Last week I came back from my holliday and all of a sudden my XBOX won't connect to XBOX live anymore. It seems like it doesn't pick up the IP-adress assigned to it by my router (my router assigned 192.168.1.121) . I tried using an other router (airport express) but without success. When I use my IPhone as a hot spot I am able to connect to XBOX live. After my holliday I applied the necessary updates and I think that this may caused the issue.
A wired connection to the same router does work!
