Comment 11 for bug 1630324

I've just noticed this has resolved for me. See below, the errors do not repeat and I connect to the network. However, I have recently updated my router firmware to my knowledge it's still configured like it was (40/80 Mhz channels). I'm running the same nvidia-375 that was causing errors before.
