I just purchased a Netvanta 3448 to power a small local network that will include a Jive VOIP installation; the AP's I purchased are 160's, two of them. I now discover I need a separate, as yet unidentified, controller for the 160's. Isn't AP control built into the AOS in the router? If not, are there lightweight Netvanta AP's that would work without a need for a separate controller?
