Wifi is unstable and not working on 2,4GHz

[aloha_ian]

Hello,
I am a vodafone user with 'Red Internet & Phone Cable 250 with Vodafone station'.

I recently found something weird for the router.
Issue1. Wifi connection is unstable. it is disconnected very often and cannot connect it again for a while.
Issue2. Devices which support only wifi 2,4GHz cannot connect to the router.

Could you please follow up my issues?
Here is what I figured out.
I think that the router has some problems.

The router I am using is 'vodafone station' which supports 2,4GHz & 5GHz. (is the router's specifiation right?)
But it looks like WiFi is not working on 2,4GHz, only working on 5GHz.
To find causes, I prepared two AP more 1)enabled mobile hotspot as 2,4GHz and 2)another AP which supports 2,4GHz & 5GHz.

1) checked with the router's wifi radar via 192.168.0.1
The router cannot scan any devices on 2,4GHz envrionment at all.
But it can scan AP devices on 5GHz envrionment properly.

2) checked with any wifi analyzer apps installed on my smartphone
They can scan my additional APs on 2,4GHz properly.
But the router cannot scan them on 2,4GHz envoironment.

Hi aloha_ian,

have you ever reset the cable router to factory defaults?

Best regards, Martin

I resolved it by myself.

The precondition was that I made 'band steering' disabled.

After that, I just had a test for 2.4Ghz connection immediately.

2.4Ghz AP was appeared but not working.

The problem was that I didnt restart it after changing configuration.

Ater restarting the router with changed configuration, it works now.

It was my mistake.

Martin59, Thanks for considering this issue together.
