Ubuntu

on awake from suspend pc wifi connection not re-established

Asked by Peter Jordan

I am using 14.04 LTS 32 bit on my PC. Settings are -suspend after 10 minutes inaction. Am not sure what Suspend is meant to mean in terms of Ubuntu,( moving the mouse does not awaken it as in windows). Pc switches down. Have to press start button to come out of suspend.

All works Fine except my Wi Fi connection.

To re-establish a connection to my router I have to physically unplug my usb wifi connector and then re plug it in. It will only then restore the wifi connection. Surely this is not correct. .

should mouse movement bring the pc out of suspend or is it correct that I have to press the start button.
Is my wifi problem a bug as it only occurs on wake from suspend.
How do I overcome this problem which only occurs coming out of suspend

Try the below 2 commands:

sudo cp /etc/pm/config.d/config /etc/pm/config.d/config_20150917

echo "SUSPEND_MODULES=r8712u" | sudo tee -a /etc/pm/config.d/config > /dev/null

Reboot, then test.
