I am seeing this on my HP Dv4t-5100 with a Centrino Wireless-N 2230 wireless card on 12.04 with all updates current.
Some strange things happen, first, it takes a long time for the wireless to connect, then ping times to the router vary randomly from up to 1 sec down to 4 ms or so. The only thing about the wifi or intel in dmesg or the kern.log is the following : Aug 13 17:22:52 Galois kernel: [32696.796323] iwlwifi 0000:02:00.0: restoring config space at offset 0x1 (was 0x100006, writing 0x100406) Aug 13 17:22:53 Galois kernel: [32700.666488] iwlwifi 0000:02:00.0: L1 Enabled; Disabling L0S Aug 13 17:22:53 Galois kernel: [32700.673943] iwlwifi 0000:02:00.0: Radio type=0x2-0x0-0x0 Aug 13 17:28:26 Galois kernel: [33033.713985] iwlwifi 0000:02:00.0: Tx aggregation enabled on ra = 20:4e:7f:4a:80:57 tid = 0 Aug 13 17:33:06 Galois kernel: [33313.383975] iwlwifi 0000:02:00.0: Tx aggregation enabled on ra = 20:4e:7f:4a:80:57 tid = 4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/984552 Title: [8086:0085] iwlwifi intermittently losing connectivity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/984552/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
