Archer AX12 purchased maybe a year ago, never any issues until this week were my WAN connection drops every 10 minute or so, only to come back a few minute later. Router is connected to some kind of hub in the house, and only the devices connected to the router are affected. WAN light turns orange when disconnected.

I've tried to things in the troubleshooting section with no luck, and now I'm trying to revert the firmwave version to the previous one (because it worked) but when i try to do it manually i just get an update error. I've reset the router to factory settings but that didn't seem to change the firmware. 
I've used my regions website to get the offical previous firmwave here https://www.tp-link.com/nordic/support/download/archer-ax12/#Firmware

Location: Sweden
ISP: Bahnhof Fiber connection

How do i flash or overwrite the lastest firmware? 
Forum won't let me upload my log so I'll post it below.
