2. The wireless network password can be entered into the router to view, or ask the insider. Only when you know the wireless network key can you connect to the Internet.

3. The reason why the wireless network sets a password is to prevent someone from connecting to the network at will, which will cause the network speed to slow down.

I'm sweating: People's wireless networks have a password, and you have to ask the owner of the wireless signal to tell you the password before you can access it.

In there is a factory reset, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set it at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, not that the router is broken).

4.If it is caused by a system problem, it is recommended to restore the system or reinstall it.
