- You have two access points, interconnected via 802.11s mesh.
- The mesh is the transport for multiple VLAN networks which are the underlying transport for multiple WiFi SSIDs.
Wired uplink for VLAN 10, 20 === WifiAP-01 === (( 802.11s mesh SSID )) === WifiAP-02 === SSID "10-Intranet", SSID "20-Guest"
If your mesh becomes disconnected, WifiAP-02 will still allow clients to log on to its "dead" SSID and the devices will complain "connected to WiFi, no local/wan connectivity".
This script improves the situation by automatically detecting the mesh outage and disabling the SSID "10-Intranet" and "20-Guest". When the mesh comes up again, the SSID will be re-enabled.
The full script and installations instructions can be retrieved from:
The following script needs to be placed on WifiAP-02:
# Installation: ## opkg update; opkg install bash ## chmod +x "/root/cron-meshctl.sh" ## /etc/crontabs/root ### [ADD LINE] #### */1 * * * * /bin/bash "/root/cron-meshctl.sh" >/dev/null 2>&1
I've verified this working on my Archer C7 v2|5 devices. When AP 1 <=> AP 2 get disconnected e.g. due to maintenance, power-off of AP 1), AP 2 disables sending SSIDs "10, 20" automatically until AP 1 is serving the backhaul for these SSIDs again.
