A recent thread here discussed whether the Centrino chipset is perhaps inferior to other Wi-Fi implementations on laptops. I've got pretty solid evidence that that notion is false. I've been doing Wi-Fi in my home for a couple of years now, with generally good results. However, whenever my wife uses our Panasonic 2.4 gigahertz cordless phone, my laptop loses its Wi-Fi link. The microwave oven also causes interference, though usually not enough to kill the connection. I've tried everything. I've used Linksys, Microsoft, Intel, and D-Link Wi-Fi PC cards. I've changed channels. I've gone from 802.11b to g and back. I've called Linksys, whose tech support guy laughed out loud when I told him I was trying a Panasonic cordless phone with Wi-Fi. (The implication was that Panasonic does not play fairly in the 2.4G sandbox.) Last night I tested an IBM Thinkpad X40 at home. It instantly connected to the home network, and its connection survived a Panasonic attack, whether the phone was close to the laptop or away. The computer also detected a neighbor's network that previously only showed up when I wandered into an upstairs bedroom close to their house. My conclusion is not that Centrino is superior, but rather that the built-in antenna in the back of the LCD screen is far superior to what you can cram onto a PC card. In any event, Centrino does not appear to be a point of weakness. /rich
