D-Link Support today told me on the phone that the DXN-220 component of the DXN-221 kit has only _one_ coax port. That agrees with what I saw 1.5 months ago, when the Dlink.com site was still showing a picture of the back side of the DXN-220.
However your review, Tim, includes a picture of the back side of a DXN-220 that has _two_ coax ports. That agrees with D-Link's January announcement of the DXN-221 kit, which included a similar picture showing two coax ports.
Tim, it is possible that (as I suggested in a post on the Netgear MCAB1001 thread) D-Link originally designed the DXN-220 with two coax ports, but changed it to one port before they shipped in April. Are you sure the kit you reviewed was what actually is shipping?

Or did you use your flux capacitor to obtain a copy of their _next_ revision to the DXN-220?
I took the liberty of mentioning your review to the D-Link sales support person I spoke to, and he suggested that you contact Alfred Loya,
aloya@dlink.com. Another contact address would be
productinfo@dlink.com.
