Apple has really made setting up a wifi network easy. Airport Utility now requires only a few clicks, and correctly guesses what you want to do with each device.
When they start adding devices, or reconfiguring existing ones, many people are reluctant to wipe the routers and start from scratch, but that’s totally the thing to do. It saves a ton of time and guesswork.
Here’s how you do:
- Reset both devices to defaults
- holding the reset button with a pen til light blinks faster
- Unplug your internet modem from power, count to 5, and plug back in.
- Set up the Airport A connected to the internet.
- Use the same settings, including wifi network name.
- Make sure you can now surf the web.
- Plug in Airport B, in the same room as the first one.
- Configure B, letting Airport Utility guess correctly that you want the B to extend A.
- Once both are green, unplug B, and plug it in where you need it.
- Make sure it goes green, and you can surf in the G’s office.
