how to know if that data are correct or not ?
the problem is, Next to the router, the signal is good, the farther it is, it weakens, up to three to four meters, I lose it.
That depends on the router you use, and how it is set up, for example, is Channel width -> set to Auto?
and put the the password, it gives error ( the password is wrong or unable to Join the network )
The Wi-Fi network name is the name your network, and has a password, the iPhone 6S must use the same password.
A question:
Has hotspot been turned on by accident? If so, the iPhone 6 uses other existing devices as a hotspot, piggybacking to get a connection. And that may explain why the Wi-Fi is weak, if it is too far from the route and/or other devices.
