Hi all

I have an ISP router/modem device that is compeletly bare bones and offers almost no configurability (so not VLAN aware) will the VLAN I setup on my Layer 2+ Switch not work?
 

The issue I am facing is when I setup a VLAN via the controller will the following details in the screenshot below:

I then assign this VLAN ID to my WLAN:

The VLAN interface is enabled on the switch and all the switch port profiles are set to ALL. When I connect to the "IOT_Devices" network I have no internet connection.

Is there some configuration I am potentially missing ? Or is just due to my ISP router not being VLAN aware? I was under the impression that I could still setup VLANs with an L2+ managed switched I just wouldn't be able to have inter-VLAN communication without a router.

On a side note you might be wondering why I don't replace the ISP router, unfortunately I am with Virigin Media and they don't allow this. Also you might be wondering why I don't just put their useless router into bridge mode well I got their new 5x modem and it currently does not have this feature enabled yet. I also don't have the knowledge to attach a second router to the ISP router and mitigate double NAT issues.
