Reformatted friends computer with windows xp pro. His ethernet connection on the computer doesn't work so he has an ethernet to USB adapter. So his set up looks like this.. Modem to router to adapter to computer via USB. He has a Motorola sb5101 modem, does he need to install modem drivers? We've tried to get drivers for this modem for awhile now and came up with nothing. The closest we got is the drive given from the motorola website but it gives you a zip file with 6 files in it and none of them or .exe files to install. Now on my personal computer there was nothing to even install for my modem it just works... so I'm not sure if the drivers are even needed for this to work.
