it works. I just installed WMP11 on 3 PCs, they all work. Win7 Will install the wireless card driver by itselfe but may ask for dirver or won't connect to the wireless router. update the drive from a CD or downloawn from linksys( the laterst one is 2003), still can't connect to the router at this time. restart the PC, rollback the driver or uninstall the card ( make sure remove the driver too) from the card property. restart the PC , sit back & relax, let the Win7 install its native wireless driver, it should show as Broadcom 802.11b network adapter. sounds crazy but works for me.
