Wireless disconnects at random after upgrade to Ubuntu 10.4
- by Daniel Elessedil Kjeserud
After upgrading my home server from Ubuntu 8.10 to 10.4 my wireless seemingly drops out, even though my IRC client keeps it's connection to the servers, so it looks like the machine just stops taking wireless requests. A ping will give a me this
Request timeout for icmp_seq 27
ping: sendto: Host is down
After a while the machine just starts responding again, without any interaction from me. When the machine comes back, this is what dmesg gives me

It's on a wireless network with WPA2, the machine worked without any problems on the same wireless network since Ubuntu 8.10 was the most resent version, and there have been no changes to my network recently. Even though the server drops out, everything else on the network keeps working like normal.
