My own wireless network in my room

Dear all,

Im looking to rehaul my existing setup because its causing me problems. Ive been searching for a long time and I just cant seem to get the answer.

I have a room in a house I share with other people. I want my own network in my room, im not all too fussed if people can see my kit although id prefer they didnt (windows 7 seems to be a bit irritating about this). At the moment all my kit is sort of half between being physically connected to the router in my room and the rest going through wifi but this all has to go to downstairs. It means my squeezebox-PC, squeezebox-NAS and PC-NAS connections are basically rubbish. I want the only bottleneck to be the internet speed to my room. Once its here its cool, everything needs to be smooth IN my room.

Please bear in my I considered the repeater bridge but I dont have details for the modem/router downstairs so I barely managed to get the Bridge going with dd-wrt. I also dont want a repeater because then the rest of the house will be using my router instead of the one downstairs.

I currently have this setup:


I want this:


Its effectively taking internet wirelessly as it does now but under a separate SSID creates a whole new network for my room only. The router in my room is a TP-Link WR1043ND so I imagine shouldnt be a problem, though it might involve getting another router and fiddling with the IP numbers to get it to work properly, im medium experienced in this stuff no superstar.

Very keen to hear thoughts. It must be a common problem!
