Can't get IP from single SSID on 2.4Ghz and 5Ghz Wi-Fi network

Installing and Using OpenWrt

I can't get a single SSID on 2.4Ghz and 5Ghz Wi-Fi network to give me an IP address.

If i disable either one of the Wi-Fi interfaces, I am able to get an IP address.

Any idea on what I could be doing wrong?

I think it should be the same as your 2.4G and 5G SSID, please modify the name of the different SSID.

Both Wi-Fi interfaces have the same SSID.

network>>wifi
2.4G SSID:LEDE_2.4G
5G SSID:LEDE_5G

It appears that adding option type 'bridge' to the testnet network interface in /etc/config/network made it work.

Could anyone explain why this made the difference?

@jow I got the hint from a post you made on the OpenWrt forum. Maybe you could shed some light?

I want the 2.4Ghz and 5Ghz interfaces to have the same SSID, not different SSIDs.
