Do you know exactly what that repeater configuration is doing? Is it
supposed to extend range of AP (using Host AP driver)? Are you sure it
is compatible with Host AP driver?

Associated with which AP (Host AP/D-Link DWL 900-AP+)?

Reason codes are defined in IEEE Std 802.11 (3 = deauthentication
because sending station is leaving or has left).

I would assume that the station re-associated with the D-Link AP and
Host AP is removing it after timeout.

Here the station re-associated with Host AP..

.. but, for some reason decided to deauthenticate.
