If the problem is with the PC
- If that doesn't fix the problem, reboot.
- That didn't fix it, either? Okay, time to make sure you're connecting to the right network and using the right password. Click the Wi-Fi icon in the notification area for a list of available networks. Yours should be there, and it should say "Connected," but it probably won't.
- Attempt to connect to the network, and make sure you have the right password. When typing the password, be careful about letters and numbers that look alike. It's easy to mistake the number 1 with a lowercase L or an uppercase I . And an uppercase O can be mistaken for the number 0.
A few other things you might try:
- Look at the bars next to the network's name to make sure you have a strong signal from the router. If you don't, try moving to a room near the router.
- Use Windows' diagnostics. Right-click the network icon in notification area and select Troubleshoot problems. Then go through the wizard.
- Turn off your firewall-temporarily, of course-and try again. If it works, figure out what's wrong with your firewall settings.
If the problem is with the network
Try rebooting the network. Unplug the modem and router, wait a minute, plug them back in, wait two minutes, and try again.
If that doesn't help, try connecting the laptop to the router via an ethernet cable. That will tell you if the problem is with the router's Wi-Fi. If it is, go into your router's settings (if you don't know how, check its documentation) and change the Wi-Fi channel.
