Replacing the standard firmware in certain wireless routers and access points (''e.g.,'' [[wikipedia:WRT54G|Linksys WRT54GL]]) can provide greatly increased functionality (''e.g.'' [[wikipedia:Hotspot (Wi-Fi)|hotspot]] capability) and improved stability, although a fair amount of technical skill may be needed. For specific features and supported products, see:

* The raw speed reported by your wireless network adapter is ''not'' necessarily a reliable indicator of actual raw speed. The reason is that transmit speed fluctuates according to the wireless error rate, and when the wireless link is idle, unrealistic speed may be reported (since no errors are occuring when the wireless link is idle).
