    I have a WRT54G v1.0. I'm running the latest rev of the Linksys firmware as of last week.

    I had the system running just fine with 64bit WEP and disabled SSID.

    I've decided to become paranoid, so I upgraded XP to get WPA and I enabled WPA-TKIP. Now my wireless connectivity drops frequently and the only way I've been able to get it back up is to go into the web interface and tweak some setting (heck, just resetting the TKIP key to the same value works).

    But at some point later it drops again....grumble, grumble.

    I am open to the idea of running third-party firmware if it is likely to help or at least help me get some type of feedback as to where the problem might lie.

    Anyone have some tips/pointers?

    I have the same problem running WPA. The Wireless connection just freezes. A disconnect - connect in Windows XP resolves the problem most off the time. Sometimes I get a "wireless connection unavailable" and have to reset the wrt54g, but I thinks that's a bug in Satori (from sveasoft) firmware. As u see, custum firmware doesn't solve the problem, that's because the wireless driver from broadcom is closed source. We will have to wait until Linksys or Broadcom fixes this bug...

    Thought this maybe of use if your wireless connections are flakey.

    Use channel 1 6 or 11 first of all (11 being prefered)

    if your wireless devices are all G then if possible set your router to G only. if not set Wireless to B only (inless u have B and G devices)

    If you have just one or two clients enabling frameburst will help. Make sure CTS is disabled.

    Beacon Interval can also be lowered to say 50 and may help The default value is 100. Enter a value between 1 and 65,535 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network


    for best security enable WPA-PSK and AES if possible. Both Router and Devices have to support them though.

    MAC Filtering will help as well. setting your router to only accept mac addresses of Your devices only.

    Disabling SSID will also help anyone trying to hack into your wireless network.

    Thanks for the replies.

    I already had channel 11, beacon set to 50.

    I have now enabled frameburst (two clients only right now, on an extremely rare occasion three). CTS is disabled.

    I have moved to AES from TPIK. I have not enabled MAC filtering yet, but will consider it. SSID broadcast was disabled before I hooked the device up to my LAN in the first place.

    ...anyways, I guess we're all awaiting driver updates from broadcom...the worst scenario as the problem is "out of our hands" (or so it appears).

    Will post back with my results after a bit of testing.

    Thanks again!

    how good is the signal reception? perhaps boosting the signal may help.

    Signal has always been "excellent". I'm at most one floor directly below the wrt54g, so I can't see this as a problem.

    Thing is, I had no problems with drops at all when I wasn't using WPA. I think I was using 64-bit WEP.

    Now that I've gone to WPA I get these drops (though no drops since my previous post...but I haven't been banging on it hard).

    El-crapino. Wouldn't you freakin' know it...the IBM T30's come with the "High Rate Wireless LAN Mini PCI with Modem II" and after upgrading latest drivers, etc...I don't have "AES" as an option under WPA.

    Looks like I might have to go with another security configuration...

    I'm downloading a newer IBM "access connections" utility to see if it increases my choices.
