- As already mentioned ; software version is way too old , go for :
8.5.182.12 (8.5.182.13 for 3504s)

As denoted in https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html
which these days must be considered mandatory ,

@Kasun Bandara 8.5.182.0 is out of date and affected by a number of critical bugs (including security vulnerabilities).
As per Marce's reply the correct version for 5508 is now 8.5.182.12.
