I have a Linksys E3000 wireless router downstairs, with two xbox 360 units hardwired to it. Upstairs I have a Cisco WET200 wireless bridge which connects to the E3000 wirelessly. Upstairs I have two xbox 360 units hardwired to the WET200. The E3000 provides IP addresses to everything. The WET200 just provides a wireless connection to the E3000. Most everything works flawlessly....except system link. The two units downstairs can do system link together, and the two units upstairs can do system link together, but system link will not work between the upstairs and downstairs units.
The only other flaw in this setup is that I am having some connectivity issues when hosting a live Black Ops game upstairs, when the other upstairs xbox360 tries to connect to it. Using Live, I realize the connection has to leave my residence and then come back, through the same e3000 to WET200 wireless connection.
I was trying to avoid drilling a hole in the floor and running a cat5, but it is looking like I may have to anyway. Any ideas on why system link will not work when introduced to the e3000/WET200 wireless connection?
