No matter how sturdy and well-built the Lenovo Laptops are, they are not immune to the common problems that plague other manufacturers’ devices. Issues with Wi-fi connectivity is one such problem frequently experienced by Lenovo Users.
The majority of Lenovo products come with Broadcomm chips, which have been known to have serious bugs that cause Wi-Fi connectivity issues. The main contributors to this problem appear to be bugs in WLAN adapter drivers and misconfigured Power management settings on Windows.
Other factors are also contributing to this issue, which we will discuss in detail and offer solutions to help you connect to Wi-Fi.
Reasons for Lenovo Laptops Not Connecting to WiFi
- Wi-fi Switch on the Laptop is turned off
- Issues with the Router
- WLAN is disabled in BIOS
- Wireless adapter driver is disabled
- Incorrect password used for connecting to the Wi-fi
Fixes for Lenovo Laptops that won’t connect to WiFi
To begin, check to see if you have enabled Wi-Fi from the system tray. If you can’t turn on Wi-Fi or connect to a Wi-Fi network, restart your computer and see if it works now. Sometimes some minor glitches in Windows can also cause such connectivity issues that get fixed by the system restart.
Another possible cause of this Wi-Fi connectivity problem is not properly configuring the Wi-Fi Network’s authentication process. Check that you are attempting to connect to the right network and that you have entered the correct password.
Turn on the Wi-fi Switch
Lenovo laptops include a dedicated Physical switch that can be used to turn the device’s Wi-Fi on/off.
On most Lenovo Laptops, pressing Fn + F5 gives you access to the Wi-fi controls. For the Idea Models, pressing this key combination will open the Lenovo Wireless Device Settings window. Ensure that the Wireless Network card is On in this setting.
For the latest Thinkpad models, pressing the F8 gives you the option to enable or disable the Wireless Radio. Make sure to change its Status to On if you find it disabled.
Rebooting the Wi-Fi Router
The issue could very well be related to your Wireless Router. Therefore restarting the router is always the first thing to do for most connectivity issues.
For this, disconnect the Wireless Router from the power source. Wait for about 30 seconds and plug it back. Finally, check if the Lenovo Laptop can get connected to the Wi-fi network.
If you’re still having connection problems, try connecting to the Wi-Fi with another device (Mobile phone, tablet etc.). If the connection does not get established on the other device, the problem is most likely with the router or the ISP. Contacting the ISP would be a good option in this case.
If the connection issue is limited to your Lenovo laptop, try the fixes suggested below.
