Rated a Very Helpful Review
User Rating: Excellent
Ease of Installation:
Ease of Use:
Pros:Routing performance, stability, QoS, true dual band.
Cons:It might be overkill for many standard home networks.
The Bottom Line: A nicely thought out product. It's worth the money if you have a mix of 802.11n and older clients, or need strong QoS for voice/gaming services.
Despite having paid more than I would have liked, I'm really pretty happy with the DIR-855. It's stable. You set it and forget it. Honestly the LCD display panel is something I never tend to use (for that reason). It's fun for 5 minutes at least, though :-) .

Setup is comfortable. The 'wizard' setup pages handle most needs. More advanced users can then go in and tweak around the edges if they wish. In short there's plenty to keep an advanced user very happy, but you don't need to be one to use this router.
I'm in a double brick house and even the 5Ghz signal gets around pretty strongly. I was originally worried because I'd heard bad stories about that upper band not getting through walls etc. It connected at full strength and speed with a Macbook Pro through 2 walls, about 12 metres away.
On the standard 2.4 Ghz band I have one 802.11g and two old 802.11b clients. The signal there is really good. I keep these old standards on this band and the 802.11n clients on the 5 Ghz band so they don't slow each other down. That works incredibly well. If you have a mix of clients like me, I can't stress enough how good the dual bands are.
I've never deliberately stress tested the unit - I don't have the time or inclination. A real world example is the best I can do to illustrate. I have had 2 kids streaming Youtube on their computers, me playing World of Warcraft, and talking on a voice-over-IP telephone call. All of these things are sensitive to network jitter and interruption from each other - especially the phone call. This router handled them all, smooth as silk. Admittedly I've had the same experience before with my previous router, the Zyxel x-550. Both have Streamengine chipsets for their quality of service management. This one has a newer, stronger version of that chipset but they both work. I'm such a fan of Streamengine that I changed from Zyxel routers to this Dlink just to get one that had it. (Zyxel now use a different proprietary QoS system that may or may not work as well).
Dlink just released a new firmware that allows use of the USB port for print and network storage services. I haven't tried it. You need to back your router settings up to disk before you upgrade because it wipes them, but they're easy to back up and restore. Worked without a hitch.
In short I'd say go for it if money is no issue or you need its features now. Especially if you want a quarantined high speed network for your 802.11n clients and a separate one for your older ones. It won't become a bottleneck on a high speed cable or dsl connection, and it handles competing demands from multiple users like a champ.
