Why does the Internet disappear over wi-fi Zyxel Keenetic?

Question

WiFi

Hello.
There is a Zyxel Keenetic router with two antennas which.
Several devices are connected to it via Wi-Fi
Recently, a problem has appeared, the Internet falls off very often, and on all devices, but not simultaneously, but separately. For example, there is an Internet on a computer, but not on an iPad, or vice versa. The combinations are all different.
The wifi itself works.
In the router settings, in the "List of connected Wi-Fi devices" section, a message "Obtaining an IP address" periodically appears near each device.
Here is the screen - take.ms/S9McJ
And apparently at this moment the Internet disappears on this device.
Tell me how to fix?

Answer 1

by default in kinetics, the lysis time is 10 minutes. Put more time, there will be no such problems. This is done through the CLI, you need to telnet to the router and give two commands

ip dhcp pool _WEBADMIN lease 7200
system config-save

The example sets 7200 seconds (2 hours), you can do more.

Answer 2

Maybe someone is trying to break or the signal is lost from some kind of microwave
manually set the channel

Answer 3

Because this is a buggy router, I still couldn’t decide, I had to install a computer instead of a router.
