 kbps 764 kbps
      Line Attenuation 21.0 db 11.8 db
      Noise Margin 12.8 db 13.5 db
