2.4 GHz channel slow at <1mbps download speed
I have just purchased my Archer Ax55 and have not been able to have the 2.4 ghz channel function at full speed. The signal strength is strong and I can connect to the network anywhere in the house but even right next to the router, the average dow load speed I see is 47.5 kbps. The 5ghz channel functions properly. From my IP I should be at 250mbps and I see roughly 280 from ethernet and anywhere from 80-240mbps on the 5ghz channel.
I have reset the router, I have made sure eco mode and QoS are off. I have checked for updates and I show the router is up to date. Aside from a factory reset is there anything else that can be done?
Also I have only had the router for about 2 weeks and the 2.4ghz has never functioned.
