Ask Computer Networking Questions and Get Answers ASAP
Sorry to hear you are having an issue with your Netgear Nighthawk. I would try to remove the power from the unit for 1 minute, then turn it back on. Then see if your devices connect to the unit again. If they connect again, but the issue persists again after another several hours it may be that the unit is defective. If it does not come back we can try to troubleshoot the unit via a computer connected via Ethernet cable.
