Wi-Fi tweaks for speed freaks

How to get the most speed and reach out of your wireless network.

One thing you can depend on these days is that the claims made for wireless routers, like 300Mbit/sec. throughput and 1,000-foot range, are nothing more than digital pipe dreams. The plain and simple truth is that these speeds and distances just aren't going to happen in your home, office or any place on this planet.

If you're disappointed by the speed and reach of your wireless network -- and who isn't? -- there's a lot you can do to grab every last bit of data and foot of range. I spent a few hours optimizing my network and more than doubled its indoor range from 90 to over 200 feet (with an additional 150-foot extension into my backyard) while increasing performance fifteenfold -- all with a two-year-old 802.11g router.

Some of the techniques I used are basic, like where and how to set up the router. Others are more involved and require special equipment, but they can make a world of difference. Plus, for those who don't know what to do when the data connection goes south, I've also included a troubleshooting checklist that can help get your network back into the fast lane.

The beauty of modern Wi-Fi equipment is that it all works together, so you can build a network with best-of-breed gear. For instance, my network has a router from one maker, antennas from another, a print server from a third and client radios from several different companies. Think of it as the UN of wireless: the world cooperates to make your online life a little easier.

Setup: Location, location, location

Where you put the router and how it's set up are two of the most important -- and often ignored -- aspects of creating an efficient wireless network. Most people put the router in the first place that comes to mind. Big mistake.

Think of the router as the center of a sphere of connectivity that extends out in all directions from its antennas. My advice is to put the router as close as possible to the physical middle of the home or small office it needs to cover. Start with a building floor plan or rough drawing, and draw diagonal lines from the corners to mark the center.

Of course, some people -- including me -- can't follow that advice. Perhaps you have a stone wall or a brick chimney in the middle of the building, or, as in my case, the cable line enters the building in the worst place possible. If for these or other reasons you can't put the antenna in the ideal center location, don't despair; I have solutions for you later.

Now, look around and find a good home for the router. Avoid corners (particularly in older buildings), which diminish the signal as it passes through, and don't put the router in a closet. A great place to stash a router unobtrusively is in a bookcase or an entertainment center.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.
