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

    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?

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

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

    So add the following lines via
    Code:
    gksudo gedit /etc/rc.local
    before "exit 0":
    Code:
    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
    Code:
    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

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

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

    Hope that helps.
