Wireless Joint

Following numerous guides I set up TTL mangling on my Beryl.

My setup is

M1 (Ethernet)--> (WAN) GLiNet Beryl (LAN) --> (WAN2) USG Pro 4

This is purely for my backup WAN on the USG

All 3 devices are set with DGHCP enabled because it was easier than trying to get bridging and ip passthrough ...

I'm stuck on this part of the guide for creating the bridge

If you are Ethernet tethering:

Delete the WAN and WAN6 interfaces
Select the Devices tab
Under Devices -> br-lan click 'Configure...'
Under the General device options tab
Add 'eth1' to Bridge ports
Click 'Save' and then 'Save & Apply ...

This is exactly the setup that I'm going to eventually have. Still working on setting it all up. Since you determined that it wasn't hotspot detection as the reason you were being throttled, how can you tell whether or not your setup is successfully circumventing hotspot detection?
