I recently bought an RVS4000, and unfortunately forget the "if it ain't broke, don't fix it" rule, and flashed it to the latest firmware (220.127.116.11). Subsequent to doing that, it has been inconveniently dropping the connection to my ISP and completely locking itself up to a point where a manual reboot is required, usually about 4 hours after any outgoing activity (which usually means 11pm!). Googling my way round seems to suggest that this could be a firmware problem. The accepted wisdom is that I need to use the RVS4000 Upgrade Utility to get back to a lower version, so I have downloaded and installed V1.3 from the RVS4000 support area. However, though I think I followed the instructions (including trying setting the host PC to a fixed IP address, which was not supposed to be necessary), but I am consistently getting a "Broadcast Error" message, which I am guessing means that the utility and the RVS4000 aren't talking. Is there some trick anyone is aware of to get them to talk?
