Two routers, many computers, loads of files, sharing

[lab4]

Ok, let me start with the facts.

I have one main PC with a whole host of drives on it. 6TB or so of music tv shows and films, as well as work files.

I have just bought the components to build a new pc for the garage to act as a box in there.

I have my usual broadband wifi in the house.

I have moved the storage to the garage unit and leave it on 24/7, i have tried copying files from it to main pc via homegroup but speeds are appalling slow. I have tried streaming files from garage pc to main pc but speed hampers any playback.

Router is a sagem N. Computers are about 4m away from each other with two walls in the way on the same floor. Both computers are max 7m away from router with 2 walls in way.

What is the best way for me to use the computer in the garage as a NAS, without it being a NAS, ie i need it to still be usable itself to play the content and music as a windows 7 box.

I have a spare router that could be used specifically for the homegroup, but would this then cutout the internet connection to the main router?

Would setting it up as a network drive be the solution?

Networking is not my strong point, so please treat me like a novice and recommend things and i'll let you know if i've tried.

Many thanks.

Ok, home plugs are an option as is the switch.

What would i do with the switch? Where would it go? What would be plugged into it?

That seems from what you have said to be the most efficient way of doing things.

Ok, many thanks for the proper responses, so my final thicko question....

Do i need the computers hard wired with network cables to the switch, or just the router? Ie can the computers remain wi-fi but with switch in place it will speed everything up?
