Connecting My Book Live Duo directly to PC

Sure, i hope that you will get the configuration right.

I have good experience regarding price and very easy user configuration with netgear products (the hardware is not the best, but the job gets done). So maybe you take a look at:

I dont know this particular product, the only thing i was looking at was a 4-port Ethernet switch with 1Gbps and n-standard Wifi (and sorted by price). You can also buy any other Device with these two features. There are also other nice things availible like USB for printer, or compatibility with tomato firmware(for advanced stuff).
