I have a BR200 Business Router setup so LAN1 is ports 1, 2 and 3 with and internet works fine with these ports. I have port 4 setup as VLAN10 with an IP structure of 192.168.10.1. Internet was working fine on port 4 for months, but all of a sudden stopped working. None of the settings on the router changed. On the dashboard I can't even see LAN2, for port 4.
Kindly double check the physical connections on the BR200.
It would be best that you post an image of your detailed network diagram as this will help other community members who will chime in and make suggestions.
What is the current firmware version of the BR200?
