Contact Cisco TAC is the best

Contact Cisco TAC is the best option.

Most of the time it's type of hardware error.

Not anyone else can you in this matter. TAC can guide or they will tell u to RMAed this device.

As I see in the bug notes it

As I see in the bug notes it's written:

  • Affected releases: 8.0(110.0)
  • Probability of 2504s being impacted is significant; probability of 5508/WiSM2 being impacted is much smaller.
  • Workaround:Replace the WLC.

Why this release is still not deferred? Our customer lost two WLC 2504 the same day!

should we downgrade from 8.0

should we downgrade from 8.0.110 or can we just keep it and keep away from web authentication?
