RT-N66U Disable Wi-Fi

[wegl]

Hello
In Wireless - Professional i disable 2.4 Ghz but i can't disable 5 Ghz.
In Band list box only 5GHz. And when i apply "Enable radio NO" Nothing happens.
Firmware 378.55 by Merlin

The query is a bit confusing.

You mentioned that you are able to disable 2.4 Ghz but cannot disable/see 5 Ghz.

Then again you mention that 5 GHZ is only available in band list which means 2.4 ghz is not availalble.

Even I am on 378.55 from Merlin on RTN66U and have no issues with both bands.

For clarity:
1. Can you see in the drop down list both 2.4 & 5 Ghz bands?
2. What bands are available in your band drop down list?
3. Router model ?
4. Factory reset after flashing firmware ?

 

[wegl]

1) only 5 GHz
2) available 5Ghz in Wireless General and in Professional
3) ASUS RT-N66U
4) yes factory reset and after flashing original asus firmware showing only 5GHz

When apply Enable on Band 5Ghz enable 2.4 band. I can't disable 5Ghz band.

Click on the 5ghz or 2.4 ghz, (whichever you see) you should see the other band. It is a drop down.

2) available 5Ghz in Wireless General and in Professional

When apply Enable on Band 5Ghz enable 2.4 band. I can't disable 5Ghz band.

Can you check the System Log for the below

Click on the 5ghz or 2.4 ghz, (whichever you see) you should see the other band. It is a drop down.

In BAND list only 5Ghz

This sounds like an issue that was fixed a long time ago relating to some bad nvram settings. You said you did a factory reset after loading the code. Just to verify, that after the factory reset you reconfigured by hand and did not load a saved configuration (which would put the problem back).

 

[spalife]

It looks like both your bands 2.4 & 5 are getting recognized and are getting started.

Interesting from your logs that when you turn off 5 GHz, it turns off and then turns back again.
As mentiond in your \\Disable in band list 5Ghz comment.

The UI is messed up somehow and showing you only 1 band,
Maybe a bad flash/upgrade procedure.

Troubleshoot:
1. unmount and remove any usb devices from your router
2. Also disconnect any other camera's / hdd's / ip devices from the router
3. check if 5 ghz and 2.4 ghz led lights are ON your router
4. check if the 5 ghz and 2.4 ghz with ASUS default SSID or SSID set by you, are being broadcast, you can check with your desktop / phone / ipad etc.,
5. Just make sure the router is powered on and has Net connection from your ISP. (you can check the led's for guidance)

If you can see the 2.4 ghz led's turning on and see 2.4 ghz being broadcast from your router but not showing up on the GUI, then it was a firmware upgrade which went bad, reset to factory defaults and do the upgrade process again.

To verify John's theory, check the content of these two values, over SSH:

nvram get wl0_nband
nvram get wl1_nband

If either of them returns -1, then you have the corrupted value caused by a bug that was fixed a year ago. Try setting them as follow:

nvram set wl0_nband=2
nvram set wl1_nband=1
nvram commit
service restart_wireless
