WMP54G lag issues...

    I have a WMP54G that I recently installed in my desktop. The card apparently has a problem communicating with my router (WRT54G). If I do ping -t (router), it will respond with 1ms - 3ms. However, every few minutes I get some insane response of 1300 or so. Have the same problem when it's installed on another computer. If the same computers are hardwired, they have no problem. I have a laptop with a built-in wireless card that does not have the same problem. The driver is, which is the latest offered from Linksys. I've tried toying with everything Linksys told me until finally the guy said, we've run out of options. I bought a new WMP54G (should have gotten a GS, methinks) and still have the exact same problem. I've tried tinkering with settings - fragment threshold, RTS threshold, all of it. If anyone has any suggestions, please help.

    i have one too and it's a version 4 and my driver version is, it's not on the linksys site for some reason, but i got it via the windows update website, so if you have windows do windows update and see if it offers an updated driver from version to

    As always: USE THE OFFICIAL BROADCOM DRIVERS! Link to them to be found in this forum!

    I'm sure your right about these drivers. So I didn't manage to install those drivers. Windows allways detect the standard linksys drivers.
    What's the way to update drivers with broadcom drivers ?

    Hi All!

    Be careful with drivers for the wmp54g.
    There are several hardware versions...

    WMP54g v2 is equipped with a Broadcom chipset, so use the linksys broadcom driver instead.
    I think there is no way to use the - more recent -official broadcom drivers.
    I never could get a wmp54g v2 working on a normal way this newer Broadcom drivers... Signal strength wint down with 50%, no stability. Anyone could find a solution to use the newer Broadcom drivers? please tell us how!
    I use the official <linksys drivers instead.

    The newer version (v4) uses a Ralink-chipset. So do not use the broadcom drivers instead! This is asking for trouble.
    The wmp54g v4 you can easy use with the newer Ralink-drivers.
    So go to www.ralinktech.com and get the newest drivers.
    Just install this package. You will see that the newest driver will not be recognised by the wmp54g v4 but this is not a problem...
    Then go to controlpanel / system / hardware (in windows) and change the driver for your card manually (do not let windows search for it!).
    The right drivers are located in c:\program files\ralink\rt2500 wireless lan card/installer.

    I hope this helps.

    Hi, i always thought that my Wap54g is the problem, because i wasn't able to test it with another adapter.

    With the ping command i have exactly the same results, but the ralinktech drivers didn't changed anything.

    other ideas?

    i dunno which versions the others have but me 4

    edit: i think i found an answer for the problem with hardware version 4
    somone in another forum said that you have to disable the WZC tool. Because it searches always wireless networks, and this could be the reason. So i did it (disabled the service with msconfig). I had to reinstall the original wmp54g drivers with it's monitor.

    Now it seems that these lags don't appear anymore, but i hadn't the time to test it by hard, hopefully it is the ANSWER to this problem ^^

    i used to have these lag issues too with my WMP54G version 4. But since i switched from using the Windows Wireless Zero configuration to the linksys wireless network monitor, those lag spikes don't appear anymore. So, the bottom line: go to the linksys site and download the latest available driver and monitor for your adapter and use them. It worked for me. :)

    Could all of you guys saying that the problem is solved please do a "ping -t" or whatever your router ip is ?
    Just leave it pinging for at least 2 mins and then check if you don't have ANY high ping value.

    Also, could any of you provide me a way of finding out which Version of the WMP54G i have please ?

    Thanks a lot.

    Look at the label on the WMP54G specifically the FCC ID if it says WMP54GV2 is is a version 2.0 and WMP54GV4 it is a version 4.0 the version 4.0 has a thinner housing and you can see one on the Linksys site or you can go to the FCC site and put in the prefix Q87 and do a generic search at https://gullfoss2.fcc.gov/prod/oet/cf/eas/reports/GenericSearch.cfm

    Thanks for that.

    I finnaly got it fixed by disabling the WZC, but had to download the Ralink drivers cause the Linksys drivers game me random disconects.

    Working great now :)
