WiFi "WPA3" Connection Issues
4.5
Your new router has WPA3 security, but your older devices cannot connect to it.
Symptoms
- Cannot connect
- Wrong password error
- Network not found
Possible Causes
- Device doesn't support WPA3
- Incompatible handshake
Step-by-Step Fix
1
Enable "WPA2/WPA3 Mixed Mode"
In router settings, allow older devices to use WPA2 while newer ones use WPA3.
2
Update Device Firmware
Some older devices received WPA3 support via software updates.
3
Forget and Re-add Network
Forces the device to negotiate a new security handshake.
When to See a Technician
WPA3 is much more secure, but many devices made before 2020 don't understand it.
