Bug Description
Was adding comments to Bug #710738 until I was advised my situation is different. Before that, I thought I was seeing Bug #714300 but my symptoms aren't quite right for that either.
Laptop's wireless worked very well under Ubuntu 10.04 Lucid, and Ubuntu 10.10 Maverick, but on upgrade to Ubuntu 11.04 Natty over the weekend, the wireless seemed non-functional.
As it turns out it would sometimes connect after a really long delay. Adding a file containing one line:
/etc/modprobe.
options ath5k nowhcrypt=1
seems to make the connection connect somewhat more reliably, but it still often takes hundreds of seconds before wireless ESSIDs even start to appear in network manager. Sometimes, however, the connection will start coming up immediately on reboot.
In trying to debug this I discovered that the wireless button and other things that I might expect to see from acer-wmi are not appearing. I manually modprobed acer-wmi with no change visible to the lsinput utility.
The dmesg and other files attached to this bug are probably the "best case" scenario where the wireless came up pretty quickly after I booted. I will boot again and collect some other info that might be relevant when the wireless doesn't work.

well now I can't even make it FAIL reliably! On this boot the wireless again came up pretty quickly.
When it is failing I get lots of timeouts in syslog. Usually network manager doesn't even try for several minutes and then when it does, there will be dozens of failures. In this case it only failed for two sets of three tries. Which to me is wonderful...
