AT&T Tech said modem Model NVG510 (1/12/2015) is also a router? he gave me a Netgear WN3000RP-2A1NAS to boost signal to park!? Looking for suggestions on reasonably priced equipment and set up for wireless for 16 site RV park with line of site from office to park. Unfortunate issue is only able to get 3.6 megs due to distance of wire ( but better than the satellite system was having to use).
