Wireless/wired solution that is gaming friendly

alright guise,
I have a detached garage with an apartment above it. I have a linksys wireless g router all the way on the opposite side of the house, meaning the wireless signal doesn't reach out there. I want to have an internet solution without having to buy another modem and that is gaming friendly (ie won't cause excessive latency, good dl speeds, etc.).

when latency is more important like games,
then avoid , avoid and avoid wireless.

either ethernet cable, first choice

or Home Plug, second choice.

I guess it depends how hardcore your gaming is. Some wireless router manufacturers are starting to do the gaming thing. For example Netgear advertised the WNDR3700 as the ultimate gaming router.

I wouldn't disagree with Wayne that a gigabit ethernet wired connection all the way is the best solution, but if you don't want wires through your house or to use your electric supply, then a full wireless N network all the way may still cut it. Though I do come back to my opening caveat - if you've got a monster gaming rig with a £500 video card, bigfoot networking, etc then you'll want the Gigabit wired solution.

Hope this helps
