  • 1.  What is the effect of changing the VLAN assigned in an SSID?

    Posted 07-24-2024 14:17

    I want to edit the VLAN in an SSID for IoT devices and make sure doing this will not impact the devices using it negatively.  I am concerned that they would have to be restarted to send out a new DHCP request and get the new IP in the new range.   If I do not, I suspect they would have an old IP but be on the "wrong VLAN" and not work until they decided to request a new IP.

    Hi John,

    Changing the Vlan would affect the IP connectivity and would need a new DHCP lease in the new subnet. To go around this problem, you can force all client to reconnect. This will disconnect all client on the IoT SSID. All client would then go though the normal process of Auth, DHCP request, ARP etc.

    To force reconnect all client, you can go under WiFi Clients and filter with the SSID you want, then select all client and press the top right button "reconnect.

    Regards,

    Francis,

    That's a good idea.  The devices we have on this SSID are very simple air quality sensors. I'll test one to see if it does reconnect.
