Wi-Fi Disabling

Installing and Using OpenWrt
1

I have a small local Wi-Fi network based on a router with OpenWrt version 24.10.0, which is configured as a Wi-Fi AP and as a Wi-Fi client of another network.
My OpenWrt works in the client mode of another Wi-Fi network and at the same time as an access point for my computers.

That is, my OpenWrt is both a Wi-Fi client and a Wi-Fi AP

The problem is that if the AP for my Wi-Fi client is turned off, then my Wi-Fi AP is also turned off.
Having lost connection to the Internet, my OpenWrt turns off the Wi-Fi transmitter.
As a result, computers in my Wi-Fi network are left without communication with each other.

How to solve this problem?

This is a problem when you have a single radio - the sta (client) mode connection must be established first because it determines the channel that will be used for the AP mode operation (they must be the same).

Travelmate is designed to deal with this by gracefully failing when the upstream ssid is not available.

Or, alternatively if you have a dual radio device, use one radio/band to connect to the upstream and the other as an ap.

Thanks for the answer.

I have TP-Link TL-WR842N
This router has two antennas.

The router is based on the Atheros AR9341-dl3a chip, which has two RF channels.

(page 97)

Perhaps I need to edit the /etc/config/wireless file in OpenWrt to use both channels of this chip?

you claim to have a TL-WR842N v5, it doesn't use this chip.

Thank you.
You are right. I found on the Internet that my router is based on AR9341-dl3a
I opened my router and found MT7628-NN chip.

Is it incompatible with my task?

the singe radio scenario described earlier by @psherman applies here.

Ok. (((((
it's sad

Please tell me how to choose a router compatible with OpenWrt and having two radio channels

8

pick one that will have at least one radio in the 2.4 and the 5GHz column.

in addition to the radios, choose one with at least 16MB flash, and 128MB RAM.
