    Re: WiFi often disconnects

    But it should be in this one, right? →→→ http://kernel.ubuntu.com/~kernel-ppa...e/v3.10-saucy/
    I installed that but, as you noticed, I still had disconnection issues from 3.2 to 3.10. Now everything seems to work better with 3.8 + 3.10 backport.

    Re: WiFi often disconnects

    The backport drivers are not installed when you install ubuntu they are not part of the kernel but you use to be able to install them with software center, since 13.04 it was removed from the repository.

    So the driver you installed is not the same that comes with ubuntu.

    Re: WiFi often disconnects

    So, a backport is a backport, I won't find it in 3.10 as well.
    Thank you very much. I'll keep you updated if something new is going to occur. Thank you again.

    Re: WiFi often disconnects

    I definitely spoke too soon :'(
    I had the usual disconnection and can't connect again.

    Didn't change anything from last time.

    I was thinking that it would be fantastic to have the router to reboot itself every x minutes automatically, but I think this is impossible. It's easier to have it if I was always connected, but I'm not.

    Re: WiFi often disconnects

    Hi, I doubt it is the same issue because it worked for five days.

    Did you install any updates?
    Did you look at the updates to see what was being updated?
    Did your computer lose its power supply?
    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/wireless_script && chmod +x wireless_script && ./wireless_script
    It will download a script and create a file named wireless-info.tar.gz 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, click on the paper clip and attach the wireless-info.tar.gz file as a zip file.

    If you do not have ethernet either then follow the directions at this link for running the script without internet.

    Post Re: WiFi often disconnects

    In these days disconnected and reconnected immediately, so I thought it was solved. Maybe I've only been lucky?
    Yeah, in these day I installed Raring latest updates: compiz. I didn't upgrade the kernel though.

    The result of the script is attached to this post.
