My only options would be :
1) Turn my own router as a bridge (So it acts as a modem only) and not use a dailer.
2) Bring in a modem that is no router by default
3) Bring in another router and try the same thing.
4) I have ordered a new Ethernet external card yesterday, so it'll be arriving within the next few days. So i will have 2 "Local Area Connection" . Will see if it has anything to do with the interface itself (Even though the fact i use an external USB for wireless already false this statement, but then comes in the fact the game doesn't like extra USB devices - So will try it out with a whole different hardware in the ethernet field)
Unfortunately not today already as it's 1 AM - And work tomorrow morning again so i am very sorry but will have to do the first three steps after work tomorrow and the whole thing will have to wait till then
