Comment 65 for bug 200509

I have the exact same experience klaxian does on comment #63 - it's when I'm pushing a lot of data or just have a lot of connections in general.

Dell m1330 w/updated Jaunty, card is intell 4965 - did not happen with intrepid. Error in dmesg;

[245265.239792] phy0: failed to restore operational channel after scan

I'm trying the workaround tardifj suggested. So far so good pulling 1.7mbit over wireless for the last 20 min.
