** Description changed: Dell XPS m1330 with Intel Wireless ABG uname -a: Linux ethan-XPS-M1330 3.2.0-60-lowlatency-pae #62-Ubuntu SMP PREEMPT Tue Feb 25 00:32:18 UTC 2014 i686 i686 i386 GNU/Linux what I expect: wireless connectivity to be reliable and consistent what happens instead: wireless connection cuts out, recovers, re-establishes connection. sometimes (rare) requires disabling / re-enabling via hardware or software switch. sometimes (more rare) hardware fails completely until reboot (removing and re-inserting module fails -- hardware disappears to the system until reboot). This problem will occur without a suspend / resume cycle. This problem appeared recently, within the last month or two months of kernel updates. I think the next step in debugging would be to test reliability against previous kernel versions. some relevant dmesg: keyboard: can't emulate rawmode for keycode 240 iwl3945 0000:0c:00.0: BSM uCode verification failed at addr 0x00003800+0 (of 900), is 0xffffffff, s/b 0xf802020 iwl3945 0000:0c:00.0: Unable to set up bootstrap uCode: -5 iwl3945 0000:0c:00.0: MAC is in deep sleep!.
