How to speed up your PC: 24 performance tweaks

Hardware upgrades, software tweaks and networking tricks to get more PC speed

Networking speed boosts

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 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 router, you must use WPA2 encryption; the older WPA encryption operates at half the maximum theoretical speed that 802.11n offers.

Tinker with the antennae. By far the easiest way to alter your network's performance is by moving the antennae 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.

Move your router. 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 an ADSL 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 PCs 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.

Check for interlopers. Network performance suffers when numerous devices use the pipe simultaneously. You can monitor your own internet usage, but what if you aren't the only person using your connection? Check for interlopers freeloading on your network via the DHCP client list for your router.

Such lists identify everything connected to the network, including MAC addresses and computer host names. Wireless printers, networked home-entertainment 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 password and encryption key.

Get your traffic in shape. If you're up for some advanced network tweaking, consider traffic prioritisation for your router. Traffic prioritisation (aka traffic shaping) is a technology that enables you to tell your network to let one form of traffic have precedence over another. For example, you may want to give voice and video the highest priority, so your video calls go through with no lag and stutter, while giving email and file downloads lower priority because they are less sensitive to delivery delays.

These days, more and more routers are adding Quality of Service (QoS) features. Look for router models designed for gaming use or for 'experts', such as D-Link's DIR-655, and then venture into the QoS settings in the product's configuration menus. Expert users may also consider downloading third-party firmware for popular routers to add QoS feature support to their network routers.
