How to speed up your network

4 ways to speed up everything attached to your network

Not all varieties of slowness are created equal. If computer-to-computer file transfers or web page loads are bugging you, consider focusing on your wireless network configuration instead of mucking about in Windows or inside your computer case. Here are some common ways to give your computer a boost by scrutinising the network side of the equation.

Upgrade everything to 802.11n

Upgrading to a newer router will help - but only if all of the equipment on your network supports it. A new router plus an old laptop won't increase your performance much, unless you're on the outskirts of the wireless connectivity zone, in which case you may achieve better performance simply because the new router's signal is stronger. If you want to obtain the best throughput from an 802.11n class router, you must use WPA2 encryption (or no encryption at all): The older WPA encryption operates at half the maximum theoretical speed that 802.11n offers.

Tinker with the antennas

By far the easiest way to alter your network's performance is by moving the antennas on your router, if it has visible ones. Try different configurations - all straight up, bent to 45 degrees, aiming to the side, or combinations of the above. Depending on your router, antenna tweaks can give you a boost of up to 20 percent on network throughput.

You might move your router, too. Many users seem to think that once a router is installed, it needs to stay put. Not so: A cable modem can connect to any functioning cable outlet, and a DSL modem can connect to any phone line. The rule of thumb is to position the modem (and router) as close as possible to the location where computers will be used most frequently. If you have computers set up throughout your house, try to place your network equipment as centrally as you can. In too many installations, the modem and router are locked in the basement, where distance and interference combine to slow the network down.

Check for interlopers

Network performance suffers when numerous devices use the pipe simultaneously. You can monitor your own Internet usage, of course, but what if you aren't the only person using your connection? To determine whether interlopers are freeloading on your network, consult the DHCP client list in your router's configuration tool. Most such lists identify everything connected to the network, including MAC addresses and computer host names. Don't be alarmed if you see more devices than just your laptops and desktops: Wireless printers, networked home-theatre equipment, media servers, smartphones, and other wireless gadgets may appear in the list. But if you find something that shouldn't be there, consider upgrading to a higher level of Wi-Fi security, and change your administrator password and encryption key.
