A diminishing few of us can still remember a time when you had to talk on a phone
whose handset was tethered to the phone itself with a six foot cord. Forget about pacing
around the house, let alone having a conversation while gardening in the backyard. It’s
almost just as quaint now to think of a time when we had to sit in front of a PC plunked
onto (or under) a desk in some awkward corner of our house. Ah, the nineties.

Thanks both to cheap laptop PC’s and wireless networking, watching YouTube videos in
the bathroom is easier than ever. You probably already do this if you have a wireless
router, or else you want to do this and so you’ll need a wireless router. Or perhaps you
have an old or underperforming router and simply want to upgrade. Whether you’re looking
for better range, faster speed, or tighter security, these are a few things to know when
going shopping for a wireless router.

Why a wireless router

There was a time when routers were niche equipment used only by network
administrators. But broadband Internet-your cable, DSL, or other high-speed connection
has brought networking into the home. In your home you use a router for three

1.To share your Internet connection with more than one PC. (We’ll use the term
“PC” here for all personal computers, including Macs.)

2.To protect your PCs from hackers trying to gain unauthorized access through your
Internet connect-in other words, as a firewall.

3.To share files between your home PCs-in words, a home network or in technical
terms, a “local area network” (LAN).

A wired router can do all three of these things, but every PC would need to be plugged
into the router with an Ethernet cable. This can get tricky and complicated if your PCs
are far apart or on different floors of your house.

A wireless router cuts the cord, giving you much more flexibility. For desktop PCs,
you may opt for a wireless connection so they can be located somewhere where you don’t
want to run a cable. For laptop PCs and other mobile Wi-Fi devices (like the iPhone), a
wireless router lets you roam around the house without losing your connection. Most
wireless routers also have wired connections, so you can mix and match.

Alphabet soup-b, g, and n

Since their introduction around the year 2000, residential wireless routers have
evolved through three generations. These are commonly referred to as “b,” “g,” and the
newest, “n” (technically, these refer to wireless communication standards known as
802.11b, 802.11g, and
-an earlier 802.11a standard was very slow and not often seen in home

When looking at a wireless router, the first thing you want to check is whether it is
b, g, or n, because they differ in important ways:

b-First generation provides the slowest speeds (maximum 11Mbps) with the shortest
range, and weakest

g-Second generation provides good speed faster than most Internet connections (maximum
54Mbps) with good range, though can vary widely depending on equipment and

n-Third and newest generation provides theoretical speed up to 300Mbps (but will be
closer to 100Mbps under most conditions) with range designed to work best in obstructed

Beware of wireless routers that support only b-these will be old, not to mention slow.
If you already own a b router, this would be a good time to upgrade. You won’t see many
b-routers among new models, but they do show up on eBay and other second-hand
outlets-avoid these.

Today, your best bet is a wireless g router. (These will be backwards compatible with
b, so they will often be advertised as b/g.) The g standard is well-supported and prices
can be very reasonable-expect to find a perfectly good wireless g router for under

Wireless n routers are relatively new to the market-in fact, the standard will not
even become official until this
. But manufacturers have been selling n-based routers for a couple of years
now based on earlier versions of the spec. Truthfully, wireless n promises a lot, but so
far its promise has yet to be realized reliably and affordably enough for basic home
networking. Resist the marketing. For now, wireless n routers are still best left to
customers with more advanced networking experience and a willingness to debug issues with
network stability (or customers with extremely fast broadband-see below).

A note about speedDlinkWirelessRouter.jpg

Like with most computer products, manufacturers advertise wireless routers with an
emphasis on speed. After all, more speed is better, right? Well, maybe.

Most broadband customers in the U.S.-and even many other countries-currently have
Internet speeds under 10Mbps. In other words, a router promising much faster speeds is
not going to make your Web surfing or movie downloads any faster. The router can’t go
faster than your broadband. For (super lucky) broadband customers with speeds above
30Mbps, you may benefit from enhanced wireless g routers (more on that in a moment) or
wireless n, which has adequate overhead to share a connection this fast.

