Dear Lenovo users, hello!

Generally, laptops are pressed fn plus f, and there is a wireless pattern on the keyboard. There are computers such as socks, such as IBM's wireless dismantling switch is a real switch button on both sides of the computer, your computer is in**, you can also ask customer service, read the manual (sometimes it is not caused by the network card not being opened, please see below).
1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.
2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. 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).
If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.
3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, Oakland is caused by the network card driver is not or is not suitable, the network cable interface or network cable is not a problem, etc.
4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.
