    Re: 11.10 fresh install, wireless is very slow.

    I have the same problem. Wireless is very slow for my Dell M14x after the upgrade - it worked perfectly with 11.04.

    The link with instructions above seems to have helped a bit, but still very slow.

    Does anyone know if there is a revert - to easily restore the previous version of Ubuntu? I'm guessing not but thought I'd ask.

    I like a lot about 11.10 but without internet it is pretty useless

    My problem is related to wireless encryption. When I change WPA2 to WEP, it works fine.
    But this is not the solution.

    Hi Flashman2003, you should try b,g, speed and see if that helps, it has helped some.
    Thank you

    I've tried both b&g, no such luck. Something else that bothers me about 11.10, no Gnome classic fallback, such as the case with 11.04. I dislike unity, and I prefer the classic UI. However, the fallback mode is no longer on 11.10, and installing it gives me an incomplete Gnome desktop. It's like Ubuntu is forcing us that dislike Unity to deal with Unity or go elsewhere. So the laptop I am currently using has been reverted back to 11.04, and my primary laptop is in the process of getting Debian 6.0 installed on it. I'm glad I have separate /home partitions.

    Works fine now

    I hope the issue will be fixed before we have to use IPv6!
    It seems, that my connection got even slower after this...

    Nothing helps, not even using WEP instead of WPA/WPA2. I cannot use none encryption to test but what would be the point

    Hi Flashman2003,
    Please try this and if it helps we will need to make it permanent.
    Code:
    sudo ifconfig wlan0 down
    sudo rmmod -f iwl4965
    sudo modprobe iwl4965 11n_disable=1
    sudo ifconfig iwl4965 up
    Thank you

    I tested this on my Dell 1545 that has a Wifi Link 5100 card using the 64-bit 11.10 LiveCD, and this did do this trick. I will be testing it on my E1505 via 32-bit LiveCD as well, and will report back here.

    Hi, that will only work if the other computer is using the same driver.

    So we do need to make that permanent on at least one computer correct?
    Thank you

    The Dell 1545 uses the iwlagn driver. So easy enough I removed the iwlagn kernel module, and modprobed it back with the '11n_disable=1" option, and it works great.

    I just tested it on the E1505, that uses the iwl4965 driver, and following the same formula of removing the iwl4965 module, re-adding it via modprobe iwl4965 11n_disable=1, and this too, is now working as it should. I get proper download rates on both machines.

    Now, how would one go about making this permanent without having to reset the kernel module every time the computer is restarted?
