[SOLVED]I can't put two guest wifi on the same interface

Hi.
I'm trying to put two guest networks on the same interface, the first network works (wlan0-2), but the second one (wlan0-3) keeps looking for ip and doesn't even connect

My configuration is this

/etc/config/network

config interface 'testea'                                                                                                              
        option proto 'static'                                                                                                          
        option ipaddr '10.10.9.1'

Please also give the router model (and target) and your complete wifi config file. I can't tell if I will be able to help you, but others users will need these infos to answer you. Some devices may have specific issues with wifi.

Also an iw list , there might be a limitation on the driver.

Could you try to delete one of the other interfaces and verify that the 2 new ones both work?
I am under the impression that you have hit a limit of 4 interfaces.

badulesia · May 30, 2022, 3:30pm

That should not solve your issue, but put the same country in both interfaces. You seem to live somewhere between Brazil and Venezuela ?
I have made test with R6220 (mt7621 with latest snapshot). On the radio1 (5Ghz), I have set 2 AP, one with key password, one without, and I ran in the issue than you: device can't get an IP.

viniribeirossa · May 30, 2022, 3:33pm

I live in Brazil, is it a country problem, I'm going through BR

viniribeirossa · May 30, 2022, 3:44pm

I put the two networks (wlan0-2 and wlan0-3) 2 connects and 3 is trying to find IP

mk24 · May 30, 2022, 3:55pm

The problem here is that testea is not a bridge. A non-bridge interface can only have one physical device. For dual-band wifi or wifi plus Ethernet, make a bridge br-testea along the same principle as the default br-lan.

viniribeirossa · May 30, 2022, 4:21pm

I made the bridge and grouped the networks, but now none of them can get ip so is looking for ip

config interface 'testA'                                                                                                               
    ...                                                                                          
        option type 'bridge'

That is wrong. option type bridge in an interface section is the deprecated old syntax, and can't be combined with the new standard of separately declared bridges.

Also don't use uppercase in network names. By convention the bridge has the same name as the interface except for adding br- at the front. I don't know if not following that convention works or not.
