    [ask] had to reinstall usb wifi driver every reboot

    I got Edimax EW-7811Un usb wifi adapter, I just upgraded to the latest driver from realtek website, I downloaded the driver file RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622 from realtek website, and I ran "sudo bash install.sh", then I ran "sudo gedit /etc/modprobe.d/blacklist.conf" and put the line "blacklist rtl8192cu"

    It installed and working fine, but the weird thing is, on every reboot the device is missing and I had to reinstall it, so the device can be detected and used

    Is there a solution for this ?



    Thanks

    You can use script which will re-eject device.
    But you should better try to find solution from internet.

    If it's not getting loaded automatically, you may need to add the module to /etc/modules so that it's loaded at boot time

    NB I'm guessing you built the 8192cu module from Realtek - adjust the module name as appropriate if that is not the case

    Code:
    echo "8192cu" | sudo tee -a /etc/modules
    If you're not sure which module the device is using you can use

    Code:
    nm-tool | grep 'Driver'

    I had pretty much the same problem, I had to re-install the realtek drivers after each restard to get the wireless network to run at normal speed. This solved my problem, I was just going to make a post about it, thanks alot. The driver name for me was "rtl8192cu"

    many thanks, this also resolved my problem. Although nm-tool incorrectly identified my driver as rtl8192cu when infact its 8192cu

    $ nm-tool | grep 'Driver'
    Driver: e100
    Driver: rtl8192cu

    $ lsmod | grep 8192
    8192cu 502485 0
