Of course, JohnnyDev is correct. I realized that I was giving you the Cliff Notes version which was incomplete.  Apologies if it wasted a bit of your time.

No it was not a wast of time, I still have'nt figured out what's wrong but I will check something today with my internett supplier. I think the problem is within the router I have, I''l will give you feedback a little later.
