I upgraded to a BEFSR41 router.. When I upgraded to the software from the linksys.com website using the onboard upgrade function, it kills the router. What gives with that ? I have done this to 3 routers by now, and it just irks me that Linksys makes available an upgrade function, and makes available upgrade firmware online, but when I have done thge process it kills the router. WHATS UP WITH THAT !!!!??
