Hello @Karthick Palanisamy,

welcome to our o2 Community

You may have hidden the SSID of the Wi-Fi network so that it no longer appears. You can change this again in the router settings under “5 GHz und 2.4 GHz WLAN Einstellungen”.

Please let us know if this was already helpful or if you need further support.

Best regards

Giulia

Thanks for your information and  time .

I  have cross checked , it is disabled already( refer attached image ). 

Kindly guide any points to validate . Yesterday I have raised a compliant in O2 service . they just simply raise a ticket and went off not even verified any setting on my router . Really bad .

thanks  and regards

Karthick

Have you used the WiFi switch on the top of the router?

Yes friend . My WLAN  lamp is ON.

Have you checked the wifi channel? Some higher channel (i think > 11) could not be handelt by some devices. Try to switch off one SSID and take a other name for the 5GHz or 2.4 GHz WLAN.

At least you could press the rest on the backside for more than 45 seconds and tray again.

If not the i would like to think you have a defect of the router.

Hello.

Thanks for your great support.

Just spoke with Technical team from O2. they have confirmed as problem with hardware and they are going to replace this faulty router.

Thanks again,

Have a nice weekend 

Hello @K_P_ ,

welcome to our o2 Community 

That is unfortunate, that your router is defect. But good to read that you already organised to have an exchange router sent via our Technical team 

The defect router you can register to send it back to us via our Portal.
