Ran the Update on my BEFSR41 4-Port Cable/DSL Router and now all I get is the error lights flashing and no internet connection. The upgrade failed to fininsh uploading to the router and quit with some kind of error. Now I don't even have any access to my router to even try to load the previous firm ware. Had to disconnect the router all togather and hook my system directly to the phone co's DSL modem to get reconnected. Guess I'll be calling Lynksys since they don't have any better documentation on "If The Script Fails" or "Troubleshooting Guide" included with this update. Apply this update at your own risk.
