|Everything is fine, until we added two new turtle beach wireless headsets. Then the xbox's get kicked from the network and lose connection to xbox live|
This could be interference cause by sharing the same channel or frequency with other devices like cordless phones. Microwave ovens can also interfere with wireless as can other things.
Only other idea would be to hardwire the house, and thats a little expensive.
If you did it yourself, you could do it fairly inexpensively and in my opinion it would be worth it. Plug all PC's, laptops and gaming consoles via a network cable and reduce the number of wireless devices you have going on in your home. I'm sure that would help a lot.
Punching down cables isn't that hard and you can google the standards. All that's required is a punchdown tool, a patch panel, faceplates and RJ-45 keystones to snap into the faceplates.
As a long time gamer and experience network technician, I would rather not game than game over wireless. At least where bandwidth intense games like FPS's and strategy games like WoW or Company of Heroes goes. The wireless seems to work ok when I race Mario Kart on the Wii, but I know from experience games like the ones I mentioned don't perform well over wireless due to it's inherent susceptibility to lag and latency.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
