The brennan is now connected to a different network 192.1.63 is not even a complete address, did you mean 192.168.1.63?
The third group difference 0 and 1 is significant.
If I were you I would power off the Router, wait 30 seconds and power it up again. Then power up the B2 and from the front use the menu to "Reset WiFi" then go through the process of setting it up again as you did when you got it. You may get a New IP number make a note if it.
Then restart your PC an once connected to the WiFi try using the new IP for the Brennan to open the web UI.
