Instant Wi-Fi

D-Link Pocket Router

If you travel a lot, you’ve probably encountered a hotel, convention center, or remote office that supplies an Ethernet jack rather than Wi-Fi. That’s generally not a problem. Most notebook computers can handle both types of Internet connections.

Sometimes, however, I prefer to connect over Wi-Fi. I might want to use my notebook away from the desk in the hotel room. Or I might want an Internet connection for my iPod Touch or BlackBerry Curve — both are Wi-Fi enabled.

Being able to connect a Wi-Fi enabled phone can be especially handy if you’re traveling outside the country, and your phone isn’t compatible with local cellular standards. With a Wi-Fi phone, you may be able to make and receive calls over Wi-Fi using your regular phone number and be charged as though you’re making a local phone call.

So how do you convert an Ethernet jack into a Wi-Fi access point? You can use D-Link’s DWL-G730AP Wireless Pocket Router. It sells for about $50, comes with a durable carrying case, and supports three wireless modes: Router, Access Point, and Wireless Client.

Set up can be a little tricky, as the documentation isn’t as clear as it should be, though once you have it configured with your Wi-Fi-enabled devices, you can just plug it in and connect. (For tips on configuring the DWL-G730AP, check the comments section for the product on Amazon.com. Here’s a link to the review there that helped me configure it as an access point. Unfortunately, I can’t offer advice beyond that.)

The DWL-G730AP can handle multiple connected devices at the same time, so you could provide Internet access for family, friends, or co-workers. WPA security is built-in, and you can hide the SSID as an additional safeguard. You could configure the SSID and password for your own devices before the trip, and then supply that information to others while traveling.
