If you are a Windows 8 or 8.1 user, you may have come across the message that notifies you of issues to connect to your wireless network. The message simply lets you know that there is limited connection or no connectivity at all, but it doesn’t provide any additional details, which leaves you in the dark. Not having internet access can be incredibly frustrating when you need to send an urgent email, or when you want to use instant messaging services to wish a happy birthday to a friend or family member who lives far away.
The fact that the Windows message doesn’t provide any details about the cause of the problem, only adds to your frustration. You can spend hours trying to fix the connectivity issue and to make things even more confusing, sometimes the error message appears even when the signal strength is displaying five bars, which should indicate that your connection is working well. The majority of users who face this problem, opt for disconnecting and reconnecting, while others go as far as trying to uninstall the network adapter. However, there are other effective techniques that you can try. Here are some alternatives to fix the Wi-Fi connectivity issues in Windows 8.
Allow download over metered connections
This option will work if you are using your smartphone as a mobile hotspot and it would fix the problem even if you are not using a metered connection. To enable the “Download over metered connections” option, follow these steps:
1. Press the Windows Key + w and type: metered connections
2. Once the Devices screen is selected, you will see the “Download over metered connections” option. Toggle it to On.
3. Sign out and then login to your computer. The changes should be applied now.
Netsh.exe to the rescue
Resetting TCP/IP stack to its default configuration with the help of netsh.exe, is one of the easiest ways to tackle the problem. The command netsh.exe refers to the NetShell utility, which is an incredibly flexible tool that enables you to control a wide range of computer processes from the command line. You can use NetShell to solve the connectivity issues, following the below steps.
1. To launch the Command Prompt with administrator rights, press Windows Key + x + a.
2. When the black window appears, type this command: netsh int ip reset C:\resetlog.txt
3. Reboot the computer and retry the internet connection. You should not experience issues this time.
Time to wake up the Wi-Fi Adapter
The connectivity issue may be caused due to the network adapter going into a sleep mode in order to save energy. You can try this when other options don’t seem to work, or when they only solve the issue temporarily.
1. Press Windows Key + w to launch the Settings search box and enter the following: network and sharing center.
2. Click the name of your Wi-Fi network and select Properties, the button that appears in the lower left corner.
3. This will lead you to the Wi-Fi Properties window. Click the Configure button that appears there.
4. In the next window, select the Power Management tab and uncheck the box next to “Allow the computer to turn off this device to save power”. Then click OK and login to your computer again to verify that the issue has been fixed.
Reset TCP/IP Autotunning
Autotunning modifies the congestion buffers to enhance the reliability of the connection. Resetting it with netsh commands is another method that may help you to solve the connectivity issues. Windows sometimes applies random changes to the size of the TCP buffers. By executing the commands below, you can change the TCP Windows size and this adjustment would be reinforced, stopping Windows 8 from messing with it again. Keep in mind that this is an advanced solution and it is advisable that you use it with caution, as it may crash other processes running on your computer.
The first command you can try is netsh int tcp set heuristics disabled. This command disables the scaling window in TCP following the second re-transmission of a SYN packet. The other two commands are: netsh int tcp set global autotuninglevel=disabled and netsh int tcp set globa rss=enabled.
If you are experiencing limited access issues with your Wi-Fi network, rebooting or reconnecting would be the first choices to try to get back online, but if they don’t work, you can try any of the methods outlined above to reconnect to internet.
