    Unhappy Wirless rt2500pci very slow

    Hi, I just installed Ubuntu 8.04 and ran my wireless and noticed its extremely slow. On windows I get 90% signal strength, on Ubuntu I get 48% signal strength. That automatically means something is wrong. I have the rt2500pci drivers on because I did "lsmod" and saw them there, but is there something else I need to do to set them up properly. I need this problem fixed right away for school and business purposes.

    Re: Wirless rt2500pci very slow

    My problem with this driver in 8.10 (kernel 2.6.27-7) is that the
    driver get fixed to 1 Mb instead of 54 Mbit.

    wlan0 IEEE 802.11bg ESSID:"AirWolff"
    Mode:Managed Frequency:2.437 GHz Access Point: 00:1F:C6:78:11:13
    Bit Rate=1 Mb/s Tx-Power=27 dBm
    Retry min limit:7 RTS thrff Fragment thr=2352 B
    Power Managementff
    Link Quality=52/100 Signal level:-48 dBm
    Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0


    after i do 'iwconfig wlan0 rate 54M' i get this:

    wlan0 IEEE 802.11bg ESSID:"AirWolff"
    Mode:Managed Frequency:2.437 GHz Access Point: 00:1F:C6:78:11:13

    Re: Wirless rt2500pci very slow

    I have just installed Hardy on my old laptop that has a card with the rt2500 chipset and i found that building and installing the latest driver daily build from serial monkey the signal seemed much more stable.

    I had to blacklist rt2500pci.

    I am using WPA-PSK at home.

    I also built and installed the latest Rutilt wireless manager after uninstalling gnome network manager.

    Although my experience with wifi is limited to this one card I do find that the wireless range is not as far as under MS XP but it functions ok.

    Doug.
