Even though it is based on a different chipset than D-Link's other products, the admin interface has the classic D-Link router look shown in the Internet Connection screen below.

Thirty second reboots are required to save setting changes. But at least you can make changes on multiple screens and save once. Given D-Link's aggressiveness in supporting IPv6, it was a surprise to see support missing on the 605L.

D-Link hasn't posted an emulator for the 605L. So I've posted most of the key screens in the gallery with explanatory captions.

Routing Performance

Routing throughput running the latest 1.11 firmware and our router test process measured 87 Mbps WAN to LAN, 86 Mbps LAN to WAN and 133 Mbps total with up and down tests running simultaneously. This is a bit lower than most other routers that I judge 100 Mbps "wire speed". But, in reality, you would be hard pressed to see a difference.

Maximum simultaneous connections topped out at a relatively low 6,483. But again, this number is more than sufficient for a home/SOHO router.

The IxChariot plot below shows a moderate amount of throughput variation under the high continuous-traffic load of our test scripts.
