New Wireless setup needed

[Sparky]

Finally moving over to a wireless network for the 4 devices we have in the house. We have 3 Shuttle PC's and a Buffalo Link Theatre that need to be connected.

Can you explain to a "Wireless" noob what i need to buy and recommend a system please.

Im on NTL cable.2 of the PC's will need USB Dongles as they are upstairs, 1 is right next to the router and the 3rd device is the Link Theatre.

Bearing this in mind i think some routers have a hard wired output via Ethernet? Correct me if i am wrong.So that only leaves the connection to the Buffalo.Need to find out what wireless setup that supports failing that i could buy a 3rd USB Dongle for the PC downstairs and hardwire the Buffalo.

What you think?

Yeah sounds good, tho id get a PCI card instead of the USB dongle i possible

The PCI cards more reliable?
