[atlas] v3 probe has gone offline and can't be revived

My v3 probe took itself offline earlier today and attempts to get it back online again haven't worked, after booting it settles into a state where there's no ethernet connection to the router it's attached to, the Power LED is on (obviously), Internet is off, WiFi is blinking slowly, Ethernet is blinking quickly, and WPS is on. Trying to factory reset it has no effect. Does anyone have any ideas on where to go from here?
