my laotop is the asus s5c, which haven't minipci wireless card in it.so i use a wg511 pcimia wireless card which can work well in linux instead.but after i installed it sucessfully, i found wg511(as eth1) can not work together with the original realtek8139(as eth0) link. if i want to use wg511, i have to "ifdown eth0" first, or if i want to use 8139, then i have to "ifdown eth1".
anyone know why and how to resolve the problem?
