I have a Lenovo Ideapad with Windows 8. I connected to the WiFi and it worked fine last night, but now it says it can't connect and the other people with me can connect. I have the password correct so I can't figure out what's wrong. I tried rebooting it. It didn't work.

Laptop or desktop can't connect to WiFi problem exists here and there. Fixes are different for different users. Below I will list what I know that help to fix WiFi connection problem. Please add your fix if it is not in the list. Thanks.

Fix 5: Clear Computer Glitches and Change a Wireless Network Card

Due to overheating or old age, computer's network adapter might suffer a sudden failure which results to the network connection interruption. Viruses and worms also may disable or block a computer's network interfaces from functioning properly.

So if there is no way after you contact your internet service provider, try to replace the old wireless network card.

Fix 6: Reset the Winsock Catalog

If you can't connect to the internet and got the message "Limited Connectivity" and "IP4V - No internet access" IPV6 - No internet access", maybe you need to reset the winsock catalog. Do as follows:

1. Run cmd as administrator

  • Start >Search cmd >Right Click "Run as administrator" (Ctrl +Shift + Enter)


  • Start > All Programs >Accessories > Command Prompt >Run as administrator 

Note that if the User Account Control dialog box appears, click "Yes" to allow the change.

2. Input netsh winsock reset, press enter, you will get this dialog box (shown in the below)

3. Restart your computer.
