Since 14.04 Upgrade Wifi does not connect after suspend, ralink RT3290

[arehragout]

Hi I have a Ralink RT3290 wireless card,
in 13.10 everything worked well, now in 14.04 after a Suspend/Hibernate action the Wifi tries over and over to connect but fails.

SUSPEND_MODULES="rt2800pci" in etc/pm/config.d/config

doesn't help.

BTW bluetooth doesn't work either!

Any suggestions?

Thanks!!

Tried this driver?

http://forum.ubuntuusers.de/topic/na.../#post-5641297

If it works change the settings in your etc/pm/config.d/config. BTW: Is the file set to executable?

sudo chmod +x /etc/pm/config.d/config

same story with ath9k dell inspiron
work again only after shutdown
reboot not help

[praseodym]

So add the following lines via

gksudo gedit /etc/rc.local

before "exit 0":

modprobe -r ath9k
sleep 5
modprobe ath9k

Reboot.

tried the last idea with my rt2800pci driver, interestingly this showed the same behaviour, which i previously had only after suspend, now already after boot - so no wireless at all.

yes, my config file is executable.

i'll try the driver from first reply, is there any danger in doing so?

thanks for your quick response!

No, if its compiling (at all) and not working you can easily uninstall it via

sudo dkms remove -m Ralink_3290sta -v 2.6.0.0 --all
sudo rm -r /usr/src/Ralink_3290sta-2.6.0.0
sudo rm /etc/modprobe.d/blacklist-rt2800pci.conf

So add the following lines via

gksudo gedit /etc/rc.local

before "exit 0":

modprobe -r ath9k
sleep 5
modprobe ath9k

Reboot.

this not helped
sometimes shutdown not helped too
work again after long switch off

Had the same problem. In my case, the problem was double:

1. the network would not come up at all after suspend;
2. after a "sudo restart network-manager", the network would come up again, but the wifi wouldn't connect to my network.

I found a permanent and complete solution based both on this and that, which is:

sudo touch /etc/pm/sleep.d/wakenet.sh

sudo chmod +x /etc/pm/sleep.d/wakenet.sh

sudo gedit /etc/pm/sleep.d/wakenet.sh

Insert the following lines:

#!/bin/bash
case "$1" in
thaw|resume)
nmcli nm sleep false
pkill -f wpa_supplicant
;;
*)
;;
esac
exit $?

And then save.

Hope that helps.
