When you are not able to connect to your Wi-Fi connection on a Windows PC or Laptop, try these fixes
- Wi-Fi switch/adapter disabled: Most laptops have integrated Wi-Fi adapters hence make sure the Wi-Fi switch is ON and the Wi-Fi adapter is enabled under Network Settings. Once you turn this ON you should be able to see the list of Wi-Fi networks around your PC/laptop.
- Security key is incorrect: Make sure the security key is correct. You can view the password by selecting the eye like icon next to the password after you have entered it. Sometimes we type the password with CAPS On or with a different language keyboard.
- Restart the PC/laptop and router: Simplest solution for most of the connection issues.
- Similar SSID already exist: We might have used a Wi-Fi name and password previously which is conflicting with the existing wireless name. Press the windows key together with letter I to go to Settings > Network & Internet > Manage Wi-Fi settings. Select the similar network and choose Forget. Retry the connection to the Wi-Fi.
- Static IP on Wi-Fi adapter (Rare but possible): In case your laptop was used by a techie guy who happened to set a static IP on your Wi-Fi adapter. In such cases your computer will try to connect to the adapter but will not receive an IP address. Hence it might show an error as Unidentified Network- No internet access. Simply change the IP setting to Automatic under IPv4 properties and you should be connected.
- MAC filtering enabled: If you own the router then log in to the router and remove the MAC address from the block list.
- Limited scope DHCP server: This happens when the router is set to give out limited IPs in the Wi-Fi network. Hence no new connections will be accepted until the lease time has expired. You can log into the router and increase the scope of DHCP server.
- Wi-Fi adapter drivers: Make sure the Wi-Fi drivers are up to date. You can check the support site of the device manufacturers for the latest updates.
- Router Firmware: Router manufacturers keep releasing the updated firmwares to fix the issues related to its functioning. Visit the support site of your router manufacturer and check for the recent firmware updates, then download and upload to your router.
