Why my wireless guest VLAN cannot get the IP?

[Deleted User]

When configuring the guest VLAN, it is also necessary to configure L2 isolation. Typically, the gateway's MAC address should be added to the whitelist. If the issue is that the end client fails to obtain a VLAN IP address, please access the gateway and use the CLI commandshow interface VLANxxx.

This will display the VLAN interface's MAC address, as shown in the following screenshot.
