# iwconfig wifi0
wifi0 IEEE 802.11-DS ESSID:"SX551559148"

The output of 'dmesg | grep airo' is:
airo(): Probing for PCI adapters
airo(eth0): Found an MPI350 card
airo(eth0): WPA is supported.
airo(eth0): MAC enabled 0:2:8a:dd:a6:b7
airo(): Finished probing for PCI adapters
So I am under the impression that I should use the eth0 interface instead.
But then 'iwconfig eth0' gives hardly any difference:
# iwconfig eth0
eth0 IEEE 802.11-DS ESSID:"SX551559148"
Mode:Managed Frequency:2.432 GHz Access Point:00:01:E3:55:91:48

And still there's the error message 'No DHCPOFFERS received'.
And there is some difference with the output of 'iwlist eth0 scan':
# iwlist eth0 scan
