Yeah but what am I looking for, I have no idea? All I know is that during load shedding using the same LTE router wifi with my iPad and Android phone the iPad is very very slow and the phone is fine. It makes no sense. It's not physically connected to anything.
It will give you the stats like channel, congestion on the channel, signal strength, latency to router, latency to internet etc.
It’s Apple so you know green means good and red means bad or it will outright say it.
Secure DNS is the other issue, also check Safari and your Wi-Fi connection for “Limit IP Address Tracking” and turn it off.
By default now I think if you’re not using secure DNS, it will use Apple’s for Apple’s services which can make things laggy.
Also if you have a Type-C iPad, you can just plug in an Ethernet adapter and test using a cable.
