Random disconnects with wired connection in DumaOS on NETGEAR Nighthawk Support Posted March 21, 2018 Noticed my XR500 has randomly lost connection for wired devices at random times. Wireless will remain working. After a quick unplug of the power cable it was instantly fixed but it seems weird to randomly turn off like that. Not sure what the issue is, other than that I've had no issues. Side note, is there a reset function on the DumaOS? I can't seem to see or find one anywhere.
