How can I downgrade to the previous version when this firmware says it is unable to downgrade? I tried the most recent version Archer AX10(US)_V1.2_201116 as well but it is even worse. My internet speed and ping are much slower and unstable when I used these two versions but it works fine on Archer AX10(US)_V1.20_200706. Is there any way to reset the version to the factory firmware or downgrade to Archer AX10(US)_V1.20_200706? The internet speed is very unstable. 200 Mbps is sometime tested 150mbps, sometimes 30 mbps and sometime the normal spees.
