    wireless and wired connection issue

    The issue is I have to constantly switch between the two wireless networks on campus - very annoying. The connection will still be there, but it will stop connecting to the servers. This is better than before, when I couldn't even connect to the internet. I also cannot connect via ethernet now and the option 'Auto Ethernet' is not available in the network menu.

    I am running 12.10 on a Toshiba satellite C855. I already installed the correct driver for my realtek card, but this particular issue started when I updated my kernel to get rid of the apport error. The kernel is 3.8.1-030801-generic (which is not an ubuntu kernel... even though the link I got it from was an ubuntu website). Here are the instructions I followed: http://www.liberiangeek.net/2013/03/...-ubuntu-12-10/

    Everything else is working fine. As far as I can tell it's only the wirelss/wired issue that is effecting my usage. Would this issue be solved by changing kernel to an ubuntu kernel? And if so, how would I do that?

    Re: wireless and wired connection issue

    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.

    That looks like an ubuntu kernel to me on that site.

    Thanks

    I have the wireless script. It's not not in the correct file format though. What type does it need to be to upload? and how do I convert it?

    Hi go into your home folder and post the file named netinfo.text you actually posted the script.
    Thanks

    Re: wireless and wired connection issue

    I actually typed in the command wrong the first time and it just gave me that script. Now I have netinfo.txt but it is too big to attached.

    Can I do something with pastebinit?? I'm not sure what the commands are to use the program, but I know it can save a lot of space and still get you the info you want...

    Re: wireless and wired connection issue

    According to the information you posted there is a bug in that kernel, so you would be better off trying another kernel.

    Also please note that your driver is very problematic in ubuntu, did you compile the driver you have now or is it the one that come with ubuntu?
    If you want we can try a patch for that driver that I found it will be quite a process but it may work if it does we will have learned a lot.
    Thanks

    Re: wireless and wired connection issue

    Ok, so how would I go about getting a different kernel? I used that link in my first post before, so would I just find a differentl url to a different kernel, but follow the general format of that initial article??

    I compiled it myself from the realtek site. Ubuntu didn't have a driver for my wireless card. I am willing to try and fix it, but I am a beginner. I've done a few things, like install the kernel, driver, etc and I'm starting to get the hang of some stuff, but I am by no means advanced - I'd say I'm definitely still a beginner.
