Slower USB tether speed from router

Routers
1

I have a Flint 3 (GL-BE9300) and have it USB tethered to my android phone. My PC is connected via ethernet to the router and my speed test is about 267 Mbps download. However if I unplug the USB cable from my router and plug it directly into my PC my download speeds go up to 660 Mbps. Is this a fundamental limit of the router’s USB hardware? USB 3.0 should be able to handle speeds much higher than that.

Is there something wrong with my USB tether configuration? I notice a 65 Mbps bump if I disable hardware acceleration but that’s still no where near the maximum speed of my phone’s speed.

P.S. It’s not a ethernet cable limit. Setting router to repeater for phone’s hotpot then ethernet to PC results in a 839 Mbps download rate.

Hi

Basically, this is a hardware limitation.

USB tethering is a single-threaded task, constrained by the IPC ≈ CPU clock speed.
The rate you're achieving should be close to the upper limit.
