I've been having a problem with the wireless speed of my WCG200. About once every week and a half or so, my transfer rate drops from 54mbs down to 1mbs or less and my network essentially shuts down. Has anyone else noticed this behavior. Notes: 1. I have seen this while having only 1 (and in some cases 0) computes on my network running. 2. I get fragmented packet entries in the log file. I seem to be getting port scanned every two to three hours. 3. When this happens I usually clear the log, and reboot the router and service improves back to 54mbs. Hadware version: 1.2b Firmware version: 18.104.22.168.4-1104 Is there a firmware upgrade available?
