I'm updating a sub-project that's based on OpenWrt and am adding support for the TP-Link WBS210 (and possibly the WBS510 if I get the right information). One of the requirements for the project is per channel power levels (for example, if all 14 channels are a max of 30dBm, we put 14 => '30' in the code). I'm waiting on my device to arrive for testing but thought that since it's in OpenWrt, someone may have the information already.
For our project, the instructions for determining the max power per channel are to set the power on the first channel to 30 in basic setup and apply the changes. Then use "iw dev wlan0 info" to see what the max power accepted was. If necessary, repeat for each channel.
Any information that you can provide on the maximum power levels per channel will help greatly. I'm hoping to have a working firmware when I get the device.
Thanks, and have a great day.
