We have a Zone Director model 1200 version 9.12 build 336 and 9 AP's. In the last couple of weeks the ZD will just stop handing out IP's to clients. The signal is still strong but it will either take a long time to get and IP or it wont issue one at all. If we reboot the AP's then it will start working again. It is set to hand out 100 IP's and we do not have anywhere near that demand. We also recently added two new outdoor AP's to the system and one of them seems to be the biggest offender. Thank you
