Wireless rocks.. I originally had a LinkSys Wireless ROuter, which worked alright, but couldn't reach the porch and certainly never made it to the far corners of the house.
I snagged an Orinoco (made by Lucent) kit off of ebay with an AP-500 access point and two gold cards (128k encryption) and installed it in the attic, with the ethernet snaking down to the rack in the basement).. now this stuff reaches clear across the street to the neighbors... it's awesome...
My fave though is taking the laptop out to the local starbucks and working from there
