I travel a lot, and for the past few years the Apple Airport Express has been my favorite travel router, and in some cases it may still be. But for the past few months I've also been totting around a very small and full featured travel router from D-Link. And I love it. The tiny router that fits inside a small case is the D-Link DAP-1350.
Why is it so good? For starters it connects quickly to all kinds of wired networks. It comes with everything you need, all in one case, but most of all is it's range and power. I find that after I've gone out of range of the Apple Airport Express, that the smaller, and lighter, D-Link is still going strong.
As someone who rarely writes a product review, this is one product that makes a road warriors life easier. You can buy it online at Amazon for under $80 USD.
