Anyone having trouble seeing some AC channels? I had a launch day N5 that had no problem connecting to ch 153 on my Netgear Nighthawk running DD-WRT. I sold that N5 months ago and now have bought another N5. This one won't "see" my AC network unless it's set to a channel under 48. Even wifi analyzer shows that I have a limited 5 GHz channel range. My S4 connects just fine. Do your N5's see higher 5 GHz channels?
See the photo below. I only see my neighbor's wifi 5G network and the graph stops at 44.
EDIT: Fixed it. It seems changing my extension channel has fixed the issue. I now see the network. N5 seems to not support all AC channels listed in my DD-WRT channel settings.
