TLDR; ssh into your edge router and restart the failed interface using: “disconnect interface <interface name>”
“connect interface <interface name>”
Overall I really like my EdgeRouter X from Ubiquiti, the price point seems really good at about $60. The feature set is nice and I like the UI features and graphs. I have two ISP connections in my house to avoid outages. Something that I want to avoid now that I work from home all the time.
Anyway, on occasion, I have found that my edge router reports my DSL interface as down but when checking the web UI I don’t see an option to restart, disable or enable the interface. This is typically related to me disabling the interface when I want to route all traffic through the alternative connection. Like when the kids download a bit more than Comcast wants to allow without additional fees. I know I can buy unlimited bandwidth but the check I write to Comcast is big enough now and besides, I have another connection anyway.
The quick solution here is to restart the interface from the command line. To do this sign in to your edge router using SSH. Then check the status of the interface and restart it using:
“show interface <interface name>”
“disconnect interface <interface name>”
“connect interface <interface name>”
“show interface <interface name>”
If you return to the Web UI you should also see now that your interface is Connected.
Well, hope that helps if you run across a similar situation with your edge router.
