Cisco access point 1532I some client connected but can't have network access

[lavoiekeven]

We are trying to setup an outdoor wireless network with 1532I access point in autonomous mode. We created a 2.4Ghz network with WPA ver 2 and AES encryption.

The problem is that some devices stay connected but can't access event to network (LAN or WAN). There are some other devices that stay connected without  any problem. There is no warning or error in the event logs.

The initial setup 1532I access point powered by a 2960G POE switch.

In a trying to identify the problem I setuped another access point in my local home powered but a power injector and I got the samew problem: My phone (Samsung S8) showing and icone of network with an exclamation point. My raspberry pi work perfectly and is never disconnected.

Thanks.

Hi

   If one device is working fine, it´s hard to believe the problem is configurarion issue. Exclamation mark usually means the device tried to validate internet access and failed.

 Verify if device has an IP address, if it can ping the gateway. If true, you should be good and the problem can be a bug.

If not, some troubleshooting should be done!

-If I helped you somehow, please, rate it as useful.-

I resolve the problem with the gateway there was a probleme the the fibre converter. So I plug the acces point this way:

[Internet] - Modem - Router - 2960G POE+ switch - Access point

It seems, now that the network shutdown down for some second than comeback.

The access point has the lastest firmware15.3(3)JJ. 

I also got cisco 1140 plug with the same setup. It work perfectly.
