2504 autoinstall fails with code 126.96.36.199 and 7.5.102
I am running into an autoinstall issue with our 2504 WLCs. Up to code version 7.2 I was able to use autoinstall to prime the WLCs by downloading the config from a TFTP server.
After upgrading to 188.8.131.52 the autoinstall fails because the WLC becomes unreachable after it received a DHCP address, gateway, option 150 and the bootfile. If I configure the controller manually, all is working as intended. Before upgrading to code version 7.4, we installed the FUS update 1.8 as described in the release notes.
The DHCP parameters are correctly handed out and I see the IP in the DHCP bindings with the management interface MAC. The WLC accepted all the parameters and in the console output the autoinstall is attempted as intended.
Pinging the DHCP - IP of the WLC is unsuccessful and thus the WLC cannot reach the TFTP server. A ping to a local broadcast shows 2 other clients (APs) on this segement but not the controller. The switch the WLC is connected to is a 3750 with IOS 12.2(58)SE2.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
