Fit the NTE5 there then CW1308 to where you need extension(s). For the extension with the router use the NTE2000 extension kit OR if you require a phone at that point too use CW1308 and this socket. Remember the extension which has the router on MUST connect to the A & B terminals on the NTE2005 faceplate. The extensions for just phones connect to 2,3 & 5 & do not require plug in filters any more. Hope this helps.
      fantastic! I'll stick the NTE5A on the wall that the wire comes in through, even though it will look stupid - then I will run the necessary wires.

      Should I do all of this after DLM finishes on Thursday or would there be any harm in just doing it now....

      these are my sky stats at present on day 5:

      ADSL Link Downstream Upstream

      Line Attenuation 39.5db 24.4db
      Noise Margin 6.7db 12.5db

      These are the downstairs lady's stats now:

      Re: Poor SNR

      I would do it now because you will need o get Sky to reconfigure it for you anyway if you improve the wiring afterwards.

      Post youe stats from the TEST socket once you have moved the master over and before you aire anything else to it, this should give us your best stats you can get.

      Re: Poor SNR

      Ok good stuff. I'm at my parents now but will be back Sunday/Monday so will chop off gel connectors and IDC directly to nte5a and check stats. If they're crap then only thing left is replacing the whole wire from the junction box. Most likely then I'll have to get BT in and make verything look legit!

      By the way...is there anyway I can get the detailed stats from the nee d-link sky router like I managed with the router for the lady downstairs?

      Re: Poor SNR

      At the moment there is no way to get detailed stats from the Dlink.

      Looking at your downstairs neighbours stats, there is something wrong with her connection. Her line is very heavily capped, probably due to the large amount of errors.

      Re: Poor SNR

      Yeah I was wondering about that because her transfer rate was always near 8mbit downloading at least 700k. When we moved in she gave me her router key hence I can use her net. It was ever since I disconnected my extension wire and ring wire that my sync speed went from 3500 kbit to 6000 kbit and attenuation went up from 28db to 41db on virgin 2 weeks back. Perhaps that somehow weirdly affected her connection. Or it could have been the sky engineer rushing a late installation of the sky minidish...who knows. Only after seeing the detailed stats did I realise she isn't synced at 8mbit and that download speeds are around 300k now...

      Re: Poor SNR

      Hey guys. Didn't have time to fully Rewire but replaced the gel connectors with a spare junction box disconnected from an extension (screw type terminals)

      During the work my noise margin went up to 8.6 and attenuation dropped to 36 but by the Time I was done it went back to same values as before...

      Will see how the nte5 move fares me.

      If that's no good then

      1. Wire from external junction box into kitchen is noisy
      2. Junction box terminal is faulty
      3. Drop cable is poo
      4. Don't hav a clue

      Re: Poor SNR

      Moved nte5 to where the wire comes in

      Same stats as before....connected B to blue and A to White blue. Haven't screwed box together but doubt it would make a difference.

      Any advice

      Re: Poor SNR

      In case it helps here are the photos of my NTE5A inside the kitchen window and the external black junction box with the black wire going into the open kitchen window

      The other white wires I presume are going to other flats and the fat black cable going in from the bottom is the drop cable...





      I really hope I can get a speed boost...it still doesn't make sense that I had 28db attenuation before I started doing things and now its 39db and that the downstairs used to sync around 8mbit but now syncs around 3.3mbit....

      Weirdness...it doesn't make sense, given the fact that I've totally eliminated house wiring
