    Got myself one of these routers a little while ago, its working great...only thing is it appears to run only at 54mbps...the box says 125mbps is possible...i mean hey i dont expect it maxxed out but more than standard 801.11g would be nice.

    I'm not a whizz kid with routers ...any suggestions about something real stupid i am doing ..or not doing would be greatly appreciated.

    I'm using a WPC54GX wireless pcmcia card to connect to it..i assume that should work ok its meant to run at 108mbps.

    Any help would be great.

    125mbps is a myth. a normal 54g connection you will get approx 20-25mbps. on a speedbooster/Afterburner connection you'll get approx 28-32Mbps. adding extra wireless clients and the bandwidth will be "shared, thus bringing those speeds down.

    hmm, i'm not sure if there has been a misunderstanding here. when i talk about speeds, i mean, my wireless card connects and displays connected at 54mbps...signal very good or excellent. i was expecting it to say connected at 108mbps as thats what the card is capable of according to the packaging.....

    The speed booster only works with Windows 2000 and XP with the driver for the wireless card. And if I remember correctly, the Speed booster is brand specific. Which means that if you have a wifi card from Belkin and you have a Linksys wireless router, they may not work together. Oh they will communicate ok with 802.11 G but the speed booster may not work.

    I'm afraid you are not going to get any advantage from Linksys Speedbooster because 108 means "Atheros SuperG", 125 = "Broadcom Afterburner", these are incompatible wireless G extensions - but don't worry you are not missing out on much.

    Here's a simple comparison, also look at tomsnetworking guides for actual performance tests

    in addition, even in othe most perfect environments, if you have even ONE client connected to the network that doesn't support speedbooster, the entire wireless network gets cut down to the fastest speed the slowest client supports..

    Here's you problem in a nutshell.

    You have the WRT54GS router that uses "SpeedBooster" branded technology.
    You have the WPC54GX adapter that uses "SRX" branded technology.

    The two families will work with one another but without any of their enhancements. In otherwords, you either need to switch to a router from the SRX family (WRT54GX) or get a wireless adapter that is part of the SpeedBooster family (WPC54GS) to see the mythical "connected at 108mbps." Not that it makes a big difference mind you as like what was previously mentioned, the real world throughput is a mere fraction as to what that "connected at" rate is.
