Hi,

I'm unfortunately too busy to really help you dig into it.

I'd start by using tcpdump on wlan0 to see what's going on - see if
it's sending/receiving DHCP responses.

Then I'd look at if_iwn_debug.h and enable TX/RX debugging - see if
it's actually transmitting the DHCP requests and the TX status code is
OK rather than one of the errors.
