Since both WiFi and Ethernet fail, it looks to be more of a server issue or maybe DNS.
Let's google this.
That shows this is well discussed. I don't see anything more I can add to the prior discussions.
I have a cd copy of assassins creed 2 that's been sitting for a few years and I decided to play it. I installed the file but when I open it, it says it cannot connect to Ubisofts master servers. My wifi connection is stable and Ethernet didn't work either. Does anyone know how to fix this
