Thanks James Kendrick for your comments about ZyXEL AG-225H WiFi Finder. It combines a 802.11a/b/g USB 2.0 adapter with a fully functional wireless hotspot detector in a sleek device small enough to fit into any pocket. I haven’t used one yet, but can imagine where I will as I travel.
I prefer to use Netstumbler 0.4.0 on my tablet since I’m too cheap at this time to buy another gadget. But I like gadgets, so I’ll probably get one someday – I’ll be able to keep my tablet off when searching too.Of course you won’t need one in Portland soon, just an account here or here….or maybe not: here
