Why won’t my PC connect to Wi-Fi after a restart?
If your PC won’t connect to Wi-Fi after a restart, it’s likely due to a temporary glitch or a minor issue with your network adapter. Try restarting your router and modem to see if that resolves the issue. Unplug the power cord from both devices, wait for 30 seconds, and then plug them back in. This will reset your network and may resolve any connectivity issues.
If restarting your router and modem doesn’t work, try disabling and re-enabling your network adapter. To do this, go to your PC’s Device Manager, find the Network Adapters section, and right-click on your Wi-Fi adapter. Select “Disable device” and then wait for 10 seconds before enabling it again. This will reset your network adapter and may help you connect to Wi-Fi.
How do I troubleshoot Wi-Fi connectivity issues on my PC?
To troubleshoot Wi-Fi connectivity issues on your PC, start by checking your Wi-Fi settings to ensure that Wi-Fi is enabled and you’re connected to the correct network. You can do this by clicking on the Wi-Fi icon in your system tray and selecting your network from the list of available options. If you’re still having trouble, try restarting your PC and router to see if that resolves the issue.
If restarting your PC and router doesn’t work, try running the Windows Network Troubleshooter. To do this, go to your PC’s Settings app, click on “Update & Security,” and then select “Troubleshoot.” Click on “Additional troubleshooters” and then select “Network Adapter.” Follow the prompts to run the troubleshooter and see if it can identify and fix any issues with your Wi-Fi connection.
Why is my PC connecting to Wi-Fi but not accessing the internet?
If your PC is connecting to Wi-Fi but not accessing the internet, it’s likely due to a problem with your internet service provider (ISP) or a misconfigured network setting. Try restarting your router and modem to see if that resolves the issue. If you’re still having trouble, try checking your ISP’s status page to see if there are any outages or maintenance in your area.
If restarting your router and modem and checking your ISP’s status page doesn’t work, try resetting your TCP/IP stack. To do this, go to your PC’s Command Prompt and type “netsh int ip reset” followed by “netsh winsock reset.” This will reset your TCP/IP stack and may help you access the internet.
