    Try installing "LinSSID" and search for free channels. Channel 6 is very busy

    I will do that and take a look. One thing to consider is that I have no issues when running Windows 7 on that laptop (it's dual boot). Also, I was going to try and see how it works when connecting to a different router at my in-laws, I just haven't been able to get around to it. There will be no other interference there...

    So I installed LinSSID. It appears channel 1 is the busiest channel and channels 6 and 11 are roughly equivalent. Right now I have it set back at channel 1, but I will probably change it to 11. Even on the busiest channel, Windows gets 30 MB/s and Linux gets 0.5 MB/s. I can try connecting to a different router this evening and at least see if the router might be the issue.

    Try Wicd instead:
    Code:
    wget http://www.elektronenblitz63.de/download/wicd-1.6.x_addon01441.tar.gz
    sudo apt-get install --reinstall wicd
    tar xvf wicd-1.6.x_addon01441.tar.gz
    cd wicd-1.6.x_addon01441
    sudo ./install_wicd_addon
    sudo service network-manager stop
    sudo killall wpa_supplicant
    sudo service wicd restart

    Ok, I've tried a couple of things. Before performing the commands you suggest above, I tried connecting to another wireless router. This seemed to go much better as I was able to get 17 MB/s download and 3 MB/s upload. I don't have that connection information but will try it again another day when I have a chance. After that, I came home and tried the commands above. I had no issues until I got to the last 3 commands. After each one I got the following response:

    sudo: unable to resolve host z757: Connection timed out

    At the end, I had no wireless network connection at all. I tried rebooting and the wireless network was available again but was very slow. I tried repeating the commands, but then I lose my network again. AT this point I opened the WICD network manager and tried connecting through the program. It says that I connected, but I did not have internet access. So, after all of that, if I restart the computer, it goes back to being able to connect at the original slow speed.

    Just bumping again. I will be able to go try the other wireless router this weekend and get a print out of what goes on when I connect to that one.

    Change the encryption mode to WPA2-AES (CCMP), not mixed mode WPA/WPA2 (without TKIP)

    I changed my router to WPA2 and I changed in WICD also. No improvement. Although, my network manager says WPA/WPA2.

    I installed the drivers for a usb wireless adapter. I was able to get that working, but the slowness issue continued. So, I think that rules out my wireless card. I will post my information this evening when I am at home. Is it possible that there is an incompatibility with my router? When I go to another house and use a different router, it seems to work ok. I guess I need to compile statistics for all of these different cases and find out what is different! If only I had infinite time... Thanks for all the help so far. I have really learned a lot and I am very appreciative that you guys are willing to take the time to help new users like myself!
