    As a lot of you guys probably know I am having wifi speed problems using Ubuntu. I have posted before I have not got very much help at all therefor I am experimenting.... :/ I raised my MTU to 10000(which is my max) and it seems to be helping a little bit. Is that ok to raise it so high? Also, should I mess with IPv4 or IPv6 settings? Should my "mode" be infrastructure or add hoc? Is WPA & WPA2 Personal security ok?

    I know very little in this area, but since no one else is answering, I'll relate what has worked for me in the past.

    Disable IPv6
    check antenna (of your wirless router) position
    check for cell phones, wirless phones, or other electronics that may be interfering with your signal
    check to make sure you have the correct driver installed

    Some people have reported issues with the 11.04 and 11.10 version of Ubuntu, so if all else fails, try the 10.04 LTS version, or another distro.

    Each piece of equipment has a module that tells computer how to interpret the signals from that equipment. In wireless, this would be something like the bw43 driver or rt3070 driver. Go to the wireless forum and follow the instructions at the top "wireless setup start here", then post the results. I'm not good at interpreting the output, but we have several members who can tell you which drivers are installed, and if they are the right ones.
