One of the more common failures in older routers is IP service dropout, particularly if the router overheats because something was stacked on top of it. This will result in client error messages such as the one you describe. Another possibility is an authentication failure, but that would generally mean somebody messed with the wireless network access password, or there's a bug in the wireless coding (as in some ASUS laptops - this was fixed in a firmware update).
