 Enabling Afterburner turns on support for Broadcom's frame-bursting and compression technology to improve 802.11g wireless throughput. This feature is also known as //125 High Speed Mode// (or //125HSM//) and goes by other names with other hardware vendors. Theoretically, this boosts signalling rates to 125 MB/s. Realistically, one can expect 30-40 Mb/s throughput in real world environments. Since this is a proprietary protocol extension, effectiveness will vary depending on the client device maker as well. Enabling Afterburner turns on support for Broadcom's frame-bursting and compression technology to improve 802.11g wireless throughput.

 Turbo QAM, or 256-QAM is a modulation method in which the two carrier signals are shifted in phase by 90 degrees. These two signals are then modulated and combined. The 90° difference in phase between the two signals means they are "in quadrature". Turbo QAM, or 256-QAM is a modulation method in which the two carrier signals are shifted in phase by 90 degrees.

-In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates. In reality, most claims of big increases in transfer rates are likely exaggerated. QAM links are more susceptible to noise. As a result, Turbo QAM is generally only useful in very low-noise/interference wireless environments. Many people report it being effective on line-of-sight links of up to about 25 feet. Vendors claim the range with Turbo QAM may improve when beamforming is used. You may need to experiment to see what works best on your network. \\+In theory, this modulation method makes it possible to transmit more bits per symbol, and thus increase data rates.
