I had ATT uverse service which used a 2Wire modem which I understand is DSL. They used coax to the house for Internet & cable. I changed cable companies to WOW. I need wireless for my daughter's laptops. Trendnet modems I used before didn't have much range. The 2Wire seemed to work well for the wireless. I thought of buying a cheap used one on EBay. Does the 2Wire only work with ATT service? Is there something better for a modest price?
