I had a similar problem and it turned out that one of my dumb (unmanaged) switches did not support VLAN pass-through. It was a TP Link 2.5G switch. When I changed it with a Netgear, all the VLAN's started working. It took me a while to figure it out, but some dumb switched (even new ones) do not support VLAN pass-through.…

Thanks David. I use Nebula and found it as well in the AP and Port settings. Good to know where I can change it as well if I decide not to renew Nebula. I assume you have to change it for every AP when web managed? I wish there was a way in Nebula to apply it only to one AP, it changes all of them. George

I solved this. There was a Trendnet switch between the AP and the MG-108. The MG-108 actually supports passing through the VLAN tag (apparently the Trendnet does not). I connected the AP directly to the MG-108 and all the SSID are working on all the AP's. This work much better than expected. George

Well, I kind of solved my own problem. The MG-108 does support vlan passthrough, that's all I needed. I had a Trendnet switch between my AP and it. I guess the Trendnet does not support vlan passthrough. I removed it from the path and now the vlan's are making it to my router/firewall. No need for a managed switch. George

I need something with at least six to eight 2.5gb (I could do 10gb as well) ports. I don't need a SFP port. I don't see anything with those specs from Zyxel.

The only difference between the problem AP and the good ones is that the problem AP is connected to a Zyxel MG-108 switch. Does that switch support VLAN's? Thanks, George

It's the Zyxel Office AP that's experiencing the issue. My organization is George993 and my site is Home. Mango and Gary are the problem, Frank works fine. I have several items connecting: Alexa, Macbook Pro, Dell Latitude laptop, a Canon MF printer, iPhone 14Pro, SurfacePro, etc. I can connect to that SSID if I go by…

I believe that's part of the MLO spec. I had to create a second network (SSID) for my old clients with WPA2 security. It works pretty well that way. I actually created a separate vlan for it and just added my IoT devices. George

I experienced this as well. The issue is that when you enable MLO, WPA3 is the only supported security. It does not drop down to WPA2. Hope that makes sense. George

I confirmed it by noticing that all my 2.4 devices lost connection. Then I used a wifi scan app to see what channels were transmitting around me. I could see the 5GHz channels from my AP's but could not see any of them on the 2.4GHz channels. I need to check the 6GHz channels, I used a machine whose adapter does not…

BTW, I just double checked. I'm losing my 2.4 radio when I turn on MLO, 5 and 6 are still sending a signal. George

Once I turn MLO on in Nebula, I no longer see any wifi signal from any of the AP's. Can clients that do not support MLO connect to the AP's? Thanks, George

Thank you. I just didn't know where to look. George
