How Do I Optimize My Wireless LAN (WLAN)?
Optimal Wireless Technology

There are four main wireless technology standards used today, each of which offers varying maximum speeds, signal strengths (in terms of maximum distance), potential for interference, and of course, cost. Of the standards, the most recent, 802.11n, offers the greatest potential speed and maximum distance, but also one of the highest costs. If your budget supports it, ensuring all of your wireless routers, access points and network adapters are 802.11n-compliant will provide the best possible performance for your WLAN.
Additionally, you'll often benefit from better performance when using routers and network adapters that are from the same vendor. While this isn't always feasible with larger wireless networks, if you can transition your wireless equipment to 802.11n-capable devices from the same vendor, you'll improve your chances for optimal WLAN performance.
