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 st

TCP SACK improvements (RFC6675 rescue retransmission and lost retransmission detection)
