    It's typically caused by the router not handing out a DHCP lease. If you look at the IP address 'assigned' it will be a 169.254.x.x, which is what the IP stack assigns when there is no DHCP. The issue might be with the router, if they hold onto the addresses for disconnected devices too long they can overrun the address table. Some router designs only allow a few addresses to better handle the traffic load, though most modern ones ought to at least give up to 100 addresses out, if not the full 253 (2-254, 1 is typically earmarked for the router itself).
