Hi,
I thought perhaps it would be a good idea to have a thread for people who have found and are using eXtended Range adapters that are working well with our Zs.

I just picked up this USB adapter which supports the eXtended Range Technology in the Z, and am able to get an excellent signal to a building on our property, where I had a low and barely usable signal before using a different adapter that doesn't support eXtended Range Technology.

This works excellent with the Z! IT's an Engenius Tech EUB-362 ENT.

If you do a search you can find it online selling for a little over $40 American. As well as working awesome with my router, I have also been able to pick up 4 additional APs I couldn't see before....this is a nice little unit!

Trendnet sells what appears to be the same USB adapter rebranded as a Trendnet as well which you can find here:

Please feel free to add your own find of Wifi adapters, so we can have an online resource for folks who may be looking to reap the benefit of the eXtended Range Technology built into their routers, and can't find USB adapters to work with them.
