The DIR-657 exposes D-Link's standard set of routing features. The shot of the Status page (Figure 7) that you land on upon login should look pretty familar.

There's an online emulator if you want a more detailed look at the GUI, which is standard D-Link. Most of what's listed here is a rehash of what I found in the recently tested DHP-1320. I've highlighted differences with italics.

There are both 20 and 60 second saves that got old real quick during testing.
It's good to see Ubicom based routers coming back. Even though its automatic QoS is focused primarily on managing uplink traffic, it can control downlink speed indirectly by delaying TCP/IP ACKs. Ubicom was the first networking chipmaker to implement auto QoS and they still have the most advanced technology. But if you want to tweak the rules, they also give you 10 sets of controls to do so.
I'm not a fan of USB drive sharing in routers, since it's good only for those who don't mind pretty slow transfers. I ran a quick file transfer speed test with an Iomega UltraMax Pro drive attached and FAT formatted, using our standard Windows filecopy test from our NAS test bed. Write and read speed measured just under 4.5 MB/s.
D-Link isn't very forthcoming with details about SharePort Plus. But it looks like they have eliminated the need to load a driver in order to access shared USB devices. At least I didn't need to use any.
My Win 7 and Win XP machines couldn't browse to the shared drive, but found it fine when I opened a Run box and entered \\dlinkrouter. (The user manual instructs you to enter \\dlinkrouter in a web browser. Maybe that works for Internet Explorer, but not for FireFox.).
I ran a quick check of media sharing features by loading an SD card with a few music, video and still image files and trying to access it from a Win 7 Home Premium machine. The Win 7 machine detected the DIR-657 as a media source and enmumerated and played the few music and video files on the card. It did take about 30 seconds for the five video files to be indexed. So it could be awhile if you give it a big library to chew on.
Note that the only Media server control you get is an enable - there is no way to force or schedule an content index or safely dismount either an USB drive or the internal SD card.
