Hi; I'm starting to experience internet slowdown with my 4 year old Netopia 2241N modem and I'm pretty sure it will need to be replaced soon. Currently, I have AT&T DSL (1.5 Mbs) and only one computer (a desktop), so wireless capability isn't needed. Does anyone have an opinion as to what would be for my basic needs the best DSL modem with firewall in terms of quality and performance. I would like to keep the price below $75.00 . Thanks in advance for any advice.
