I have a D-Link D-Fend DIR-2680 router to sell.
McAfee account not used to it should be good to go - including two years of protection for mobile and other devices.
Opened, tested, not used. Worked with 2degrees fibre (which means support for VLAN ID out of the box).
It should be good for your 200/100 or 400/200 connection. Asking $250 incl shipping.
