    Rt2800 Wireless disconnecting frequently

    My wireless card disconnects frequently and sometimes it won't even connect at all. I've googled the card and the driver and it looks like others are having similar issues as well.

    My lspci | grep -i network is as follows
    02:01.0 Network controller: RaLink RT2800 802.11n PCI
    Under iwconfig, it's identified as wlan0, and I'm running kernel x86_64

    same problem. I am running 10.04 LTS. It worked fine with 9.04 and 9.10.

    The problem may be specific to AES encryption. I've changed my encryption type to TKIP and haven't have any issues (16 hours up so far).

    I've also seen reference to conflicts between two modules doing the same job. run:

    lsmod | grep rt2
    Either rt2800pci should be present, or rt2860sta. Not both.

    Note: I'm a debian user, so the solution for me may not apply to Ubuntu, but I saw this while I was digging and thought I'd offer the solutions I found anyway.

    Same problem here. After upgrading from 9 to 10.04 (using the same wireless card)the card does not work any more. It finds the network, but then keeps prompting me for the password (I have WPA & WPA2 enabled) without connecting successfully. It has, however, connected once since the upgrade.

    output from various commands follows.


    llist@MusicPc:~$ lsmod | grep rt2
    rt2860sta 542482 0

    llist@MusicPc:~$ iwconfig
    lo no wireless extensions.
