I enabled bridge mode on the Surfbeam 2 since the installer said that the ARIA routers are not available in my area. When in bridge mode does the diagnostic page viasatmodem.com (192.168.100.1) still work or is it at a different IP address to access the modem?
Are you using your own router? Apparently, your modem is not in bridge mode now.
If you enabled bridge mode and have no router connected to the modem, then you’ll not be able to access the configuration page (first you need to connect a router, or reset the modem).
The modem is in bridge mode
I am able to access the moem webUI by going to https://192.168.100.1/?page=modemStatus
