I too, have this problem. I get about 90 seconds of wifi every two minutes. I'm currently tethering via USB to my mobile phone which is then connected to the wifi so I can use the Internet properly on this laptop. A dangerous game, because if the wifi drops out on the phone I start using my 3G data plan.
I'm using an 802.11n wireless router, and a Thinkpad X200s with the Intel 5100. I only just upgraded to 11.04, the wireless worked properly prior to my upgrade to 11.04. During my downtime I get output like: [10108.754334] iwlagn 0000:03:00.0: Aggregation not enabled for tid 0 because load = 0 [10171.046204] iwlagn 0000:03:00.0: Aggregation not enabled for tid 0 because load = 0 [10177.214373] iwlagn 0000:03:00.0: iwlagn_tx_agg_start on ra = 00:22:75:f2:b0:43 tid = 0 [10181.688873] iwlagn 0000:03:00.0: low ack count detected, restart firmware [10181.688884] iwlagn 0000:03:00.0: On demand firmware reload [10181.722312] iwlagn 0000:03:00.0: Stopping AGG while state not ON or starting [10181.722322] iwlagn 0000:03:00.0: queue number out of range: 0, must be 10 to 19 [10184.404182] iwlagn 0000:03:00.0: iwlagn_tx_agg_start on ra = 00:22:75:f2:b0:43 tid = 0 [10189.368725] iwlagn 0000:03:00.0: low ack count detected, restart firmware [10189.368735] iwlagn 0000:03:00.0: On demand firmware reload [10189.400582] iwlagn 0000:03:00.0: Stopping AGG while state not ON or starting [10189.400592] iwlagn 0000:03:00.0: queue number out of range: 0, must be 10 to 19 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/575492 Title: Intel 5100 AGN wireless connection bug -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
