This router has unstable 5Ghz wireless connections. The 5Ghz signal is very strong when it works, which is good, but I've had the entire 5Ghz network simply vanish from the firmware page which required a hard reset to fix. Other times the 5Ghz networks will just stop functioning, not showing up at all. The Firmware for this router needs more work. To perform a hard reset, keep the router turned on, use a paper clip and insert the end into the reset hole 'small hole on the back of router', hold reset button down for thirty seconds, holding button down, unplug from power and turn off with switch on back of router, release reset button, plug power back in after another minute or so and turn back on. This should fix most issues with 5Ghz wireless signal disappearing or vanishing.
