+1 on what's been suggested. If you have an 802.11 b/g card, and your Extreme is set to N only, it's not going to work. Also, make sure you don't have closed network set on your airport extreme. That will work of course, but you'd have to type in your SSID and it wouldn't show as available in the airport client on your 10v. You would find that setting under Airport, Wireless, and Wireless Options. One other thought, the latest airport extreme (which I don't have) can also broadcast at 5Ghz, 2.4Ghz, or both. Your card on the 10v will only work at 2.4Ghz, so check that any settings for that too in case you have the latter. I've only seen the specs and have no experience with the latest model so it may work a little differently than I've described.
