This renames "mode" to "rrm_mode", and its type from int to string. This way, we can set the correct mode for a probe request from the STA reported capabilities, along with the preferred order of modes, set by the "rrm_mode" uci config. rrm_mode is a string of possible mode letters: 'p' = passive report 'a' = active report 'b' or 't' = beacon table report. Setting rrm_mode='pat', will try to send passive reports, if available; if not, it will try an active report, using a beacon table if all else fails. If you don't include a letter, the corresponding report type will be disabled. An empty string will disable beacon reports. Unrecognized letters are ignored, as well as repeated modes. If the configuration is not present, a default value of 'pat' will be used. Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com> |

DAWN
Decentralized WiFi Controller
Installation
You need full wpad installation and not wpad-basic.
See installation.
LuCI App
There is an luci app called luci-app-dawn.
Setting up Routers
You can find a good guide to configure your router is here. I setup the OpenWRT Router as dumb APs.
Configuration
| Option | Standard | Meaning |
|---|---|---|
| ht_support | '10' | If AP and station support high throughput. |
| vht_support | '100' | If AP and station support very high throughput. |
| no_ht_support | '0' | If AP and station not supporting high throughput. |
| no_vht_support | '0' | If AP and station not supporting very high throughput. |
| rssi | '10' | If RSSI is greater equal rssi_val. |
| low_rssi | '-500' | If RSSI is less than low_rssi_val. |
| freq | '100' | If connection is 5Ghz. |
| chan_util | '0' | If channel utilization is lower chan_util_val. |
| max_chan_util | '-500' | If channel utilization is greater max_chan_util_val. |
| rssi_val | '-60' | Threshold for an good RSSI. |
| low_rssi_val | '-80' | Threshold for an bad RSSI. |
| chan_util_val | '140' | Threshold for an good channel utilization. |
| max_chan_util_val | '170' | Threshold for a bad channel utilization. |
| min_probe_count | '2' | Minimum number of probe requests aftrer calculating if AP is best and sending a probe response. |
