@ b*cat:
Configured everything exactly as you advised, have been accessing the router on my LAN with IP add. of 192.168.0.200, results as follows:
After procedure, could not access router on IP add. 192.168.1.1, ie., default.
Router accessed on IP add. 192.168.0.200 (after changing PC to static IPv4 add. of 192.168.0.100)
Nothing in the router config. had changed, admin & supervisor access PW's were the same as previous.
Repeated exercise to ensure repeatability, results were the same.
So, short answer to " did you see a FW update page ? " is no.
Hope this helps.
