I've long been a fan of Buffalo's dual-band wireless routers (I run three of them in the house and office) and now Buffalo has shown (and is about to release) a dual-band, 802.11ac-capable, portable wireless travel router. The AirStation AC433 (model WMR-433) is a tiny, two-inch square device that plugs into your hotel Ethernet and then shares the connection to all your devices over either 5GHz or 2.4GHz Wi-Fi. It's built to be set-up once and then just work in whatever hotel room you're in. It can reach speeds of up to 433 Mbps on the 5 GHz band (hence the model name) and 150 Mbps on the 2.4 GHz band. The band is user-selectable via an on-device switch allowing the user to choose which is best (and, in most hotels, 5GHz is where we'll find the least contention). The AirStation AC433 is due out in April and will be available for a street price right around US$50.
