Hello @ayansaari 

  I believe the b/g/n is coming up but the way the WLC is showing is confusing you. They might be among the Dual-Band Radios. You can check this by creating a new SSID for testing purpose and advertise it only in 2.4Ghz frequency. If you see the SSID around, means the 2.4 Ghz radios is working.

What you can also do in order to show per b/g/n radios is disable dual radios.

config 802.11-abgn {enable | disable} ap-name

Refer to this guide

Hi @Flavio Miranda 

But I check the video on youtube about wlc configuration and they're showing their dual network is UP.
1- can I disable dual band radio ?
2- can I enable 802.11a/n/ac Radios & 802.11b/g/n Radios ?
3- Now problem is that 802.11b/g/n Radios is not UP | Down so due to this we're unable to get printer on mobile and our Huwaie Solar Invertor is not connecting to the WiFi.

Please help me in this issue.

Your 2.4 Ghz radios is not showing down. As you can see, there are zero radios bgn down.  Did you create an SSID for test and advertized only in 2.4 GHZ?

PS: I will not contact you, this is not the idea of this forum.

[ayansaari]

Yes I did it but still unable to advertise pritner and solar invertor not connecting to the wifi. can I disable dual-band radios ?

I am in trouble

[Flavio Miranda]

Yes, I would try to disable the dual-band radios but it should not be a problem. Dual band means 2.4 and 5.0 Ghz, meaning, your devices should connect.
