I did not see any dhcp-messages in the log. Are you sure, that
dhcp is activated on the AP. What kind of AP is it? Am I right,
that the AP is AP and also Router to the internet?
Are you receiving this "email warnings" that along the long
have been sent?

About the *smurf* you may watch:

ressources you may find with your favorite search-engine).

Not the solution, but you may try to set your card to a fixed-
adress in the network (eg /

The command for manually up/down with dhcp on SuSE is:
ifdown-dhcp "interface" and
ifup-dhcp "interface"

ifdown-dhcp wlan0

This does not only a up/down of the card, but sends also the
apropriate commands to the dhcp.
