Air-AP3802I-B-K9 || users are unable to access internet when connected

[ceciliok]

Hello Engineers,

i have a cisco wireless access point Air-AP3802I-B-K9. When users connect to they don't get internet 

The following steps have been taken:

Initially, the port on the switch changed and monitored yet the issue persisted, with the AP's IP address exhibiting intermittent Reachability Timeouts (RTOs).

Subsequently, two new cables were substituted in an attempt to rectify the issue. However, despite the cable replacement, the problem persisted, with RTOs persisting intermittently over time.

Further troubleshooting involved swapping the problematic AP with another operational AP port. the issue persisted with the originally problematic AP, while the replacement AP operated seamlessly on the same switch port.

Please help

 - As far as Internet access is concerned ;  check if the client is getting an IP address . Internet access is not related to AP or cable problems , of course the AP should have normal network connectivity too (the AP  itself should be free from any networking issues)
             If the problem is on a single AP only you may also try rebooting it (e.g.)

I think you've diagnosed the problem for yourself - faulty AP?

Have you checked for crash files and checked the logs on that AP?

What model WLC are you using and what version of software is it running?
