Get Connected

Be Productive



From Bradley Mitchell, your Guide to Computer Networking
It's not much fun to be kicked out of class, a shopping mall, or a club. But being booted off a computer network these days has become a major impact on people's productivity. Just ask some developers of Wi-Fi stumblers and Sandy Gibbs' daughter (see below), or Jennifer (see sidebar).

Apple Bans Some Wi-Fi Stumblers from App Store
They are alternately called stumblers or sniffers or finders. Whatever the name, Apple has decided that some of these helpful Wi-Fi network detection tools no longer belong on its App Store. Here's an explanation of why.

DISCUSS: Temporarily Disabling Wi-Fi at Home
Sandy Gibbs is one of readers who sometimes needs to turn off their home's Wi-Fi network temporarily, for family disciplinary reasons. In effect, banning their teenage daughter from getting online. Is there an easy way to manage this? Our readers have a few suggestions.

POLL: Do You Allow Neighbors to Access Your Wi-Fi?
Some people open up their wireless home network to share with neighbors despite the obvious security risks. Two years ago when we polled our audience, about 50% of the respondents indicated they had logged into their neighbor's Wi-Fi at least once! No doubt some of those visits were made without the owner's knowledge. Do you actually allow this kind of access into your home network?

What Is My IP Address?
A network may contain multiple computers or others devices each having their own IP address (or addresses). Answering the question "What's My IP Address?" depends on exactly which IP address you are looking for.
