Ok, then it should work if the switches are configured correctly.

If switch is the issue, wouldn't same issue happens to the laptop too, but how come it is getting vlan ip. I connected laptop to lan port in wall and that lan coming from switch in my floor.

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 ?

  @TOSC 

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

  @TOSC 

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
