I’ve used this router for some time now and so far it’s been very good.In summary:Pros:- Has 5 GHz range support (very useful in places where 2.4Ghz range is overcrowded)- Supports 802.11ac standard- Range seems good- WIFI speed is very good- Easy to setup and configure the WIFI settings- You can set it to work on 2.4 GHz, 5 GHz and guest networks all working simultaneously- USB port- It’s cheap but has good features (including technologies such as BeamForming)Cons:- Only thing I can think of is it doesn’t have replaceable external antennas if you’re considering adding more powerful antennas later. But in my case, I don’t think I will need to add external antennas.Long story:Because most of my time I stay in an old apartment complex with set old Wi-Fi routers (using b & g ranges, not even 802.11n standard). So the 2.4 GHz range is pretty crowded with many routers (you can easily check the WIFI networks around you and get some idea about the quality by a free mobile app like ‘Wifi Analyzer’). Before this router I had a lot of problems with WIFI connection (connection dropping suddenly, not being able to connect with the WIFI network for long period of time…).So I wanted to find my own router with 5 GHz support. Since almost all of my devices support 802.11ac standard I preferred a router which also supported ac.So D-link DIR-860L seemed to be the perfect candidate, considering its price is just about $30 (just 10 bucks more than a very basic WIFI router).I was concerned about some people saying they got the older version of the router (Revision A), and that version having certain issues. I ordered prepared to return if it shows any issues in first few weeks. I also contacted few sellers to confirm if they have the Revision B on hand (only one seller confirmed they had Rev B. But they too asked me to buy directly from their warehouse listing which was more expensive, rather than getting the one fulfilled by amazon).I bought a one sold by ‘Stop n’ Shop’ and fulfilled by Amazon at about $30, and luckily it was a Rev B model!I have used this for few months now and it has worked very well so far. The 5 GHz range is (still) very clean in my building, so connectivity issues are gone.Only time I had a problem was very recently the router had its lights turned orange (usually its green) and the network was not available to connect to. So I pulled the plug to turn it off for a couple of minutes and then plugged back again. In a minute or so everything was up and running. Hopefully there’d be no issues again.There is an update to firmware available on d-link web, I didn’t bother to update it since so far it’s working well. (I’m using Firmware Version: 2.01)There are apps to control the router settings and the web interface is also easy to use.There’s interesting features such as ‘Beam Forming’ technology in this model. I’m not sure how well those work, but I’d guess they do well considering the performance of the router to be very good.As far as the size, it's not that big actually and looks nice (esp without any external antennas etc hanging around). I've added a pic with a Logitech M705 mouse to get some idea of the size.If you’re concerned, power supply is a 12v and full range 100 – 240vSo overall this router has been very good, will update the review if there’s any new points needs to be added.[...]
