Re: No wireless: atheros AR5001x, ubuntu 11.04
Golly, we sure have been busy here, haven't we? I think an important clue was given and consistently ignored way back in post #1. Instead of addressing the error, we've installed compat-wireless, madwifi, considered ndiswrapper and done lots of blacklisting and unblacklisting, all to no avail, since the original error remains unresolved:
Before you do the obvious, that is try a boot parameter pci=biosirq, I'd look around in the computer's BIOS to see how the IRQs are assigned. In my several systems, I have the best luck with Auto Select. Please see attached.
[ 15.501196] ath5k 0000:00:06.0: can't find IRQ for PCI INT A; please try using pci=biosirq
[ 15.501271] ath5k 0000:00:06.0: registered as 'phy0'
[ 15.501284] ath5k phy0: request_irq failed
[ 15.501312] ath5k: probe of 0000:00:06.0 failed with error -16
This is a screenshot from an IBM computer, but most brands have a similar selection available.
If you can make a change, be sure to save your changes and let the computer boot into Ubuntu. Check dmesg for the error again. If it still appears, we'll need to load the suggested boot parameter. If so, please see here: http://ubuntuforums.org/showthread.php?t=1613132
Scroll down to How to permanently set kernel boot options on an installed OS (not wubi). The boot option you want is, of course, not nomodeset, but pci=biosirq.
After making your change, be sure to save and close gedit. Reboot and check dmesg for the error. Then we'll unsnarl the driver. Sigh...
By the way, the "Ethernet Controller" name is a red herring. It's meaningless.
