Just a word on wireless.... dont use it if you're going to be transferring large files.
Typical Cat5 cable is around the 80-90mbps (even tho it says 100 - 100 is only the "theoretical max").
Wireless on the other hand... there's different speeds again.
You have 10mbps, 22, 54, and i think there's also a 76 now too?
anyway.. my friend has a 22. the max he can get is 11mbps. i have a 54 - the max i can get is 19-20. and no, this is not just bad settings. what they say is that "54mbps" is only theoretical - its actually not obtainable - they even admitted that to me in the end. was not impressed
anyway...back to the point. even at 20mbps... are you sure you'd want to wait 15 minutes to transfer something rather than 3? no..i'd say not
