hello im trying to install drivers for my dlink-g122 revb1 usb dongle. i have d/l the drivers from serial monkey and followed what i thought to be a good how-to. Well the build went fine but i still have no wireless. when i run modprobe rt2570 i see this

root@g-8f3fcf61ec554 ~]# modprobe rt2570
FATAL: Error inserting rt2570 (/lib/modules/2.6.19-1.2895.fc6/extra/rt2570.ko): Unknown symbol in module, or unknown parameter (see dmesg)
