WiFi works on some devices but not others
The router's security type probably changed and your older device doesn't support it. Change the router from WPA3 to WPA2/WPA3 mixed mode. This lets old devices connect.
Newer routers use WPA3 security but older devices only know WPA2. Your router is set to WPA3-only, so newer devices connect but older ones can't. Changing the router to mixed mode lets both work.

⚡ Before you start
- ✓List which devices work and which don't. Are the ones that don't work older?
- ✓Check if your failing device is old and only supports 2.4 GHz band
- ✓Check the current WiFi security setting on your router (WPA2, WPA3, or mixed)

Skip, I just want a technicianCommon mistakes to avoid
- Assuming the broken device is the problem when it's actually the router settings
- Factory resetting the router which disconnects everything without fixing the real issue
- Not checking if older devices need the 2.4 GHz band specifically
Signs you need professional help
- Changing security to WPA2 mixed mode doesn't help and devices still fail. Multiple old devices fail and you want a setting that works for all of them.
