DHCP Server Unreachable after update

[kfarley]

I have 3 AP’s
2 x AP650
1 x AP630
flat L2 network 
i noticed after updating to the latest version 10.1r6 my devices are failing to get IP’s


going into the logs i think i’ve narrowed it down to my 650’s as the cuplrit. the logs show 

DHCP Server Unreachable
 

notice how the cuplrits are only kris’s room and OWEN
it’s also evident by the devices themselves (my android for example showing it “couldn’t get IP” 

is this a known issues with the AP650’s on the new firmware?

is there a fix at all? 

my DHCP server is hosted by my fortigate 60E firewall. all hardwired devices negotiate IP’s just fine, it’s only an issue with my wireless.

I would recommend going to 10.0r8a instead of 10.1r6, based off the information in this article: https://extremeportal.force.com/ExtrArticleDetail?n=000050608&q=10.1r6
