For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid.
Is something interfering?
