I've got a 1+year old WZR-1750DHP that has been working flawlessly.
A couple of days ago, my wireless thermostat, and all but ONE of my wireless cameras, decided to go offline.
No matter what I do, they just refuse to light back up. I've since flashed the 1750 to DD-WRT v24-sp2 (06/23/14) std - build 24461, still no joy.
Using a wireless sniffer, I don't even see the second network (the 2.4ghz).
Has anyone else experienced this issue?
