Dear, hello, I'm glad to answer for you: The reasons why Apple's home wifi can't be connected are as follows: 1. The failure of the wireless router itself This is a common fault that may exist in daily life, and the very simple solution is to try to plug and unplug the power interface of the wireless router and let the router restart, which can solve 90% of the problems caused by the wireless router.

If the hardware equipment of the wireless router is faulty, you can choose to send it for repair or replace it with a new one. In addition, there may be a problem with the router configuration, which depends on whether the wireless router itself can connect to the Internet. 2. The router is connected to too many devices at the same time, and this kind of problem generally occurs in the office environment, or in some public places such as free wifi coffee and large shopping malls.

If you don't have the administrative privilege to change the router settings, you can only minimize connecting during peak network hours or connecting to the Internet early. In the event of an IP conflict, IP assignment should be performed on each connected device in the wireless router to prevent harm to each other. 3. The network signal of the wireless router will be weakened by the sound of the old and clear sound beyond the area covered by the data signal, simply put, the spacing, the general wireless router will be worse and worse if it exceeds ten meters.

Therefore, when connecting to WiFi, get as close to the source as possible to improve the WiFi data signal. On top of that, when you have a physical separation from an infinite router, such as a wall, the data signal will get worse and worse. 4. If there is a problem with the wireless network card, the wifi data signal received on the mobile phone is maintained with the help of the wireless network card in the mobile phone.

Some mobile phone wireless network cards have long been eliminated or are seriously weakened, which may lead to poor acceptance of wifi data signal, and may cause wifi disconnection when a ** is entered, and this time can only be sent to the mobile phone repair center for repair.
