Summary: I have a Dell Precision 530 that I have upgraded in every which way. I'm using WinXP and a Linksys WMP54G wireless card. I has been working fine until now. Few weeks ago I upgraded the software etc - worked fine. This week I moved. I can't get the internet to work but that's another story. Currently I will get the BSoD whenever I attach my wireless card's antenna. I've done it several times, this is the exact moment. I disconnect it and boot up - no problem. Attach antenna BSoD indicating a RT2500.sys problem. Ok - uninstalled all the software/drivers - installed original software/drivers, switched PCI slot. Same thing. Downloaded driver from Cisco's website, installed it - same thing. I'm about ready to give up on this card and plunk down $80 on an N-draft card but thought this would be a last result. Any help is appreciated. Thanks.
