Unable to Discover AP AC lite

I've been reading everywhere on the site that i can think of and cant find a solution. My AP is connected by POE out on my ER-X and was seen and working before it went into isolated mode (been working on my vlans). So i couldnt get it out of isolated mode no matter what settings i changed on the unifi controller. Now at this point I decide to do a factory reset on the AP. All good, solid white light on the AP. but the unifi controller cant find the AP, I also can't find it with the AP just to troubleshoot. Any idea's what I need to do?

@AmazedMender16 & @techsolsc thanks for your help. I removed the AP from the ER-X and placed it on an injector and the controller found it no problem. not sure why this mattered, but its fixed now. thank you again for chiming in!

Re: Unable to Discover AP AC lite

You prob have a VLAN issue.

Scan the network with Angry IP scanner.  Do you see the AP's MAC listed?  If you don't see the MAC with an IP then....  yes prob have a VLAN issue.

Re: Unable to Discover AP AC lite

Hello @dwlyles,

 

Does the UAP grab a DHCP address?

How did you configure the VLANs?

Re: Unable to Discover AP AC lite

So my Vlans are on eth1 and I assigned the Vlans on the unifi controller and assigned networks to the APs. Always choosing "ALL" profiles.

Re: Unable to Discover AP AC lite

I'm more confused why my factory reset AP cant be seen, neither by controller or by app.

Re: Unable to Discover AP AC lite

I'm still courious if you scan the network do you see the AP listed, along with your controller and PC's?

 

Have you used :

https://chrome.google.com/webstore/detail/ubiquiti-device-discovery/hmpigflbjeapnknladcfphgkemopofig...

to look for the AP?

Re: Unable to Discover AP AC lite

Hello @dwlyles,

 

Are both devices on the same VLAN? 

Is the UAP able to ping the controller?

@AmazedMender16 everything is currently on vlan 1 on my ER-X. I used eth4 as passthrough to the AP. the controller is currently using vlan 1 as well.

Re: Unable to Discover AP AC lite

Hello @dwlyles,

 

Strange... are you sure the UAP was getting powered?

Re: Unable to Discover AP AC lite

@dwlyles If your AP was an UAP-AC-Pro the ER-X will not power it. The Pro requires 48V and the ER-X only support the 24V AC-Lite's and AC-LR's.
That's why it wouldn't work.

Glad you got it to work.
