So my super-duper-awesome RB4011 started to have issues lately where my gigabit internet service would drop to kilobits. Super bizarre stuff. I tried a laundry list of things which I'll save for if anyone asks but I obviously rebooted it numerous times, turned things on and off and tried different interfaces for my ISP connection to the ONT.
The router ran fine for some time though and I don't recall changing anything just before the problem occurred.
I should say the one thing I did notice was a shitload of TX pauses on the ethernet interface going to the ONT (I didn't check others). Even when I turned flow control off, I still had heaps of these. Like, millions and they kept incrementing.
It was fixed by downgrading to the Long-Term version 6.46.8. Like, instantaneously fixed.
Anybody else had similar problems on similar hardware?
