How to fix a large number of Tx errors?

Question

WiFi

Good afternoon gentlemen, please tell me to solve the problem with Tx errors. Recently I noticed that the Internet began to freeze, in online games there are constant packet losses. The apartment has one stationary computer connected by cable, and a laptop with three smartphones connected via Wi-Fi. Out of curiosity, I got into the admin panel of the router (D-Link DIR-615A) and saw this in the statistics window:

I googled it, the only advice I found was to reduce the transmitter power, but this did not help.

Please let me know what could be the cause and solution. Thanks in advance!

Answer 1

Reasons:
Microwave and many other devices. At the dawn of the advent of WiFi, there were cases - we connect a laptop and all those already connected lose their connection. In Wi-Fi, the service "overhead" is very high - the same packet can be sent several times so that the parity converges.
Methods:
1) Channel selection. In my opinion, the more the farther away from 2400 MHz, thereby reducing the impact of household appliances.
2) Disable broadcasting. It will only respond to devices that "know" it.
3) "Dancing with a tambourine" - play with all possible parameters. For example, hardcode the 802.11g transmission standard and see the number of errors.
Most important
Buy a 5000 MHz router, old devices may not connect)))
