Occasionally my laptop will just loose all wifi connectivity. Running dmesg at those moments provides this output: [ 1588.714014] iwlwifi 0000:01:00.0: Error sending REMOVE_STA: enqueue_hcmd failed: -5 [ 1588.714017] iwlwifi 0000:01:00.0: Failed to remove station.

Id=1
and running sudo modprobe -r iwlwifi && sudo modprobe iwlwifi results in this:
[ 1588.961411] iwlwifi 0000:01:00.0: Failed sending remove station [ 1597.465190] Intel(R) Wireless WiFi driver for Linux [ 1597.465235] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002) [ 1597.465342] iwlwifi 0000:01:00.0: HW_REV=0xFFFFFFFF, PCI issues? [ 1597.465353] iwlwifi: probe of 0000:01:00.0 failed with error -5
I'm unsure on what this means and how to procede. Any advice?
