Moin!
Mein FB7170SL läuft seit der vorletzten Version nicht mehr mit meinem W2K Rechner:
Keine Beantwortung von DHCP discover requests, keine Arp replies, nix.
Mit einem zweiten Rechner mit winXP läuft alles.
also auf dem XP Rechner DHCPdiscover-offer-request-reply
auf w2k DHCP-discover-discover-discover ....(die zeitlichen Abstände vergrößern sich)
also mal wireshark angeworfen und die beiden DHCP discover verglichen:

bei der älteren Firmware 29.04.59 liefen beide Rechner einwandfrei, d.h. bekamen eine IP-Adresse. Die Fritzbox war jeweils im Werkszustand
Welche der beiden DHCP requests ist denn nun RFC konform?
