So I finally got my Power Mac G5 a proper airport express card after using an iffy usb dongle for about a year now. For about a day, it worked perfectly, and now it is choking on everything. I am able to get about a couple of packets though before it stops functioning. Although my router is maybe 20 ft away, it shows the connection strength as really low, and neither the fourfold or safari are able to load a thing. Any ideas?
