My ISP, Plusnet sent me a DGN2200 last year. Unlike the DGN2000, the ports keep working. I just use the router as an additional switch and as a 2nd 'n' wifi point.
This year Plusent sent me a 582n which I use for my DSL connection with 63dn downstream attenuation.
Both routers were supplied FOC.
The 582n does port translation which the DGN2200 can't do.
