Comment 11 for bug 453647

I've been dealing with the same problem.

I noticed it only happens when TKIP changes it's key (or on the rekeying interval), and it seems to cause something to crash.

^^And during these error messages the Internet is completely unresponsive until a break in the errors, which seems to be random and vary in length.

I've tried the restricted STA driver Ubuntu (am using a fresh 64bit install of karmic) found and tried compiling the lastest STA driver myself and installing it. Works just the same. I have tried wicd also, no dice.

So far my quick fix is to simply reconnect after the rekeying interval (which is set to 1 hour on my router right now). Maybe I will lengthen the interval. So basically I have a consistent connection for the length of the interval then I have to reconnect at the end of it. Think I will try AES only and see how that goes also, but I would like my computer to work with networks that use TKIP.

I have a Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) and will be looking into other drivers I can use.
