side note: a Nokia mobile phone can do DHCP successfull with the same AP, i.e.
there is no MAC addr blacklisting in the AP;

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
side note: a Nokia mobile phone can do DHCP successfull with the same AP, i.e.
there is no MAC addr blacklisting in the AP;
while running the above DHCP a tcpdump on the interface ath0 produces the output below;
it seems that the MAC addr of the AP is seen (Etherframe) but the rest is not
decodeable (crypted or compressed?):
# tcpdump -n -i ath0 (for dhclient -d ath0)
