Hi, about 2 month ago my upload speed started being low (from 315mbps to 30 - 100mbps). The modem is sending out 300/300mbps, but the router sends out a low upload speed.

I have tried to factory reset it, but it didn't help. Also tried downgrading from the latest version 1.0.8 190411 to 1.0.7 180425. It is really odd, any ideas? And what info do you need to help?
