Hi everyone,
I’m running a Flint 3 on firmware 4.8.4.
I can successfully enable BBR via SSH (switching from cubic and setting fq as the default qdisc), and the router works fine from a networking perspective.
However, once BBR is enabled:
-
The GL.iNet Web UI becomes inaccessible / unresponsive
-
Routing, internet, and SSH still work normally
As soon as I revert back to:
- net.ipv4.tcp_congestion_control = cubic
…the Web UI immediately comes back without any other changes.
This is fully reproducible on my setup.
Has anyone else seen this on Flint 3 or 4.8.4?
Is the UI tied to assumptions around cubic, or is there a known incompatibility with BBR + fq on this firmware?
Thank you!
