thanks for getting back again. I noticed that i didn't have a BT Master Socket (NTE5) as i think i replaced it with a plain socket during some routine DIY. Last night, i replaced this with a socket that has a microfilter fitted (it has a phone socket and an ADSL socket).

As i only have a wireless router, can i check wired connectivity using the laptop's internal modem or do i need a special ADSL modem (in which case i can go and buy one).

Another issue - i have a phone extension upstairs in an office - will this work for ADSL also or do i need some special extension?

Thanks again and sorry for the extreme lack of knowledge!!
