Wi-Fi name is not displayed?

HI, this is a Vodafone router. I can connect well with all cell phones, only not with the one Huawei cell phone. All WLANs that are available in the block appear, but not our WLAN. Request for help (airplane mode is off, I restarted both the cell phone and the router several times)

You can set in the router that no new devices are displayed. That is probably switched on.

Well, I haven't changed anything manually yet

Maybe reset the phone?

OK, then something else

Yes, only ours

First try to connect yourself manually. So add WLAN networks and then enter the data exactly as it appears on the back of the router label, unless you have already changed this data.

Go to Configuration> Saved Networks. Find your SSID and delete this entry. Then you re-enter the data.

I try, thanks
