Hello. I want to share with all of you my findings about the "power" potential of Buffalo AirStation WHR-HP-G54. The default transmit power setting on Tomato is 10mW. After some research on Buffalo AirStation WHR-HP-G54, I established that it's end step of amplifying circuit is an Anadigics AWL6153. Anadigics AWL6153 have an output power levels of 25 dBm for 802.11g witch is approximately 316 mW, and 28 dBm for 802.11b witch is approximately 630 mW. This output can be achieved by suppling Anadigics AWL6153 with 5.0V. Anadigics AWL6153 can run on 3.3V, witch will provide 21 dBm for 802.11g witch is approximately 130 mW, and 25 dBm for 802.11b witch is approximately 316 mW. I really don't know what is the default voltage of Anadigics AWL6153, but there are some mods on the internet for increasing chips voltage from 3.3V to 5.0V. I've tested changing the power settings my Buffalo AirStation WHR-HP-G54. Used Hardware: 1. Buffalo AirStation WHR-HP-G54 2. Dell Latitude 120L (IntelÂ® PRO/Wireless 2200BG miniPCI card) 3. Custom made Asus P5WDG2 WS Pro PC. Used Software: 1. Real-Time Bandwidth monitor of Tomato v1.07 2. NetStumblerÂ® v0.4.0 (Build 554) 3. DC++ v0.674 on my ISP's local hub. 4. A 538 MB avi file. Terrain definition: Wall - 20 cm (7.9 inches) of concrete with structure steel inside. Point 1 - 40 cm (1.31 ft) from the router. Clear sight of vision. Point 2 - 4 m (13.12 ft) from the route. Signal going trough one Wall. Point 3 - 12 m (39.37 ft) from the router. Signal going trough two Walls. Power settings: 1. 10 mW Tomato's default setting. 2. 130 mW Anadigics AWL6153's maximum power on 3.3V. 3. 251 mW Tomato's maximum setting. And here are the results summarized in exel. First - Noise Floor chart. Closer to -100 the better. Second - Signal Strength chart. Closer to 0 the better. Third - Speed comparison carts. The higher, the better. PEAK value is the highest value achieved during the test. The average value is more important. 10 mW Chart. 130 mW Chart. 251 mW Chart. Question number one: If Buffalo's default voltage of the Anadigics AWL6153 chip is 3.3V, what will happen when I set Tomato to a higher value then 130mW? Answer: Nothing. The router will work with no problems. Even when going to 251 mW the router performs as intended from manufacture. No jamming, needs of reset or any other unusual stuff. Question number two: Is there any change in performance after going to 251 mW? Answer: It depends on your terrain and the frequency load around your location. You can see that after increasing the power output to 251 mW, there is a significant increase in signal strength. I really can't do the test in a frequency quiet environment, so you make your own conclusions from the charts. There is no way to set Tomato to value higher then 251 mW. Question number three: Is there a temperature change after setting 251 mW power output? Answer: No. The router's casing has exactly the same temperature on 10 mW and 251 mW. I've not opened my router to measure the exact temperature. I've set my router to 251 mW since June 2007. Exactly the first day i bought it. And i have not experienced any problems with it.
