Hi Drifter. Losing the connection on Broadband is usually due to problems on the telephone line. Any noise on the line, bad connection etc can cause this. Have you had the line checked by BT? I don't think Tiscali care what modem you are using, but of course they would prefer to support a modem that they know. Failure to be able to connect to Tiscali could be due to the modem not synchronising or may be down to whatever was causing the initial problem. Try with the modem connected to the master telephone socket, and no other devices, telephones etc connected. If this works, then you probably do have a filter or wiring problem.
