The first two answers are not the donkey's lips, Huawei mobile phone was refused access to wireless, obviously, this is WiFi access, but also pull what mobile phone card... Just a little!
This situation needs to determine the WiFi environment, home or public WiFi, but regardless of that environment, the problem is on the access point
Home is easy to manage... Remember the PPPOE account password, reset the router directly, simple and rude...
Public WiFi is in trouble, it is estimated that it is on the blacklist, (such as the sta-blacklist of Huawei switch I use here)
Contact the network management... I can't do it myself
The reasons for mobile phone network denial are as follows:
1. Mobile phone reception problems, suddenly interrupted contact, try to restart the phone or open the airplane mode.
2. Check the network connection and reconnect it.
3. When browsing the website on the mobile phone, the virus accidentally causes the mobile phone system to make an error. You can use the mobile phone anti-virus software to kill the virus.
4. The carrier network is faulty.
5. Hardware problems of the phone.
