TRB501 slower 5G speed after Device firmware update

Networking Solutions Issue
1

After updating firmware to TRB501_R_00.07.21.2 I get 1/4 (150 Mbps) of the speeds I initially had (500-600 Mbps). To try it out I downgraded to version TRB501_R_00.07.20.3 and my speeds/latency are restored. The downgrade in speed Im thinking must of happened with earlier updates also (maybe 07.21+).

I’ve tried speedtests in various hours throughout the day and it always seems that the speed is capped to 150.

On the bright side, the connection seems stable now - no disconnects at all

This has NOT been resolved with TRB501_R_00.07.24 sadly.

Its kinda sad that after almost half a year and many many CVE patches, this major bug is still present. It shines a really bad light at the company imo, its not a tiny bug its a major bug requiring an instant hotfix, not 5 months of ignoring
