This adds config options to define MACSs of neighbors to be on top of each band's neighbor list. This is important, because some clients will limit the number of entries they use. iOS devices, for exmample, use only the top 6 APs. The neighbors_11g and neighbors_11a take a list or space-separated string of AP BSSIDs to keep at the top of each band's neighbor report. The list is used when the neighbor report is being assembled. Any listed AP that is not online will not be included in that report. When the next report is assembled, if the AP is back online, then they are restored to the indicated order. There's only one list for each band. In case of multiple SSIDs, you can include BSSIDs for all of them, and they will be filtered by SSID when assembling the reports.

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. |

| 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. |

ubus interface
To get an overview of all connected Clients sorted by the SSID.
root@OpenWrt:~# ubus call dawn get_network
