Bug Description
Binary package hint: network-manager
I'm using Intrepid and my wireless connection (iwlagn) seems to fail intermittently for 15-30s at a time as frequently as every couple of minutes. NetworkManager doesn't report that the connection has failed and there doesn't seem to be anything of note in syslog or wpa_supplicant.log.
I have no idea where this bug could be located and I would like some help with debugging. I have experienced the bug using three difference AP. I haven't eliminated a hardware issue however, so I've only run this laptop using Intrepid. But hardware seems unlikely as the problem is alleviated by rebooting. I have experienced the bug with every Intrepid kernel that has been released thus far. The bug seems to occur mostly when the wireless network is under load. For instance, when I'm streaming videos off of Hulu.
I've looked at various bug reports (303802, 295414 - this bug seems the closest to my problem, but I'm not sure if it's the same bug).
The following displays the lag that the network experiences while watching hulu. The ping returns to normal when hulu is closed.

Try installing package "linux- backport- modules- intrepid" .. I think that's the name. Then reboot.
Also try out 9.04 live cd and see if you still see the same issue.
