C6300 drops connection

So I have a Netgear AC1750 C6300 and for some reason it drops all devices when I attempt  to connect my desktop via Wi-Fi. The desktop will only connect for a minute or two and then disconnects kicking all my devices off. I have no issues with the devices connected directly into the modem though.  When I do try to connect via ethernet it still kicks off the Wi-Fi devices. I have tried factory resetting both my desktop and my modem, which have not worked. The desktop used to be able to connect via Wi-Fi with no issues before, not sure what happened since I made no changes to the settings or anything. Not sure what to do or try since like I said, the issue seems to be only when I attempt to use my desktop.
