This is mainly a post to remind me how I resolved an issue I was having. I have a rooted android phone w/ wifi tether installed. This will allow you to tether to your phone without paying all the extra charges. This works fine for me, but I wanted to lower my transmit power because I was being picked up as a rogue hotspot. I don't want to get to specific about my issue, just know that if you need to do it, it can be done. Well, if your wifi chip supports it. Anyway, you need to download iwconfig and install in /system/xbin on your phone. You can google on how to write files to /system. If you use ES Explorer, it is pretty simple. Then run this command:
# iwconfig wlan0 txpower X
X being the txpower you want. In my case, I chose 0 which sets my tx power to 1dBm. Your mileage may vary of course. Later.
# iwconfig wlan0 txpower X
X being the txpower you want. In my case, I chose 0 which sets my tx power to 1dBm. Your mileage may vary of course. Later.
