ClearAccess (Modems/Gateways) SR 300N: How to filter a MAC address
If you check the configuration of your router, you might find a setting where you can set up the WiFi network to only allow certain devices according to their MAC address.

Depending on your router model, you might find that setting under the WiFi settings or the security settings.

I recommend to disable MAC filtering.

If you didn't have MAC filtering enabled in your router, the console might erroneously detect that. Try to connect the console through an ethernet cable for testing purposes. If that works, disconnect the cable, and try to search for WiFi networks again.

Make sure that you enter the passphrase for your WiFi correctly, as this is not a password that denies you access to the WiFi, but is instead a passphrase used to decrypt the encrypted WiFi traffic. So you could still connect to your WiFi with a wrong passphrase
on some routers, but the console will only receive encrypted data garbage.
