p.s: while writing this, I remembered, that I for some reason, could only connect to the 2.4GHz network, before I configured the AP. After configuring, both 2.5 and 5GHz networks had the same SSID and Password. 
Could it be, that through this, the connection does not work?

 1. iPhone is not capable of telling the 2.4GHz and 5GHz if they are on the same SSID. You might wanna check the signal level. And if the signal is too bad or too much interference, the iPhone will not connect either.

2. Suggest you use different SSIDs.

3. Move closer and check if the iPhone can work with the WIFI.

p.p.s: I also noticed, that no matter what AP I use, the range is really really bad (every Produkt form Aliexpress has better range). For a divice, wich discribes itself as long range, it sould be possible to connect to it, if you are 10m away. Even if there is a wall between it!

Only happens to Apple products. That's why I turned away from iPhone after 13 years of being an Apple fan.

Not a single problem with the Android flagship models in my case/experience when the same model, same place, and same distance but the iPhone performs worse than Android. Not to mention the office got tons of WIFI signals due to the test purposes. iPhone would show up the signal bar as okay but not able to connect or way to bad in performance and frequent cutout. 

Maybe cheaper Android can do the same as the flagship one.

About your configuration, you might wanna share the details if it persists.

Esp your distance when connecting, errors, and symptoms.

OK, i now tried to connect, with only the 2.4Ghz active, but it still doesnt work. SSID shows up in wifi connections, but it cant establish a connection. All while i was standing directly in fri t of it

Hi Chris,

does the iPhone get an IP ?

Thank you,

No, I can not connect at all. It is just spinning. But only after i configured it.

Hi @Chris-Cross 

Thanks for posting in our business forum.

Do you connect the EAP properly? Spinning on the iPhone means:

1. You don't have an IP address.

2. Signal is too weak to connect.

Well, I was standing directly in front of it. And it does connect, to the Default 2.4GHz network, before I configure it. I can't explain, why it doesn't work.

I think you might get phone support and check the details one by one. Somewhere in the steps, you might be wrong.

If it is a hardware issue, from my view, I don't think so, you can finish the troubleshooting and RMA with the support.
