I purchased an EX6120/AC1200 to extend my NightHawk R8000 router. The first one I got wouldn't connect to the internet at all. I spoke to Tech Support and after running through the same troubleshooting I had already done, they said I needed a replacement.
Got the new one and had issues even running the Smart Setup. Finally got it up and I can only get the 2.4 connection to connect. The 5Ghz side connects to my router, but not the Internet. Steps I have tried:
Updating to newest firmware (Incidentally, I kept getting an alert that there was a new version, but when I'd click on the Update button, it would say it couldn't download the update because there was no Internet. But...Um...I was connected to the Internet using the 2.4 side. So apparently, the extender uses its own 5Ghz connection to communicate with the mother-ship. I ended up manually installing to the latest version .48
Factory reset and walking through the Smart Setup several times.
Tried changing my wifi channels
Tried connecting to both of my 5Ghz Nighthawk channels (It has 2 5Ghz and one 2.4Ghz)
I was 37th in line with Tech Support today, but got through and we went through all the same steps I've already tried. The tech determined I would need yet another EX6120.
Thing is, this problem seems prevalent (just search Google) but nobody seems to have ever found a solution. I'm going to ride this replacement horse until I either get an exteder that fully works, or Netgear fixes this issue.
