no connection NodeMCU with internet

[unknownBob]

Hello guys,
i am using the switch example from kakopappa to connect the nodeMCU witch the internet. The only change I did, is adding MySSID WifiPassword and MyApiKey. But there is no connection. Do you guys have any idea? The adding variable I checked allready 1000 times. What else can be the mistake?

output:

Connecting to Wifi: Wodafone-t@..

Check whether you are you connecting to 5G WiFI.. MCU does not support 5G also, try changing the WiFi channels on router you can also start a hotspot from your mobile and try to connect to it confirm

With a hotspot from my mobile phone it is working!!!!!! NICE

Now I try it witch wifi
I used seperate SSID for 2,4 and 5G, but it dont work with 2,4.
I also changed the wifi channel and the Wi-Fi Protected Access without success.
Any other ideas?

I remember I had the same problem long time ago. I go remember changing the WiFi channels and trying again When you scan for WiFi can you see it? https://arduino-esp8266.readthedocs.io/en/latest/esp8266wifi/scan-examples.html

Thanks alot for the incredible fast answer!!

I tried it with changeing the channel again. With the scan example I can see my wifi:
6: Test, Ch:2 (-45dBm)

But a wifi connection is not possilbe.

I am having the same issue, No Wifi connection. I've connected with Feauxmosp with the same Node. I as well have checked the SSID and Password 1000xs.
