The rt2500pci card worked with Feisty herd 4 (kernel 2.6.20-9). The update to 2.6.20-10 broke it. The update to 2.6.20-11 didn't mend it.
The workaround above works in 2.6.20-10, but not 2.6.20-11, possibly because it appears as two devices, ra0 and wmaster0 there. Output of lspci, lsmod, ifconfig and iwconfig for all three versions available. -- rt2500 in feisty: problem & solution https://launchpad.net/bugs/78037 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
