No internet on desktop; ethernet or wifi
I was sent a new RG model 5268AC to replace NVG599 which is now 3 years old. Phone rep said issues causing intermittent internet loss most likely caused because old modem. She said modem is supposed to be replaced every (2) two years? Is that true? Anyway, after installing the new modem I can not get DVR connected and 2 of 3 wireless STBs will not connect. In addition my desktop which is connected by ethernet still has no internet connection by ethernet or wifi. I have spent entire day from 12 to 7 PM troubleshooting with AT&T escalation team. Ultimately they decided to send a technician tomorrow. This makes no sense. They said could send anyone today because decision to send a tech made after 3 PM. Everything was tried including swapping out cables. Is it possible I was sent a RG that cant handle my setup? I have 3 wireless STBs, a DVR STB, WAP and VoIP.
