Got new Nighthawk data and voice modem that has no WiFi capability. Comcast hooked it up for me, tested signal, it is good for my Eero system that worked with older Arriss Router Modem combo, but I can not get it to work with the new Data only Modem, planning to use Eero as Wifi Internet Access. I only get LAN to my ancient Win7 PC so far. Help?
