    After fresh 18.04 install, wifi performance was very poor. This seems to fix the issue:
    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 11n_disable=1
    This will only temporarily fix the issue. To make the changes persist:
    echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf

    Hope this helps!

    Great... thinking of buying the 15 version for Ubuntu/CUDA and Machine Learning tasks...
    Do you have any issues with Ubuntu? Thanks!!!

    That's fantastic. I've been struggling with wifi with some routers with my late 2016 Blade. That seems to have fixed to issue. Thank you.

    Spoke too soon there... when I added that line to iwlwifi.conf things broke down pretty bad. The strange thing is that I only get problems with certain routers... namely the one I have at home. When I'm on work or connected to another router wifi works fine.
