10 tips to help improve your wireless network (Update)

8. Update your firmware or your network adapter driver

Router manufacturers regularly make free improvements to their routers. Sometimes, these improvements increase performance. To get the latest firmware updates for your router, visit your router manufacturer's website.

Similarly, network adapter vendors occasionally update the software that Windows uses to communicate with your network adapter, known as the driver. These updates typically improve performance and reliability.

9. Pick equipment from a single vendor           

Although a Linksys router will work with a D-Link network adapter, you often get better performance if you pick a router and network adapter from the same vendor. Some vendors offer a performance boost of up to twice the performance when you choose their hardware (like their USB wireless network adapters). Linksys has the SpeedBooster technology for its wireless-G devices, and D-Link has the 108G enhancement for its wireless-G devices. These enhancements can be helpful if you have wireless-G devices and you need to transmit over a long distance or you live in an older house (old walls tend to block the signal more than newly built ones do).

If speeding up your connection is important to you, consider the next tip—upgrading your wireless technology.

10. Upgrade 802.11a, 802.11b, and 802.11g devices to 802.11n

Although wireless-G (802.11g) may be the most common type of wireless network, wireless-N (802.11n) is at least twice as fast and it has better range and stability. Wireless-N is backward-compatible with 802.11a, 802.11b, and 802.11g, so you can still use any existing wireless equipment that you have—though you won’t see much improvement in performance until you upgrade your computer or network adapter to wireless-G, too.

If you're using wireless-B or wireless-G and you're unhappy with your network’s speed and performance, consider replacing your router and network adapters with wireless-N equipment. If you're buying new equipment, definitely choose wireless-N. Linksys Wireless-N routers, for example, are powerful, secure, and simple to set up. So are Linksys Wireless-N USB wireless network adapters.

Wireless networks never reach the theoretical bandwidth limits. Wireless-B networks typically get 2–5 megabits per second (Mbps). Wireless-G networks are usually in the 13–23 Mbps range. The average everyday speed for wireless-N equipment is about 50 Mbps.
