No wireless associated and 5g radio off problem Xiaomi 4a gigabit edition router

In LuCI, navigate to Network > Wireless

Click Edit for the 5 Ghz device

Click the Advanced Settings tab

Country Code is at the top

I would not allow the router to automatically select the channel.

I have seen some select a DFS channel, which is reserved for radar.

Depending on your location, select in the range 36 to 48, or 149 to 161.

If you are still having issues with wireless after completing your configuration, SSH in to the router and run the following command...

cat /etc/config/wireless

Redact the passwords in the "option key" sections.

Post the output in pre-formatted text using the icon highlighted in red...

You may need to add it to your mobile.

You can change to PPPoE in Network > Interfaces > WAN > Edit > Protocol

yes done it works now can you help me on why the 5ghz ssid wifi name isnt showing on my mobile wifi

fwiw, does your mobile device support 5 GHz?

What is the make/model ?

yup it sure does it used to show when it was on original xiaomi firmware

model

Samsung A52 5G 2021

Singapore is not listed in the Wikipedia article I posted above on WiFi channels.

However, 128 is a DFS (radar) channel in most countries.

Pick one that isn't.

Yes done i set the 5ghz channel to 161 and it shows now

Can you tell me how to use https on luci panel?

Https://192.168.1.1

Set option redirect_https '1' in /etc/config/uhttpd

Doesnt work as expected

It's a self-signed certificate, so you'll get the warning.

any way to remove it?

You would need a certificate signed by a CA.

so how can i get it for free btw i saw some pre installed certificates from httpd

You might look into uacme, which works with Let's Encrypt...

i am newbie to all this if you can give me stepwise /.....

I have no experience with uacme and Let's Encrypt.

You might start a thread on it.
