Description of problem: Establishment of the very slow wifi connection to the module iwlwifi since moving to kernel 4.4. The problem is not present with old kernel like 4.1 Hardware is : Lenovo Thinkpad T410S with the following wifi module 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) Subsystem: Intel Corporation Centrino Advanced-N 6200 2x2 AGN Kernel driver in use: iwlwifi Kernel modules: iwlwifi At the startup, we can see in the dmesg file, the following errors [8.554303] iwlwifi 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control [ 8.568225] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-6000-6.ucode failed with error -2 [ 8.568230] iwlwifi 0000:03:00.0: Falling back to user helper and a few later, the second part [ 19.658175] xt_addrtype: ipv6 does not support BROADCAST matching [ 61.917777] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun [ 61.918199] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun [ 68.568777] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-6000-5.ucode failed with error -2 [ 68.568784] iwlwifi 0000:03:00.0: Falling back to user helper Note we have found a workaround. Problem disappear when we enter the two following command. "cd /lib/firmware ln -s iwlwifi-6000-4.ucode iwlwifi-6000-6.ucode" Version-Release number of selected component (if applicable): Kernel 4.4.xx How reproducible: Always Steps to Reproduce: 1. Boot Mageia with a kernel 4.4 2. See the error messages in the dmeg.log 3.
