    Wifi randomly disconnects and reconnects on Windows 8 laptop with Ubuntu 12.10

    I have a Lenovo Windows 8 laptop. I started get bored with Windows 8 and much more interested in Ubuntu again and now Ubuntu Touch. Anyways, long story short. I downloaded Ubuntu 12.10 on a DVD to try it out first then as I noticed how much more faster Ubuntu is on this laptop than Windows 8 itself, and all the open-sourced goodness, I installed Ubuntu 12.10 alongside- WIndows 8. I may installed Ubuntu 12.10 solely on here too if all goes well. Only issue is that my Wifi is randomly cutting off when the Wifi is still on in the house but I get the notification above saying it's disconnected etc, then reconnects. While typing this post, it's disconnected 5 times already. Please help me! Thanks!

    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/wireless_script && chmod +x wireless_script && ./wireless_script
    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, click on the paper clip and attach the netinfo.txt file.

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

    Please do:
    Code:
    echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
    sudo modprobe -rfv ath9k
    sudo modprobe -v ath9k
    Let us know if that helps.

    Part of the informaton in that file is missing and couple of things did not look right.
    Thanks

    well I tried to run the first text into the terminal again and I got another netinfo file that was larger but it won't let me upload to attach it. And tried the 2nd text in the terminal and I got an error saying

    tee: invalid option --'r'
    Try 'tee --help' for more info

    Please just copy and paste the commands one line at a time into the terminal for accuracy, and just post the contents of the file here.
    Thanks

    Please use code tags - if you are using New Reply button - highlight text and use the # button in the text box header.

    If using Quick Reply then [code] at the beginning and [/code] at the end.

    This is a newbie question but how do you copy and paste into and from a terminal? I tried with the basic keyboard shortcuts but won't work. I understand the rest of what you requested regarding the code. Thanks!

    Hey, sorry it's taken so long. It's just frustrating that everytime I try to get something done, I get disconnected. I even managed to shrink the partition with Windows 8 and reinstalled Ubuntu 13.04 into a much larger partition to maybe help.

    I just ran the 3 lines of code you gave me above into the Terminal and Wi-fi seems more stabel for the moment. It's been about 5 minutes and no disconnect, which is rare lately lol. I'll let you know if anything else transpires. If you want me to I can paste in code form, the netinfo.txt as well, which I ran before the 3 lines of code.
