    Wifi usb dongle connection

    Hi,
    on my desktop computer I am using Wifi dongle, and now I noticed that after the computer boots I am not able to connect to Internet. If unplug my Wifi dongle and plug it again internet is working. Wifi dongle is fully compatible with Linux (Linksys WUSB54GC). Does anybody has the same problem?

    I never had such issue in 12.04.

    Regards.

    Hi, copy and paste this command in the terminal (ctrl+alt+t) please:
    Code:
    wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/netscript.sh && chmod +x netscript.sh && ./netscript.sh
    It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
    Thanks

    Re: Wifi usb dongle connection

    Hi, please do:
    Code:
    echo "options rt73usb nohwcrypt=1" | sudo tee /etc/modprobe.d/rt73usb.conf
    sudo modprobe -rfv rt73usb
    sudo modprobe -v rt73usb
    Then do:
    Code:
    gksudo gedit /etc/pm/power.d/wireless
    (this will create or edit a configuration file that will override the default powermanagement behavior) and enter the following:
    #!/bin/sh

    Code:
    /sbin/iwconfig wlan0 power off
    above exit0, then save gedit, close and reboot.

    Watch for errors on the first command and copy and paste for accuracy.
    Thanks
