My HP EliteBook 840 G2 laptop is not able to connect to the WiFi network set on TP-Link Archer C80 AC1900 router either to 2.4 GHz or 5.0 GHz SSID and getting the error "Can't connect to this network" even if the WiFi password is correct or by pushing the WSP switch on the router.
But the laptop does connect to 2.4 GHz or 5.0 GHz SSID set at my Netgear R6220 AC1200 router.
The Archer C80 router also uses the latest firmware (1.10.0 Build 210716 Rel.51301n).
The Wireless network security option is set to WPA2-PSK with AES Encryption (similar to Netgear Router).
The laptop is running with Windows 10 (21H2 OS Build 19044.1415) OS and Intel Dual Band Wireless-N 7265 WiFi card that comes with the laptop and windows 10 is clean installed. Also, the BIOS is updated to the latest version.
The laptop did not worked with the window's default driver so I tried to get the driver (Ver: 18.104.22.168) from the Intel site but still that did not help.
Tried with the default windows driver for the network adaptor - Did not work.
Tried with updated driver from Intel - Did not work.
Removed the device and installed it again - Did not work.
Disabled and Re-enabled the WiFi network - Did not work,
Tried netsh winsock reset - Did not work.
Clean Installed Windows 10 - Did not work.
Tried to Forget (Delete) the Wireless Network profile and tried - Did not work.
But temporarily disabling the Security Key on TP-Link router DOES help the Laptop to connect both 2.4 and 5.0 bands.
Also, setting the Security Version to "WPA-PSK" (instead of default WPA2-PSK) DOES help the Laptop to connect both 2.4 and 5.0 bands.
Please help guide me on how the computer can connect to the WiFi router.
