Wireless Access Between IntelPRO 2915 A/B/G and Linksys WRT54G

Hi all, I searched without much avail, but I just purchased a slickdeal Inspiron 9300 with the 2915 card, 2ghz, 1GB of RAM, XP Pro...and I already have a Linksys WRT54G...I cannot get the 2915 and WRT54G to work with each other in WEP mode, however they can work both unsecured, and in WPA...however I need to use WEP since I also use a wirelless B Gaming Adapter through Linksys that can only do WEP...I have latest drivers and Firmware from Websites, and I also tried Intel beta firmware on the wireless card, .021 I believe...any ideas?? My Desktop with the linksys card works in all settings.
