I have the same problem too (iBook G4 1.3 GHz, edgy-ppc knot2 with all updates current) -- the zd1211 firmware won't load.
A little googling revealed that there is a newer firmware available: http://zd1211.ath.cx/wiki/DriverRewrite http://sourceforge.net/project/showfiles.php?group_id=129083&package_id=187875 After installing the new firmware to /lib/firmware/zd1211/ I found that the new firmware would load, but my usb wireless device is still not working. Dmesg reveals an "eth2: link is not ready" error: [ 482.559841] usb 4-2: new high speed USB device using ehci_hcd and address 2 [ 482.693331] usb 4-2: configuration #1 chosen from 1 choice [ 482.946570] zd1211rw 4-2:1.0: firmware version 4605 [ 482.988582] zd1211rw 4-2:1.0: zd1211 chip 07b8:6001 v4330 high 00-12-0e AL2230_RF pa0 g-- [ 482.991186] zd1211rw 4-2:1.0: eth2 [ 483.592492] ADDRCONF(NETDEV_UP): eth2: link is not ready -- zd1211 no longer working (missing firmware?) https://launchpad.net/bugs/58259 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
