Features

The 827's feature set is a duplicate of the 657's, with the addition of a second set of wireless controls for the 5 GHz radio. A shot of the Status screen is shown below.

D-Link hasn't posted an emulator for the 827, but you can use the 657's if you want a closer look at the admin GUI.

Here is a feature summary, copied from the 657 review.

Routing

  • DHCP, Static, PPPoE, PPTP, L2TP, DS-Lite WAN types

  • Ubicom automatic uplink QoS with manual / automatic uplink speed detection and manual rule option

Wireless features

  • WEP, WPA / WPA2 Personal and Enterprise (RADIUS) support
  • Wi-Fi Protected Setup (WPS) support, pushbutton and PIN
  • Auto and manual channel set
  • Transmission rate set
  • SSID broadcast disable
  • Wireless modes: b-only, g-only, n-only, mixed b/g, mixed g/n, mixed b/g/n (default)
  • High / medium / low transmit power adjust
  • Beacon period, RTS threshold, DTIM interval, Fragmentation Threshold adjusts
  • Wireless client isolation (from each other)
  • WMM disable
  • Ubicom WISH automatic wireless traffic QoS
  • Short GI disable

Sharing features

  • UPnP / DLNA Media server enable
  • SharePort Plus drive and printer sharing
  • Sharing to/from embedded SD card reader

Missing features

  • WDS bridging repeating
  • Physical wireless disable button
  • AP / Router mode switch

The 60 second saves got old real quick during testing. But at least you can make changes on multiple pages before saving.

Since this is a Ubicom router, all of its features are there. Ubicom's automatic QoS is focused primarily on managing uplink traffic. But it can control downlink speed indirectly by delaying TCP/IP ACKs. Traffic shaping is enabled by default, as is automatic measurement of uplink speed. You still get only 10 sets of rules if you want to tweak Ubicom's selections.

File Sharing

Like the 657, the 827 includes D-Link's Shareport Plus drive and printer sharing feature. There are no storage controls in the router's admin GUI except for a media server enable/disable (enable is default). You need to download the Windows or MacOS Shareport Plus utilities to share printers or if you want auto-discovery of shared drives.

You can reach the drives by opening a Windows Run box and entering \\dlinkrouter. You can also enter \\dlinkrouter in Internet Explorer, but not Firefox or Chrome. Download the Shareport Plus manual for more info.

The only formats supported for read/write are FAT and FAT32, so you're limited to 32 GB volumes. I ran our standard Windows filecopy NAS test to an attached WD MyBook 3.0 USB 3.0 drive and got 11.5 MB/s write and a surprising 25 MB/s read! This is a big improvment over the 4.5 MB/s read/write I measured with the DIR-657. Running the same tests to a 8 GB SD card yielded 3.7 MB/s write and 11.4 MB/s read.

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. File indexing was pretty fast, but I had less than a dozen files on the test SD card.

As noted above, 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.

Routing Performance

Routing throughput running the latest 1.01 firmware, our router test process and with QoS/traffic shaping disabled, measured 680 Mbps WAN to LAN, 721 Mbps LAN to WAN and 1,056 Mbps total with up and down tests running simultaneously. If you can really use this much routing throughput, you probably shouldn't be looking for a $160 router! The IxChariot composite plot below is hard to parse given the throughput variation. But looking at the legend for the simultaneous updn test we see upload throughput lower than download

Maximum simultaneous connections maxed out at our test limig of 34,925. In all, the 827 should provide fast, stable wired routing.
