Title:
iwl3945 wireless connection becomes unreliable
Status in linux package in Ubuntu:
Incomplete
Bug description:
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:
