Extended Wi-Fi station-after Clicking to manual it as if I want to switch networks? what do I do?

Say no. if that fails and you cannot complete the setup.. do it again and say.. yes.

🙂 This is called suck and see method. 😁

Ah well I got it the wrong way around.. Thanks.. Bob..

Still it takes less time to test wrongly than to post on the forum.

in Extended Wi-Fi station -After clicking on Manual Setup, it ask if I want to switch Networks?

Say "Yes". You have to switch networks to be able to configure the AirPort Express.

If you say "No", you will not be able to configure the Express and the setup will be cancelled.

Once you configure the Express to extend and have a green light, simply log back in to your normal network.
