I recently upgraded my home network from a miss-match of TP-Link and ASUS gear to Ubiquiti.
I’m using one of the new Unifi Express routers with an AC-Mesh access point using a GBe uplink.
Everything is working well but the Starlink app on my phone could no longer connect to my Starlink system.
I found that this is easily resolved by adding a static route to the starlink network on the WAN port.
With this in place the Starlink app works fine on my phone and I was able to apply pending software updates.
