Issue: If your notebook/computer are able to recognize the wireless networks but not able to connect to the wireless networks. Follow the below steps to resolve this issue.

 

Cause: It could be an issue with the Secured wireless network or IPv6 protocol.

 

Internet Protocol version 6 (IPv6) is a network layer for packet-switched internet works.  It is designated as the successor of IPv4. The main change brought by IPv6 is a much larger address space that allows greater flexibility in assigning addresses. IPv6 is designed to run well on high performance networks (e.g. Gigabit Ethernet, OC-12, ATM, etc.) and at the same time still be efficient for low bandwidth networks (e.g. wireless). In addition, it provides a platform for new internet functionality that will be required in the near future.

 

But many routers do not support IPv6.

 

Resolution:

 

Step 1: Disable IPv6

 

1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter

2. Right click on each network connection and select "Properties"

3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)

4. Click OK to exit the dialog

 

NOTE: You should do this for each network connection.
