airport extender

Unfortunately, Apple's "extend a wireless network" feature is designed to only work between 2 Apple devices.

If you are trying to "extend" using wireless only, there is almost zero chance that this will work with a Belkin modem/router....or any other manufacturer's product.

The Express can be configured to provide more wireless coverage if you can establish a wired Ethernet connection between it and the Belkin product.

I have a Netgear N600 DGND3700v2 dual band wireless modem router.

I created a wireless network with it.

I reset a time capsule and asked it to extend a network. It saw and connected to the Netgear with

ease.

On the wireless network now, I have 1 express to a printer, 1 express to a speaker, 1 apple TV, two imac's

1 extreme, and the time capsule that both imacs back up to.

Time capsule is not connected to anything via ethernet.

I would suggest modern dual band wireless devices using the same format will be able to be extended.

This one was very easy.

I have led you astray above.

I have Joined the netgear network, NOT extended it.

Sorry.
