Are we sure that this firmware supports DHCP? It's not uncommon for modem firmwares to lack such support, and I find this a much more likely explanation than the driver somehow messing up the DHCP replies while letting other packets through. Unfortunately there is no easy way to tell for sure if a specific feature is enabled or not in a specific firmware. Is it possible to get a snoop from Windows while connecting, using the modem in the same mode? That would tell us whether the Windows software depends on DHCP or is using the AT^DHCP command.
