wifi groggy after waking up

Postby ecarl65 » Wed Nov 29, 2017 11:23 am

I've done a search, and I couldn't find examples of exactly this problem. On my laptop running Linux Mint 18.2 KDE version I find that the OS successfully can sleep and wake up, which is a great start. When it comes back from sleep at first there are no connections shown, and it takes a bit to reconnect to wifi. That's all understandable in coming back from sleep. The bigger problem, however, is that even when it reconnects to wifi the connection is then unusably slow until I reboot. It says it's connected, I can even look at the traffic and every once in a while it goes from 0 B/s up and down to an occasional 1 B/s up or down. But that's as high as it goes. Trying to get to any website at all or do anything over the network is prohibitively slow. Any ideas? For what it's worth here's what I grabbed from sudo lshw in regards to networking stuff.

I have the same problem on my laptop. If that occurs I open a terminal window then tyoe:

Code: Select all

sudo service network-manager restart

You could create a desktop launcher to do this also:

Code: Select all

xterm -e sudo service network-manager restart

or whatever terminal you wish to use.
