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 22.214.171.124, 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. Thanks.
