ive also been seeing all this error messages, wifi sometimes work, most of the time it does not. i installed madwifi to solve this some releases ago, but then some intrepid update broke that and i couldn't get it to work again. using kernel 2.6.27-7, fresh install from today with all updates.
more errors i got: ath5k phy0: ath5k_chan_set: unable to reset channel ($freq mhz) ath5k phy0: noise floor calibration timeout (2437MHz) hardware is atheros AR 242x in leveno thinkpad x200 -- ath5k with AR5424 fails at startup or resume https://bugs.launchpad.net/bugs/269253 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