A faster wireless router can increase the speed of your local network, meaning sharing
data between your own PCs will benefit-if this is something you do, such as streaming
music or video from one device to another inside your home.

A note about clients

It takes two to tango, and wireless networking is no exception. Your wireless router
“talks” to the wireless adapter in your PC or other device. The two can only communicate
as fast as the slowest partner.

If you buy a wireless g router but only have wireless b adapters in your PCs or
laptops, then the router will only work at b speeds (and with b security). You probably
should still buy that wireless g router, because you can upgrade your PCs or, eventually,
replace them.

You may see some wireless g routers advertising enhanced speeds-usually with names
like “Turbo” or “Plus” or “108Mbps” or “MIMO“.
Indeed, these wireless routers can provide local network speed as much as twice the
official specification, but only when connected to clients supporting the same
. Often this means wireless adapters from the same manufacturer.

Normally you can mix and match manufacturers as long as you keep in mind b, g, and n,
but these proprietary enhancements break that model-so if you really want “Turbo G,” for
example, be sure you buy Turbo G adapters for your PCs or laptops.

A note about antennas

When looking at wireless routers you’ll notice a variety of antenna
configurations-some appear to have none, or anywhere from one to four. Are more antennas

Actually, all wireless routers have at least two antennas. In some models, one or both
of these might be inside the case, which is why it looks like there are none or just one
externally. Theoretically external antennas allow you some flexibility to tweak their
position-in practice, most people find that tweaking the antennas is not all that
helpful, and can often result in worse signal.

Routers with three or four antennas are using technology called “MIMO” to improve
their range. This technology is designed to work best in environments with a lot of
obstacles-if you need to cover a house that includes steel or concrete walls and floors,
or many smaller rooms rather than larger open spaces-then you may find these wireless
routers more effective.

Extra features

Some wireless routers include extra features that go beyond basic router
functionality. You may find some of these helpful, but others may just add to the price
without adding anything all that useful to you. Let’s consider some of the more common
extras you may see advertised:

  • Print server-A wireless router with a print server will let you connect a printer
    so that a USB printer can be accessed/shared across the network. Not needed for
    printers with built-in networking support. Usually only supports certain printer makes
    and models, so be sure to check the router’s compatibility list before buying.
  • Gigabit networking-Can provide up to 1000Mbps speed for wired PCs plugged
    into the router. All connected PCs must have gigabit Ethernet jacks, and the increased
    speed will only benefit file sharing between these wired PCs. Does not benefit wireless
  • Gaming-Built-in software will detect and prioritize network traffic from popular
    games, so that they are not slowed down by other network activity, like someone else
    surfing the Web. Can be useful for heavy gamers who need the fastest possible response
  • Media-Can stream media hosted on a PC to a media adapter connected to a TV or
    stereo. Usually require a compatible media adapter so be sure to check protocol (UPnP
    is common) between your media adapter and the router.
  • USB-Lets you plug a storage device like a thumb drive or portable hard drive into
    the router, making it available to share across your home network. Easy way to give all
    PCs read and write access to portable storage.
  • High power/gain-Usually includes either a more sensitive antenna or built-in
    amplifier to increase the broadcast range of the router. Wireless range is a
    complicated subject and more power does not always produce better results, but for
    longer distances in relatively noise-free environments this feature can be

So many choices

The major wireless router manufacturers are Linksys/Cisco, D-Link,
and Netgear. You will see these brands dominate in
most retail stores. Look for sales because these manufacturers often discount models from
week to week and you can sometimes find a good deal for substantially less than $50.

Online, you will also see brands, such as Asus, Belkin,
Buffalo Technology, and
all worthy of consideration. If any of the enhanced features listed above are important
to you, start by searching major vendors, including Best Buy, Amazon, or
NewEgg for models that offer these. Otherwise, set a
budget ($50 is a good number) and look for routers below that price to create a
