Hello Mohamed,
1 - Have you been able to onboard the AP into XIQ Connect?
2 - Have you reset the AP back to factory default (reset button down 10 secs)
3 - Is the AP pulling an IP address?
4 - Can you ping and SSH into it?
5 - If you can SSH into it follow this article for some troubleshooting tips: https://extremeportal.force.com/ExtrArticleDetail?an=000057794
I hope this helps,
