2.2.2.2 Internet authentication system can't be opened.

There is something wrong with the network or the website itself is being maintained.

Wifi that requires login authentication only shows that it is connected to WLAN. If you want to surf the Internet through WLAN, you must go through login authentication (although authentication and surfing the Internet are free in many cases, you can't omit the authentication process, such as airport wifi and KFC wifi). Wifi access control can be divided into the following categories: 1. Set the password for wifi access. People who know the password can directly connect to wifi and access the Internet (this is the most common way). 2. Turn on wifi, and any device can access it without a password, but Internet access is restricted by mac address filtering or static address binding. 3. Turn on wifi, no password is required, and any device can access it. However, access to the Internet is restricted through secondary login authentication.

First, check whether the wireless router is working properly. You can use other mobile phones or digital products to connect wifi signals. Generally speaking, this router can work normally if it can connect to the Internet normally. 2. The mobile phone is turned on and the network is turned off. Check whether the phone has turned on the option to turn off the network when sleeping. The phone will be disconnected after a period of time or may not receive background chat software. The possible reason is that the function of closing the network when sleeping is turned on by mistake. 3. If you use the router for a long time, the router may be in suspended animation. Just restart the wireless router. 4. The authentication type is not appropriate. When trying to change the authentication type of the router, it is best to choose the secure "wpa2-psk" type mode, and the following encryption algorithm is best to choose "aes". 5. The mobile phone or router network settings are abnormal. Consider restoring router factory settings and mobile phone network settings.
