Connection lost error?

[Lonley]

Hi, I've recently got Broadband through AOL and when I leave my computer unattended, like over night or during the day when I'm at work, in its place of coming home to find it joined I am greeted by connection lost error. Also sometimes even as I'm at the PC I will get a network cable disconnected error on the taskbar and the DSL link light will go out and then flash until it can get a connection with the replace. I've done some digging and it would seem that I'm not the only person with a BT Voyager 105 that’s affliction from this.

From what I can see the modem is at fault and people have suggested purchasing an internal DSL modem. I'm just wondering if anyone can suggest a good one to go for. It's only needed to connect one PC to a 512k Broadband line.

Thanks for your help in advance, have been desperately trying to fix this problem.
