How to Fix Limited Wi-Fi Connectivity Issue in Windows 8.1
Users who have upgraded to Windows 8.1 may face "No Internet Access" or "Limited" connectivity issues with Wireless internet connection. First thing to try out to resolve the issue is to rollback drivers to an older version (Manufacturers Drivers) instead of the ones installed with Windows 8.1 by Microsoft. Follow the procedure below:
Go to Device Manager
Go to Network adapters and expand it
Now from the list, choose your network adapter (Wireless Network Adapter) that is showing limited connectivity.
Right click on your wireless network adapter and choose Update Driver Software..
A new window will open, in which you are required to click on Browse my computer for driver software.
On next step, select, Let me pick from a list of device drivers on my computer
Check the Network Adapters, and see how many are listed. You may find two drivers here; one by Microsoft and other from the Manufacturer.
Choose the Manufacturer’s drivers and select Next.
Upon completion, you are advised to restart your PC and check if your problem is solved. If not, proceed with next step.
Another good fix to address the issue is to disable the TCP settings. Do the following:
Open command prompt with administrative rights
Type the following commands and hit enter after each command:
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
To verify that these settings are disabled, type
netsh int tcp show global and hit enter
Once done, you are advised to reboot your system. This should resolve the problem.
