i have comcast hi-spedd internet with an arris modem and need to hook it to my pc via USB not ethernet "broken ethernet port" but it says put in disc to INSTALL drivers but vista is supposed to just work with the usb support with no need to install drivers but it still asks for the install disc. How can i hook up my pc to internet with the usb cord? I don't think there is even a driver software for the modem so what do i do?A new NIC/PCI card is 10 BUCKS including the driver cd...this is the way i'd go.I found the software disc for the modem the usb now works but the network SPEED is only 12.0mbps dose usb only operate up that high or is somthing wrong? I know ethernet is 100.0mbps and i had a WIRELESS g usb adapterthat was 54.0mbps,so if a usb cord only operates at 12.0mbps then how is it possible for a wireless usb adapter to go any higher its still the same usb technology so how dose that work?is yous usb cord plugged into the front or the back of your comp...if yourcomp has both the back is 2.0 (high speed) and the front is usualy1.0..when you plug in the front you should get a message some thing like (your devise can operate at a higher speed ect.)The Topic is 7 months old...
