Tech Tips

Unshackle Your Wi-Fi


If your home Wi-Fi network sometimes seems to drag at a snails pace, check if all the PCs on your network have the same speed wireless cards (Wi-Fi or 802.11 comes in three main speeds: in order of slower to faster, b, g and n). It turns out that Wi-Fi routers run only as fast as the slowest device on the network. So even if you have a new "n" router, a new desktop PC with a speedy 802.11n wireless card, and an old laptop with an 802.11b card, the router will only transfer data at the "b" speeds when both are connected at the same time. So if any of your machines are stuck with old 802.11b cards, the only option is to upgrade them with new internal or USB wireless cards, or to make sure to turn off your slower devices when you feel the need for speed.

Apple Updates AirPort Express With Faster Speeds

Apple's AirPort Express Goes to N

Apple's AirPort Express has been hailed as a user-friendly, portable, out-of-the-box solution for wireless networking. It lets you connect your computers, share a printer, and stream your music over the air with little more setup required than plugging the pocket-sized thing in. Now the device has gotten even better, taking a step up to the faster, 802.11n standard.

The former AirPort Express used the 802.11g standard, which delivered a maximum speed of 54 megabits-per-second over the 2.4-gigaherz wireless band, the same many wireless phones use. 802.11n uses both the 2.4 gigaherz band as well as the 5-gigaherz bands, providing maximum broadcast speeds of 248 megabits-per-second, nearly five times that of g. Additionally it offers nearly twice the range, up to 820 feet, for those with really big pads.

The new AirPort Express is available now at the Apple Store for $99.

Just Tell Me What to Get: Home Network

Apple Airport Extreme Base Station
A reader writes: My wife just got a new laptop through work, which means we now have two computers in the house. I want to set up a wireless network so we can split our cable Internet connection, but I don't want any hassle. The last time I set one up was a few years ago, and I remember it being a total headache. What's your advice for getting a Wi-Fi network up and running quickly and painlessly?

Hey reader: This one is a no brainer -- go with the new Apple Airport Extreme Base Station. Apple is religious when it comes making its products easy to use, and that piousness most definitely extends to its wireless networking router.

Available for both Mac and PC, the Base Station is a snap to set up. You simply plug it in and connect it to your cable modem with a network cable. Then, insert the install disc into your computer and follow the simple instructions, which take you though stuff like naming your network, naming your base station and setting up encryption. Unlike a lot of routers out there, the super-secure WPA2 encryption is activated by default. That's it: You've got a secure wireless network up and running.

But easy set-up isn't all the Airport Extreme Base Station has going for it. Apple has equipped the unit with 802.11n wireless technology, which is up to five times faster and boasts twice the range of previous wireless standards. Don't worry if your computer's Wi-Fi chip isn't 802.11n, you'll still be able to use the Airport Extreme Base Station -- just not at top speed.

Wait, there's more! The coolest feature is the built-in USB 2.0 port. Plug in a printer and now both computers can use it. Or, connect an external hard drive so you and the missus can share files.

We've dealt with our fair share of complicated network set-ups in the past, and take our word for it: Nothing comes even close to being as blissfully easy to use as the Airport Extreme.
