[SOLVED] Can't connect smart devices

I replaced my old router with openwrt router(x86), but used old router as AP. In old router I changed mode from router to AP. Didn't change SSID nor password, so I was able to use old connected devices(laptops, phones) without any issues. But smart devices like WIFI sockets cant connect to the network. I tried to reset them and reconnect but still can't connect. Can any one guess where can be a problem?

Without additional information about your setup, a guess is all it could be.

Typo in the SSID?

Typo in the password?

Unsupported frequency? E.g. 5Ghz instead of 2.4Ghz?

Unsupported encryption protocol?

Wrong phase of the moon?

What's the brand/model of the AP?

Let’s see the configuration for both devices:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:

cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Or even channel.

WPA3 is usually a no go here.

No, same SSID, same password (devices like phones, laptops working without setting anything)
Same settings of frequencies - 2.4GHz & 5GHz dualband, same encryption type.

What is the make/model of the the "smart" devices in question, and what method is used for their initial configuration?

The reason I ask is that there are plenty of so-called "smart" devices out there which are possibly the stupidest things I've ever seen. They require an app on your phone, or an existing Internet connection, or something equally brain-dead, for their initial setup. And, in many cases, for their ongoing use.

You might find that there's nothing wrong with your OpenWRT configuration (and I don't think there is, from perusing your config exports), but there might be everything wrong with the "smart" gizmos you're trying to use.

Ohhh...

Your wireless network is disabled. That'll be why.

Enable your wireless network, then try again.

Sorry!

Hi

maybe this has nothing with WIFI but ...

you see? eth1 is in br-lan and in same time it is WAN6
maybe will interfere with firewall or .. who knows

That definitely ain't gonna help. Good spot. I missed that one. Yeah, wan6 should be on eth2 just like wan is.

But the first thing the OP needs to do is change disabled to 0 or remove the disabled lines entirely.

I have installed wifi card inside openwrt, but I am not using it. I use separte AP.
Smart device - I mean WIFI sockets Modemix MOD044, this is some kind of TUYA WIFI socket.
To pair it I need to reset it using button and then in app I need to enter SSID and password.

Fix the Ethernet issue as suggested by @NPeca75. If that doesn’t fix the issue, let’s see the config on your ap.

Ah. Gotcha. That explains why OpenWRT's AP is turned off. Understood.

As indicated by @psherman, the other AP's own configuration may need to be checked if correcting the Ethernet configuration doesn't fix the problem.

Ok sorry for this topic, it turned out that it was my fault...
I was convinced that my smart sockets are using WIFI, but actually they use ZIGBEE... ;<
The problem lied in homeassitant addon, where server zigbee had wrong address (it had old address assigned by old router, not by OpenWRT)

I changed wan6 to eth2, thanks for your help!

Congratulations on getting to the bottom of the problem.

(I've never used Zigbee so if you have any further problems then I'm out of ideas...)
