Hi Musa41111,


Welcome to Lenovo Community!


As per the query we understood that you are facing issue with wifi not working in your Lenovo U330p laptop.


Try to update the driver to the latest version and check for the issue.


Click here for the driver for windows 7


Click here for the driver for windows 8


Click here for the driver for windows 8.1.

  1. Uninstall intel proset/wireless software from windows.
  2. Right click on the windows logo on the taskbar and choose "Network Connections"

4.Right click on Wifi and choose "properties"

5.Click on "configure"

6.On the second tab, change "802.11n channel width for 2.4 GHz" to "20MHz"

7. Activate WMM mode in "Ad-Hoc QoS mode"


8.change "wireless mode" to 802.11g

9.In the last Tab, disable the ability for PC to turn of your wireless device.

10.Dont forget to restart at the end.


Hope this helps. Do post back if the issue persists!


Best regards,
