2 AP stopped working with GS1900-24EP

So you connect a new AP in the same place as the two AP's that don't work and it works?

Correct

That seems odd the switch looks to be working fine.

But then I don't get why the AP's work fine without the switch maybe its something to do with Unifi Cloud Key that the AP can't talk to it?

Indeed, ut's such a wierd problem. The Cloud Key can talk to the AP just fine if I connect another Zyxel switch (GS1005HP).

Router > Technicolor TG799vn v2 / Unifi Cloud Key 2 > Zyxel Switch GS1900 > AP = NOT WORKING

Router > Technicolor TG799vn v2 / Unifi Cloud Key 2 > Zyxel Switch GS1005HP > AP = WORKING

Any ideas?

Hi @SwitchAnon,

Thanks for sharing the topology. Could you share more details like: which switch port connects to AP and which port connects to Technicolor TG799vn v2 / Unifi Cloud Key 2 or router?

And this issue is that the some AP can't communicate with Technicolor TG799vn v2 / Unifi Cloud Key 2? Can the AP wireless client access Internet?
