Hello, I am having performance problems with the Archer AX73 wifi router, which is not reaching the real value of the internet contracted with the provider on the 5ghz WiFi network. I performed the test with only 1 device connected to the router and being 2 meters away from the router. Using the network cable, I had a satisfactory result, which presented an internet speed of 510mb, and I have contracted with the 500mb provider for optical fiber. Everything is ok, but when performing the test using the 5ghz network, the result is disappointing, with a value of 260mb to 310mb. I've performed the test on several different devices, and from different manufacturers (cell phones and Xbox one x), and the result is always the same, being below the contracted plan. I've already tried disabling some options on the wi-fi, such as leaving only in AC mode, taking out simultaneous AX (since I don't have devices in this new standard), changing automatic to fixed channels, changing the transmission power, or even disabling the additional options of wi-fi (network congestion, among others) and the problem always remains. Then I came to the conclusion that the problem may be with the router, requiring some firmware update to fix the problem. I also inform that the router disconnects from the WAN at random, I use the PPPoE protocol, and I always notice a connection failure for about 2 to 5 minutes, usually the case occurs once a week.
