AT&T boosts cell data speeds

AT&T said it updated its 3G wireless network to reach download speeds of up to 1.7 Mbps.

AT&T's laptop users get free Wi-Fi, but only on Windows

AT&T extended free access to its Wi-Fi Home package of U.S. hotspots to monthly, unmetered subscribers to its broadband subscribers -- but only via Windows software.

Starbucks network switch has begun

Review: Time Capsule Wi-Fi base station

Thanks to a timely software update, Apple's Time Capsule is an easy-to-use backup appliance that provides speedy wireless network access while keeping your data safe.

Hands on with Time Capsule

Glenn Fleishman digs into Time Machine, getting some initial ideas about how it performs, and uncovering an unexpected feature.

File sharing in Leopard

If you want to share files with other people (and who doesn’t these days?), you can always send the files via e-mail or iChat. But it’s far more efficient just to give your collaborators shared access to the files, folders, and volumes on your Mac and let them get the files themselves.

Starbucks-AT&T deal could benefit iPhone users

Starbucks’ decision to tap AT&T to provide wireless hotspots at its retail outlets could pave the way for an expanded, potentially free network for users of the iPhone and possibly the iPod touch.

CSSEdit 2.6

CSSEdit 2.6 fits a very particular niche, but one that’s become larger over time. The program provides assistance to those who need to control style sheets directly, without overstepping its role.

If you travel with colleagues for business trips, or if your multiple-Mac family brings its laptops on vacation, getting Internet access for everyone can be an exercise in configuration frustration. There is an alternative: a cellular router.

Avoid file-sharing risks

File sharing helps coordinate group projects, create a central archive of files, and share media. But before you dig into the details of how to share files, consider the risks of file sharing. Glenn Fleishman does just that in this excerpt from his new ebook, Take Control of Sharing Files in Leopard; he also looks at what actions you can take to avoid such risks.

Improving AirPort's range

While Wi-Fi signals are supposed to reach 150 feet in any direction from a gateway, that optimistic number is rarely reached indoors.

Inside Back to My Mac

Back to My Mac, a new feature in Mac OS X 10.5, lets you remotely access other computers you own over a local network or the Internet by gaining access to its shared volumes and controlling its screen. Glenn Fleishman looks at how to get the service up and running and examines some of the security concerns it raises.

Back to My Mac: Apple's Internet mashup

The underpinnings of Back to My Mac are fairly dense, but interesting, as Apple is mashing up a lot of protocols to punch tunnels through Internet architecture that wasn't designed to be tunneled through. Join Glenn Fleishman for a technical tour behind the scenes of Back to My Mac.

Troubleshooting AirPort Interference

Imagine a large room full of loud people. Voices bounce off the walls, making it impossible to follow any one conversation. That’s something like what happens to wireless networks: there are all sorts of other electronic devices out there using the same wireless spectrum, and your AirPort hardware can have a hard time distinguishing one transmitter from another.
