VLAN DHCP issue on Ubiquity AP
Hi,
I have a multi-brand setup in my office that includes a TP-Link TL-ER605 (HW v2.0) router with the latest firmware, a Cisco SG350 24P PoE switch, and a Ubiquiti U6 LR access point.
I created a new VLAN with the IP address 192.168.30.1 and VLAN ID 30, and I enabled the DHCP server for the range 192.168.30.100 to 192.168.30.200. When I connect my laptop, set the VLAN ID to 30, and configure the network for DHCP, the router assigns an IP address from the DHCP address pool correctly. However, it is not providing a VLAN IP for the Wi-Fi SSID.
I have configured VLAN 30 as a third-party gateway in the UniFi Controller and assigned this VLAN to the SSID "test_vlan." Despite this configuration, the router does not give out DHCP addresses for this SSID. I also attempted to set a static IP for the wireless device, but it still does not connect.
I haven't created any ACL rules, and I am not using the Omada Controller; I am using the web GUI to configure the TP-Link router. Can you help me understand why the router is not providing a VLAN IP to the Wi-Fi SSID?
Thank you!

Actually connection from router is going to vlan aware unmanaged cisco switch sg94-24t. And only port 4 is using. Connection between router and switch is port 4.port 5 and port 3 are free. No network cable connected to port 5 to switch. Should i connect all ports to switch?
What should i do ?
ok, if you have an unmanaged switch, it could be the problem, not everyone gets through tagged packets. I don't know about this, then you probably have to go to the cisco forum to get more info
I don't know what to do now, I would probably try to switch to managed switches

how do you test from the laptop? Do you plug the laptop into the wall and set vlan on the network card?

Yes, i set vlan id 30 on network card settings and then set ip address as automatically. Then router will assign vlan ip.

yes it sounds strange, when you connect the access points to the switch they get ip from vlan1 or vlan30

Vlan 1 which is untagged. Default ip is vlan 1 which has no issues in connecting. Issue only happens when i try to use vlan ip on SSID.

it sounds strange, I have worked with Cisco for many years, but mostly firewalls but the managed switches must be configured with vlan otherwise they will not work with vlan. it is maybe possible that unmanaged switches forward vlans but not managed ones, if you google Cisco SG350 you will find the manual on cisco
