Summary: I always bought a D-Link router since needing one because it always worked well and it was easy to install BUT I won't ever again purchase another D-Link. First of all my last D-Link router lasted less than 6 months. It was great while it lasted. I have tried 3 days to get this one to work. I am so disappointed and frustrated. I wouldn't recommend D-Link Dir-857 Dualband HD 900 Mbps 4-Port Gigabit Wireless N Router(DIR-857)to anybody in good conscience.
Dlink needs work in their customer service department

Summary: Bought this router because of the good reviews. It worked great for about a year then it suddenly dropped one hard wired line out of the three. I spent a great deal of time trying to fix the computer that had the dropped line since none of the other two had a problem. After two calls to tech and about three hours, customer service condemned my ISP's modem. I have had problems with other Dlink products in the past so this will be my last.
Summary: I have used D-Link routers exclusively for at least 15-20 years. The last two that I had were the DGL-4300 and the DGL-4500. With both of these, they almost never had to be restarted and worked flawlessly. Since I had the DGL-4500 for over 5 years, I had been told that they eventually wear out, so I decided to get the latest and greatest HD router from D-Link assuming that it would work as previous router had. I am so sorry that I did.
Summary: What a pain in the a... This first order came and just from the start router did not work. 2.4Ghz antenna did not sand signal. Called D-Link tech support, talk to Indus tech support, got my RMA to get new router, receive new router and you would think that's over? Wrong! When I open a so call "new replacement", the replacement was all damage, scratches everywhere, simply refurbished.
Summary: I am going to do my best to be short and sweet: -- I used to have a DIR-655. It served me well for years until it died. It happens. By the time an AP dies on me, I'm fine with the excuse to upgrade. That router sold me on D-Link. -- I bought the DIR-857 September 2012. After about a month, I noticed that although 2.4 was broadcasting, I could not always connect to it. So, I would connect to 5.0. Fine with me and did not think anything of it.
Summary: I bought this product as we were having cut offs in our video stream on the internet. I assumed that the problem came from our outdated router. This product did not improve the situation. perhaps through my ignorance I assumed that the media streaming would work with all computers but it was very selective and only worked with one of mine. Additionally in media mode the range is much shorter. I had some problems with set up and asked D link for help.
Don't like this router, going to get rid of it and go back to Linksys

Summary: Hard to set up, keeps dropping the signal on the 2.4 ghz band. Have to reboot the router to get it working again. This happens several times a week. Tech support was not able to cure the problem. Read a review on Cnet that recommended it but it has not lived up to their recommendation.
