This past weekend I upgraded my Acer Aspire notebook to 8.10. For some
reason, I can't get the wireless working.
The 4520 has an Atheros wireless chipset. lspci:
07:00.0 Ethernet controller: Atheros Communications Inc. AR242x
802.11abg Wireless PCI Express Adapter (rev 01)
Following the release notes, I installed
“linux-backports-modules-2.6.27-7-generic” which I understand contains
the ath5k module that should support the AR242x chipset.
However, I can't seem to switch the WiFi on. Pressing the WiFi button
has no effect; no LED is switched on or off. Googling the issue, I
encountered this post which alludes to the problem:
The writer suggests that it might be necessary to boot Windows (!) to
switch the wireless on. Unfortunately, I erased Vista when I bought the
FWIW, with my previous Aspire, of which the wireless worked flawless
under Ubuntu, the WiFi interface was activated by default at boot time;
a bright orange LED indicated this.
Any one have any ideas for me?
