How To Fix WiFi Issues in Windows 8.1

Reader Question:
“Hi Wally, My computer’s wifi is not working since I upgraded to Windows 8.1. How do you normally fix wifi problems like this?”  - Marissa E., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: In today’s connected world having access to an internet connection is a must. With laptop sales booming and with the increase in the use of portable technology, most devices are using wifi to connect to the internet. If you are having problems connecting a Windows 8.1 device to a wifi connection, try the following:

Connecting to WiFi Internet in Windows 8.1

Windows 8.1 connects to the internet when it starts. If your computer does not connect automatically, do the following to fix wifi issues:

  1. Press Windows Key + I on the keyboard.
  2. Click Network > than click the Wifi on\off switch

Router and Wires

Make sure that the router is running and the lights on it look normal. e.g. the Power (Power symbol) light should be on, and the Internet (Globe symbol) light should be on (depending on manufacturer it might turn on when data is being transferred). Also make sure that the router’s wires are properly connected. As a last resort you can press the factory reset button of the router to reset all of its settings. This may or may not allow you to connect to the internet through wifi without setting up the wifi first. In that case you will need to use the router’s IP address and log in to see its settings and change them.

Troubleshooting TCP/IP

This is the first thing that you’ll need to check if the router and wires are okay. Windows has a built-in utility (netsh.exe) designed for this purpose.

  1. Press the Windows Key and type cmd.
  2. Right-click Command Prompt from the search results and click Run as Administrator.
  3. Type netsh int ip reset c:\restlog.txt and press Enter.
  4. Type netsh int tcp set heuristics disabled and press Enter.
  5. Type netsh int tcp set global autotuninglevel=disabled and press Enter.
  6. Type netsh int tcp set global rss=enabled and press Enter.

This prevents Windows from auto tuning TCP/IP settings on its own, and should prevent Windows 8 from changing any settings on its own.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
