I use madwimax to connect that modem, I do not use ifup/ifdown at all. Both ifup and ifdown respond smth like «ignoring unknown device wimax0». When I'm done with my wimax network, I just unplug the modem from the usb port without manual invocation of any command.
There is no dhclient for wimax in the process list. However there are lots of dhclients for wlan0, I'm surprised: # ps aux|grep dhcl root 461 0.0 0.0 7256 672 ?
