Dear Lenovo users, hello!

Dear Lenovo users, hello!

It is recommended that you restore the BIOS factory settings, the recovery method: go to BIOS, then select Restart, and then select Load Setup Defaults to restore the default settings;

In addition, please turn on the physical switch of the wireless network, and then press the function key FN+F5 or F9 to turn on the wireless network function, if the function key is invalid, it may be that you have uninstalled the relevant driver, it is recommended that you use the power management software driver and hotkey driver on the official website of Lenovo;

Think Forum:

There are two possibilities, the network cable is broken, or the router is broken, and it has nothing to do with the computer.

Lost a password? Is your router agent set up?

That kind of network requires authentication.

Are you still using the legendary XP SP2? SP2 does not support the current mainstream WPA2 encryption, so you have to change the encryption method of the route to WPA or WEP

Here's how to solve the problem if your Lenovo computer suddenly can't connect to the wireless:

1. If the laptop cannot connect to wifi, you should first enter the device manager to see whether the network adapter, the built-in wireless network card driver of the laptop is normal, and whether the wireless network is disabled. If the NIC driver is not installed properly, the wireless NIC will not be found here or there will be a yellow exclamation mark on it.

2. If the wireless network card driver is normal, you can enter the network adapter and look at the wireless network properties and other information. To do this, right-click on the "Network Icon" in the lower right corner, then click "Open Network and Sharing Center", and then click to "Change Adapter Settings" on the left. The main thing is to see the status of the wireless network and other information.

If you have a network cable plugged into your computer and you are not using a wireless network by default, you can unplug the network cable plugged into your computer, and if wireless is turned on, it will automatically switch to the wireless option.

3. For most of the people who encounter this network problem, mainly laptop users, they are using a wireless network. When connecting to other wireless networks is normal, but a wireless network cannot be connected normally, this problem is mainly caused by the router's wifi wireless password has been changed.

4. You can forget this wireless network first, and then reconnect, enter a new wifi password to successfully connect, and you can also directly modify the wifi password of the current connection, or connect the network cable to the laptop and the router, and then enter the router settings, modify the wireless network SSID name, and after completion, restart it.
