Why is the speed of the wireless network on the iPhone so slow?

The reason why the iPhone is connecting to the wireless network very slowly may be due to the location of the router. It may also be due to the router itself. It may also be due to signal interference from surrounding devices. Or the speed of the router is limited. Or it may be due to the problem of the phone's protective case.

The problem is the location of the router. The router is far away from the mobile phone or there is a wall between them.

The problem is with the router itself. The router may be damaged or the router broadband account may have stopped network service.

Signal interference from surrounding devices. Most routers use 2.4G frequency, and when there are many devices, they will interfere with each other.

The router speed is limited. This is mostly because the speed of the router is limited manually.

The problem with the mobile phone protective case is that the metal protective case or metal frame case will affect the Wifi signal.
