My xbox 360 slim is connecting via built in wireless to my router in Spain. It is able to connect most of the time to the router AND internet, but not Xbox Live. Sometimes it fails to connect to the internet when testing the connection. I have tried manually setting the DNS servers, but these are the same as automatic anyway. The same settings work for computers in the house to connect, but using a different IP address. There is no problem with the wifi on phones/iPads/laptops/computers.
I have posted an image of the settings below. Please could someone suggest something to get it working? It always says there's a DNS server connection problem, but don't know why?
