All the AP24's are configured as a bridge, so all IP addresses are on the 192.168.0 network.
WDS (wireless distribution system) is also enabled which enables the whole setup to appear as if it is one ethernet switch. I've set wds-ignore-ssid=yes, which as I understand it, allows WDS across different SSIDs. In order for that to work, all access points must be on the same frequency, and dfs-mode (dynamic frequency selection) turned off.
I've chosen frequency=2452 Mhz for testing at FLAB. In the field we can use "interface wireless frequency-monitor" at setup to find a quiet frequency.
Note these settings:
- frequency=2452
- tx-power-mode=default
- dfs-mode=none
- wds-mode=dynamic
- wds-ignore_ssid=yes

AP24-3 at near
The AP24 supports a maximum bandwidth of 54 Mbps, whereas the highest I've seen on an Etherant is 11 Mbps. So the plan is to use the single antenna AP24 at the near tower instead of an Etherant.
