Hello everyone! My BR1 Pro 5G router (firmware version 8.5.3) is experiencing a tricky issue and I need some help.
For the past week, the SpeedFusion tunnel between my router and FusionHub has been randomly disconnecting—usually every 2-3 hours. When it disconnects, the router’s WAN (cellular) signal is still strong (around -75dBm), and a quick reboot of the router temporarily restores the tunnel connection… but it disconnects again after a while.
I’ve already tried:
Rechecking the SpeedFusion configuration (PSK and IP settings are consistent with the FusionHub configuration)
Updated to the latest 8.5.3 firmware (hopefully it fixes known stability issues)
Checking for loose cellular antenna connections
Has anyone encountered a similar issue with random SpeedFusion disconnections in version 8.5.3? Which specific logs should I check (e.g., InControl 2 logs or logs in the router’s local UI) to narrow down the problem? Are there any configuration tweaks that can help stabilize the tunnel connection?
Thank you so much for your insights!
