I have a Linksys BEFW11S4 WIRELESS b ROUTER and I can't install it because I have lost the installation wizard disk. Can you copy your disk and send it to me or loan me your disk? I have tried many customer service no. without much help. They want to sell me tech support for more than the cost of one. Perhaps the disk for another model no. would suffice? what do you think? Can you help? Thanks, firstname.lastname@example.org.
