As much as I love the idea of wifi, in reality I'm not that much less tethered to my wireless router than I'd be with a regular cabled connection. I can't seem to wander much more than 20 ft. or one wall away before I start losing signal strength. And the only time I've ever come into contact with a free workable "hot spot" is my next door neighbor's connection in my own house. Oh and the CVS connection that I occasionally, frighteningly get through on. But that's cool, I like knowing who on my street needs anti-psychotic meds.
Belkin's new Pre-N, MIMO wireless routers offer four times the speed and coverage area of 802.11g and better resistance to interference from other signals like the cordless phone. It's backwards compatible with 802.11g and 802.11b equipment. It's a little pricier than most wireless products ($180 for the router, $130 for the notebook card) but if it can deliver coverage that actually lets me climb the stairs without losing my connection, it'll be well worth it.
Available in October from all Belkin resellers.
