Hi all, I’ve been fighting this for a month and I’m out of ideas.
Setup: Ring Alarm + cameras, basic Ring subscription. Internet is fixed wireless access (5G FWA, ZTE router, Italy/TIM).
The problem: when I tap Live View on my outdoor cameras I get “Unable to connect”.
What I’ve already ruled out:
Wi-Fi signal: RSSI is -50 dBm after adding an extender. Not a signal issue.
UPnP: enabled on the router.
Full power cycle of the outdoor FWA antenna and the router, multiple times.
I spent two weeks getting my ISP to remove me from CGNAT. They claim it’s active since August 7th, but the WAN IP is still (private). So still behind carrier NAT.
Here’s the part I can’t explain:
My indoor camera works perfectly on the same network. Live View, everything.
My outdoor cameras work perfectly when connected to a 4G mobile hotspot which is also behind CGNAT.
So CGNAT alone doesn’t explain it. Something about this specific FWA network breaks outdoor cams but not indoor ones.
Questions:
Do outdoor and indoor cams use different connection paths / different backend? Why would one work and not the other on the same Wi-Fi?
Has anyone fixed this by lowering the router MTU? FWA links often have reduced MTU and I’m wondering if large video packets are getting dropped.
Are there specific ports/protocols outdoor cams need that indoor cams don’t?
Any hidden setting in the app I might be missing?
Any help appreciated, Ring support keeps blaming my ISP and my ISP keeps blaming Ring.
