    Thumbs up Solution for slow internet connection with intel 3945

    I have noticed that alot of people have been commenting that their wifi has been running extremely slow with the latest version of opensuse (11). It appears that the default driver for the intel 3945 a/b/g card iwlwifi that is installed by default is not supported in kernels 2.6.24 and up. In my case, I am running 2.6.25.5-1.1, and I assume this is the case for many of you out there as well. You will need to install the compat-wireless drivers instead.

    In order to determine your kernel version, run the following command as root in the terminal:

    Code:
    uname -a
    If you are running above 2.6.24, this is what I did to get my connection working again:

    1) download the compat-wireless and and extract the files.

    2) before compiling, you need to ensure that you have the following packages installed on your system

    Code:
    gcc
    kernel source
    kernel headers
    3) after you have installed the above packages, you can go ahead and run the following commands as root within the directory you extracted the source to:

    Code:
    #compile the drivers
    
    make
    
    # install the drivers 
    
    make install
    
    #load the drivers/unload the old drivers from the system
    
    make load
    It is important that you do not uninstall the old drivers before the installing the new wireless drivers, as doing so may cause the new drivers not to be loaded correctly.

    I hope this helps people out.

    cheers

    Thanks for that!

    I also note the compat-wireless is available as an rpm.
    Webpin - Compat-wireless rpm

    Is custom compilation necessary?

    Oops, I forgot to mention that there were binaries available! Thanks for mentioning it!

    I needed to compile my own drivers because there were none available for my particular kernel version.

    Unhappy Re: Solution for slow internet connection with intel 3945

    I think I've tried most solutions that I've found in different forums, but none of them works for me :-(

    Well, at least I'm able to see my Linksys conection now, but it doesn't work at all. It's trying to connect and then it sort of times out and I'm back to wired connection again.

    I think I've been struggling for about 3 weeks with this problem. It's sad to admit, but I guess I have to reinstall the Windows Virus again :-(

    Oh boy, I always have problems with wifi connection using linux =(

    I tried this solution, but it had no effect on my vostro 1400. I'm using adhoc with WEP encriptation, and I can find my network (I'm using gnome), but I cannot connect!

    It keeps asking me for the secret password. I use a 5 letters password, but when I set to WEP 40/128 bits ASCII (which I think is correct - the adhoc uses WinXP, and in Windows it says only WEP, doesn't say if it's hexadecimal or whatever) it can't connect and when I try again it's always reset to WEP Hexadecimal, showing 10 numbers. Is it normal?

    I everytime reset it to ASCII, but it keeps changing back to hexadecimal, no matter what.

    Never mind it was a pebkac error. I had to re-download and extract.

    Thanks

    Looks like you've got a GIT checkout... and the permissions
    (-rw-rw-rw-/drwxrwxrwx) are ... uh... 'odd'.

    You'll need to add execute privileges to the check_config.sh script... :

    cd scripts
    chmod +x check_config.sh

    That'll help for *that* file... there will likely be others.

    To be honest, I'd check how your GIT transfer is set up, since the permissions
    looks somewhat 'generic'. You're almost having to do 'trial & error' to find
    the files needing to be executable.

    In a *pinch*, you could set ALL the files to executable, but that's kinda
    weird.

    Some advice about compiling software:

    -root should really be used as a 'pop-in / pop-out' sort of usage. Download,
    untar/unzip the files and compile them as a regular user.

    tar xzf SoftwarePackage-0.1.0.tar.gz
    cd SoftwarePackage-0.1.0
    ../configure
    make

    -When the compile completes successfully... *then* install it with a simple
    sudo command

    sudo make install

    it's entirely too easy to suffer a major blonde moment and screw things up
    irreversibly. Try to stay out of root until the last possible moment. The
    sudo command is your friend.

    I once typed 'chown -R lornix:users *' while in '/' (thought I was in my home
    dir) ... aaaand then spent the rest of the evening reinstalling the system...
    since I had just made myself the owner of ALL the files on the system... and
    things don't work well after that.

    probably a stupid question...once I do a make install, and make load, is that it? Do I need to do anything to make sure the new driver boots on reboot?
