Windows 8.1 Wifi showing "limited" or "No Internet Access"

Note: First create a system restore point.

Then right-click the ’Start’ button to access ‘Control Panel’ option and select it.

Next, chose ‘Device Manager’ option.

Next select ‘Network Adapters’ and under it, you will find a Wi-Fi controller listed. Select it.

Right-click the controller and click the ‘Disable’ button and hit ‘Ok’ to apply the changes. See if it helps. If it does not help, re-enable it and proceed to the next step.

If the above steps not working, then try doing the following.

Open an admin-level command prompt in Desktop mode, type the following commands, and hit Enter after each command:

Code: netsh int tcp set heuristics disabled

Code: netsh int tcp set global autotuninglevel=disabled

Code: netsh int tcp set global rss=enabled

Then type the following and hit Enter, to verify that practically all the settings are disabled.
Code: netsh int tcp show global

Finally, reboot your machine and see if this helps.
