Sure, should work. I already had a Netgear wireless hub. I bought a Buffalo wireless access point, similiar to the product you've shown, at Best Buy. The instructions and the setup program connected me to the Netgear in about 10 minutes. Then all you need to know is the IP address of your Neptune and Voila your set. Easy breezy, lemon squeezie!
However, to use the aquanotes you have to buy the upgrade, the free version can only be configured to the serial cable. Unless one of you computer genius's know something I don't.
