problems with cable, grandstream, apple extreme base station
i have cable for isp on my imac. phone power service and a apple extreme base station for my wireless network. how do i get these three to communicate right. when wired phone power does not work. it just says not registered when i try to call out.
My setup is cable modem > airport extreme > grandstream into one of the 3 ports on back of airport extreme. All works with no issues.
Unplug everything, start cable modem and let it sync completely, plug in airport extreme and wait for front green light to start flashing, then plug in the grandstream.
