Sorry I'm no expert, hope informations provided are enough :   We have several PDA, several AP and several SSID. I tried to install a PDA after a problem with an APP, so I reset the device, connect to SSID of another city and...no connexion (temporarily full?) When trying connection to here (let's name is A) no error. When trying to connect to the other city (SSID B), it failed.   Try with another PDA and same error. Seems the DHCP failed (picture can't be included, link at the end). So I try using static IP, same error. Tried to reboot the AP, same error. Other PDA on B city are connected to B SSID without issue. Here on A AP or my A-IT no issue. Really just on B SSID when on A.   I extract log when trying to connect but only can see the same 3 requests again and again.   Can't insert files or here the link : DHCP error : https://www.dropbox.com/scl/fi/cih0sxh276wg52lnhqd3x/Capture.JPG?rlkey=ygqk07e757o3aeaccntajbebc&st=2kdaoywx&dl=0 PCAP file : https://www.dropbox.com/scl/fi/2kunzpvs7om62ilxhlvi4/CERP_wifi_MR-CERP-Informatique_IF-Wireless.pcap?rlkey=h8kwmcs1a2if5xysa2my4q4pt&st=bk8wzq9u&dl=0  Connection log : https://www.dropbox.com/scl/fi/g6o7x0punlt343j4jpvu7/capture2.jpg?rlkey=te8eewxzxeay39g5745p26zxe&st=xotxeln6&dl=0 ...
