The load is small: a laptop via WiFi and a computer via ETHERNET, sometimes phones are connected. I turned off the WMM setting, as advised on one of the forums - it did not help. Maybe other versions of the router work better. I have V11, since 2022 they have not released a firmware ate. It is not interesting to download third-party firmware at your own peril and risk. The router really upset, because. Before him, the Rostelecom router worked flawlessly until I had to return it to them.
