I cannot connect broadband when I am in my back bedroom! The basic phone setup is: Main socket downstairs, and upstairs extension socket which is hard-wired into the main socket. The extension socket wiring runs externally around the house and through the back wall. With this setup and with usual filters I cannot connect to broadband. If I disconnect the extension socket from the main socket, so that the only things on the phone line are the main phone and my broadband modem, I can connect via broadband using my laptop downstairs in the main phone socket. Simple I thought, there is a problem with the phone extension or cable. So I bought a plug-in type phone extension cable and a 20m adsl cable which I ran from the main socket downstairs to my upstairs PC, broadband doesnt work! So, I disconnected the plug-in phone extension, so all I had connected were the main downstairs phone and the 20m adsl cable/modem upstairs, still didnt work! I unplugged the modem (still connected to the 20m adsl cable) from the upstairs PC, walked downstairs & plugged it into my laptop downstairs, broadband works (when phone extension is unplugged) OK, theres something somewhere upstairs somehow interfering with the signal, so plugged my laptop into a mains extension cable, still connected to downstairs socket via 20m adsl cable, and walked upstairs hoping to see the connection lost at some point. Needless to say it all stayed connected and I was sat by my upstairs PC with my laptop connected to broadband ok. So unplugged the modem from the laptop and stuck it in my upstairs PC, broadband lost! OK, something wrong with my upstairs PC. Disconnected my upstairs PC, brought it downstairs & connected broadband modem via 20m adsl cable and broadband now works on my upstairs PC when it is in the kitchen!!! Neither BT nor tiscali are interested, and I am on the verge of abandoning broadband and sticking with dial-up. There appears to be no logic or pattern to the problem, can anyone shed any light! Many thanks Bartolli

i got a bit confused reading all that. this might help or perhaps not: I was helping out a friend who had a spaghetti junction nightmare of phone extension cables here there and everywhere and had trouble getting broadband upstairs (BT phone line). It was because some of the adaptors they were using only had 2 terminals in the socket instead of 4. Normal BT phones only need 2 terminals so some makers of the adaptors only put those two terminals in the socket. When all set up with the adaptors with 4 terminals in all was fine. (I am in UK and assume you are in UK as you mention BT - this site seems to mainly be read by americans so it is best to mention you are in UK if relevant to the problem, which it might be here as USA use different phone systems / sockets than UK)

Hi a few other pointers.. Are you connecting your pc via usb? if so change to ethernet Bt dont recomend usb ,, at all, and is the microfilter in the right place ? between wall socket and router. test your new 20 m wire if its bought from £-land forget it, its poor quality. http://www.ukfsn.org/support/adsl.html

Thanks for the comments. Managed to get it working somehow! Before moving my main PC back upstairs, I reconnected the plug-in phone socket extension to the main socket & bband still worked. So I thought I may as well try to rewire the upstairs phone socket extendion into the main soket and bband still worked! This was wierd because it definately didn't work before. Then I moved the main PC back upstairs and bband still worked and is still working now 3 days later! I don't understand this at all because the setup which is now working definitely didn't work before. For info I now have the upstairs phone socket hard-wired into the downstairs main socket (as originally, the upstairs phone is plugged into the upstairs socket via a filter. The 20m adsl extension is plugged into the main phone socket downstairs via a filter with the main phone. Don't understand at all why this didn't work last week and works now. I am connecting using USB, and the phone socket had 4 terminals. Many thanks for your comments. Bartolli
