Hi Dan, >> For the last few releases, iwlwifi has been getting consistently worse >> wrt reliability for me. [MV] Do you have an approximate idea of what release the failure started occurring? The failure mode has varied, from the chip >> just locking up with no tx/rx of packets with nothing being logged, to >> microcode warnings, and spewing 'Tx aggregation enabled' messages over >and over. [MV] I'm not sure if it is related to the problem you're seeing, but I see that you're using a 5300, so can you try to load the iwlwifi module with the following parameter and see if it helps? modprobe iwlagn bt_coex_active=0 Thanks, Meenakshi ��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
