    Wireless problems in 12.04, though I have full signal

    Alright so I'm a bit new to ubuntu/linux in general, and ever since I switched from windows 7 I haven't had the greatest time with the internet. I'm connected with high signal strengths, but a lot of the pages I go to won't load. I'm also not able to download and install programs at the moment (says something about not being able to fetch something).

    I've been reading forums all night, and the only thing I've found to help out was disabling IPv6. It made more sites work, but I'm still having a lot of problems.

    I have a Toshiba Satellite a505. I'm not sure at the moment exactly what a505 it is. My router is an XFINITY Wireless Gateway TG852G. I can't use a wired connection at the moment- no ethernet cable in the house right now.

    I've used the network manager tool and it came up with this:

    Re: Wireless problems in 12.04, though I have full signal

    I'm not familiar with that chip set. It would be preferable to 'fix' the existing driver. If you don't get a better reply in a reasonable time, you could try downloading and installing Realtek's driver.

    http://www.realtek.com.tw/downloads/...&GetDown=false

    I've used Realtek's drivers for an 8188Cus device and the install script worked fine. Do be aware with this solution that a kernel upgrade will 'kill' the adapter. The fix is easy - rerun the installer script. But do keep the download where you can find it again. You may or may not have to blacklist the current driver. The current driver's name can be found by running "lsmod" in a terminal.

    For some reason that site didn't work for me. Like I was able to get to it, but when I clicked on the mirror to get the driver it prompted me to enter a password I don't have.

    Try again. I have downloaded from their site many times and have even built drivers for your exact chipset from Realtek's site. I tried again now. No password asked.

    Try downloading on another computer to a flash drive and copy the zip file over, if need be.

    FYI, you may have to blacklist the existing 8191/8192 driver before installing the new one.

    Yeah it's still doing the same thing. It tells me the frameload was interrupted, and then firefox opens (I'm using midori) and prompts me for the password. It specifically says "Enter password for WebUser on ftp://209.222.7.36"

    As far as downloading on another computer, that will take maybe a day or so. There aren't any other computers in the house, but I can get a friend to do it for me.

    Thanks for helping me, by the way. Sorry for the lack of know how.

    EDIT: It's starting to load sites better, but a lot of the time midori isn't able to resolve the host name.

    Okay so I have the driver. But I'm not sure how to install. I know how to blacklist the other driver, but I can't find anything on installing the new one.

    Again, sorry for the lack of know how.

    Unzip the downloaded file. Then open a terminal and navigate (cd) to the directory where it was all unzipped.

    I think you have to make the installer executable:

    sudo chmod 755 ./install.sh

    Then, just type

    sudo ./install.sh

    You may need to add the module name to the file /etc/modules so it gets loaded each time at boot.

    It says no such directory when I use sudo chmod 755 ./install.sh


    There's a compat-install in one of the folders. Would that do anything or should I leave it alone?

    Sorry - this driver is different from the one for my Realtek module. I just downloaded and looked at it.

    There is a "readme" file in the main directory, and it gives you these instructions for 12.04 that basically boil down to:

    sudo make
    sudo make install

    (reboot the computer)

    The "compat-install.sh" script is for older kernels.

    Okay, well now I believe it is installed. However, firefox is still having trouble finding sites. Midori is doing better, but I really want to use firefox. Here is the results of checks and stuff.
