    Exclamation Ubuntu 12.04 Slow Wireless

    I've been having some issues with my wireless network adapter. I've noticed that my download speeds are incredibly slow compared to what I'm used to seeing in Windows.

    I've done some Google searches to try to determine and fix the problem, but nothing has worked thus far. I've ignored IPv6 with no change, and my adapter is currently using the RTL8192CU driver. I've had this issue in previous versions of Ubuntu as well.

    Help?

    Re: Ubuntu 12.04 Slow Wireless

    If you're downloading via Ubuntu Software Center, apt, synaptic, etc. it is probably due to the fact that today is new release date, so everyone is downloading software, doing updates, etc. The servers are probably overloaded...

    This issue has been going on for the past few days, not just today.

    Re: Ubuntu 12.04 Slow Wireless

    For the past few weeks I have had horribly slow speeds connecting to the software center as well. My connection is fine to my router, I think the servers have been bogged down for weeks now and especially today.

    I also saw somewhere else they suggested making sure that the main source of packages is in the closest location to you it may have chosen the west coast or something when you will benefit from the east coast being in MI.

    Hi, most people have not gotten that driver to work at all I believe, please post the output of:
    Code:

    Re: Ubuntu 12.04 Slow Wireless

    Dunno if it's relevant, but I'm using a RT3090 network card, and ever since I used it, I had very slow speed if using the laptop on battery power. Last month or two, it's ben fine though, I assume an update fixed that?

    Re: Ubuntu 12.04 Slow Wireless

    Hi, please do:
    Code:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    sudo modprobe -rfv ath9k
    sudo modprobe -v ath9k
    Change your wireless settings in network manager to match the screenshots.
    Thanks
