Im having a problem with my friends wireless router and pci card, both are netgear, the pci card is 802.11g and the router is 802.11b, it was working for a few minutes when i reformatted the comp, but now it only sends packets and does not recieve them, the internet works fine when its wired, and other comps work wirelessly, and the signal strength is always excellent. does anyone know how to fix it so it will recieve packets?
