>Why cant i play with the connection true the router?
One of three likely reasons, in no particular order:
1
You have 1 or more other computers connected to the router, and they are taking a lot of the bandwidth. Look out especially for programs like Limewire or Kazaa being run on these computers. Someone else had this problem and discovered that their children downloading music on another PC was the cause.
2
Your router is not very good or not working well. It may be breaking up data packets, which may not be noticeable for other internet applications but WILL cut FoD connections. My previous router did this, and my problems stopped when I replaced it.
3
One of the cables or connections is not good. This can be ANY cable connected the router or your network system. A faulty cable or poor connection will cause a massive increase in network traffic and give you problems. An example is the corporate network I used to work on - we had massive wireless problems in one building and could not work out what was wrong. It turned out that one of the high speed optical cables into a minor server was faulty, and nothing to do with the wireless system at all.
I hope this helps :)
