Common Wi-Fi issues and solutions

There can be many reasons why your Wi-Fi network can seem to suddenly disappear or not appear at all. If you don't see your Wi-Fi on the network list, here are some possible reasons:
1. Your Wi-Fi switch is off:
If you can't see a list of available networks, Wi-Fi might be turned off.
To turn on Wi-Fi, select the Network icon at the bottom right-hand side of your taskbar. If the Wi-Fi quick action is gray, select it to turn on Wi-Fi.
2. Your device is in airplane mode:
If airplane mode is turned on, Wi-Fi is turned off, and you won't be able to see any networks. Turn off airplane mode and try to connect to Wi-Fi.
3. Your computer doesn't support the frequency that your network is using:
Your device might only support the 2.4 GHz frequency band, but your network is using the 5 GHz band. What's the difference between the two? The 2.4 GHz frequency band is typically slower, but it has a longer-range than the 5GHz band. The 5GHz frequency band is a typically faster and has less interference than the 2.4 GHz band, but it has a shorter range. For best connectivity and reliability, choose the 5 GHz network if it's available.
4. Your router has a problem:
For wireless router issues, you might need to reset your router. Please check instruction on the router or contact your service provider.
5. Weak signal or it's not strong enough:
If the signal isn't strong enough, you will face connection dropping issue or even no connection at all. Some tips for weak signal :

Try moving your router to a different place

Try to adjust device antennas (if any) at an angle to get a better signal

Try to keep your router in an open space which is not far from device

Try Windows built in troubleshoot

Try to update network card's driver software (advance level)
