Aironet 1240 - Cannot Set Time

[ken]

I am attempting to correct the time on my Aironet 1240 AP.  However, when I attempt to update the setting and "apply" them, I am directed to an invalid "page", and the accesspoint will not update and accept the setting. There is currently an invalid IP address in the "IP or Hostname" field, and even if I attempt to disable SNTP, I am directed to the same invalid page.  I appreciate any help I can get.
