Excerpt: It's good AP with greatly decent design. In this form, it can be virtually in any room and what I appreciate a lot: it has only two rather low intebnsity LEDs which don't blink. Also, the absence of antennas is great thing. Technically, I really appreciate the gigabit switch. Slightly worse is the configuration interface which is rather oudated from design point of view and some time rather non-intuitive and illogical also.
Pros: Very nice and in the main decent design.
Cons: Configuration can be more well arranged; it's slightly non-intuitive some time.
Excerpt: I bought this specifically to take advantage of the 5.4ghz band and have not been disappointed with the improvement in performance especially with the saving of files to an attached hard drive.
Pros: Easy to set up. Fantastic upgrade to the standard Etisalat router giving the advantage of dual band coverage. Can attach a standard hard drive for fast wireless file copying.
Cons: Coverage in multi room apartment a bit iffy, but easily resolved with a range extender.
Summary: My DIR-850L (hardware version A1) arrived with 1.05 firmware (Apr/2013). It had trouble getting an IP address from my cable modem (so wouldn't connect to the Internet). However, once I upgraded to the 1.12 firmware (Dec/2014) everything worked just fine. My recommendation if you're UPGRADING to this device from an existing router is to download the latest DIR-850L firmware to your computer BEFORE you shut down your existing router.
Summary: I live in a very crounded neighborhood and the 2.4Ghz band is getting pretty full. I have started moving my systems to 5G and that is helping, but the range is not so hot. I recently purchased a couple of PC's that came with AC cards, so I started looking at AC routers. Despite my poor experiences with D-Link in the past, based on the reviews and the price, I decided to give this on a try. I am glad I did.
Summary: It is just OK. The browser set up was a bit difficult versus my old netgear router. What set this off for me to purchase over any other router was the shelf space it takes. I have a wall mounted convergence box and the recent size of the wireless routers have made them too big to fit in my enclosure. This unit was the only AC gigabit router that fits so I had to give it a chance. We are still using it, but I got to find a replacement eventually.
Excerpt: I use this router to connect my wireless mobile devise as well as gaming system and home surveillance camera system. The setup was a breeze and the signal is much faster than either of the two Linksys routers I had been using in the past. Two thumbs up to D-Link for making such a great product available to the masses.
Pros: Easy To Set Up, Fast, Fast Connection Speed, Reliable connection, Secure Connection
Summary: Router works great. The range on the 5 ghz side of the router seems a bit low. The picture on the back of the box shows the DIR-850L as not having the same range as the two higher end wireless routers. This would have been nice to know before I decided which model to purchase. Also it does not have Smart Beam. I thought that all of the wireless routers with this style antennae array had Smart Beam but this one does not. This was also disappointing to discover.
