Review on Wi-Fi router TP-LINK Archer AX20, black by Mateusz Praga ᠌

1) I implemented the 5 GHz band in a truncated form, only channels of the main sub-band are available - 36, 40, 44, 48 and that's it ! The times when no one was on 5 GHz, now all operator routers work in this band (Beeline, Rostelecom, Dom. Ru, etc. ), so the air in this band is already well packed, in an apartment building. Accordingly, this router cannot work on channels from 50 to 64, and even more so from 100 to 140! With all the consequences. 2) Wi-Fi 5 GHz freezes periodically, there are connection stash on devices, but in fact there is no data transfer. Restarting the router helps. During the day I saw such a disgrace 3-4 times. Also, there are problems when at least one device (smartphone) refused to connect to the WiFi network in both bands. Restarting the router helped. 3) The general capabilities of the mobile application are very modest and do not allow you to fully manage the router. There are no statistics at all, traffic filtering to a specific device, parental control is also implemented for show, in fact it is useless. In the mobile application, in the information about connected clients there is no information about the connection speed (I have not seen such a defect on any other router, other manufacturers) Naturally, all of the above was observed on the latest firmware, after ating the device.
