HP Stream 13 dropping WiFi in Mint 18.2

[HappyMark]

Have been using Cinnamon Mint for some time but still consider myself a newbie.

Mint was working just fine on this HP laptop, After recent update it now drops the wifi frequently. In the past I have always managed to muddle through by reading posts and adopting solutions suggested for others. This time I am stumped.

Here are the two outputs you seem to ask for:

Lets disable wifi power management

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Code: Select all

systemctl restart network-manager.service

Hi Jeremy.

Running those commands in a terminal resulted in the wireless being disconnected. It then reconnected which seemed encouraging. However. after approx 5 mins it disconnected again and the prompt to enter the wireless password appeared. Entering the correct password did not immediately result in reconnection. It took several events. Even when it did reconnect, it dropped again quite quickly.

I am writing this reply using an Edimax Network adapter to connect to the internet. This was not in the machine when I ran any of the reports sent to you. It has in the past dropped the Edimax connection as well, although at the moment it seems to be holding up.

Thanks for helping me with this.

I have just noticed that while it appears that the Edimax adapter is remaining connected, after a while you need to disconnect and reconnect again.
