I had a number of Network Everywhere /Linksys NWR04B B Routers. No trouble until the latest batch of routers which a have a newer firmware update. ( v 1/20D1220) which seems to be buggy ( or at least in my limited experience). Anyone know where I can obtain an older version of the firmware ? Will the router firmware upgrade allow me to install an older version over a newer one ? If not is there any way of installing a Linksys file for a similar product ???
