I was wondering about two switches. One off the marconi for tv, and 
the other to share internet.

If it works, then I will stop fiddling with the router.

I can't remember the exact prices, but I saw XBoxes, at EB Belconnen 
at around $224 on the weekend. I suppose places like Big W will have 
them slightly cheaper ie $2 less so they can claim to be the cheapest.
