Not what I expected from wifi direct, and slow operation.

Turns out wifi direct is only useful from a mobile device without a headache.  Trying to use it directly from a laptop or desktops wifi connection requires you either 1. have a separate wifi adapter just for the printer's wifi connection, or 2. switching your wifi adapter back and forth from your internet connection to the printer to use one at a time.

Also... extremely slow in printing and scanning in comparison to the HP 3160 series I bought this to replace.

Wonderful for LAN supported internet access. However, the WiFi connectivity with this router is excruciatingly slow & drops with a frequency that will drive one to curse like a sailor. After several hours of troubleshooting via Netgear's site, forums, videos, pestering of friends in the tech industry ... I'm done. I'm afraid, this is going back to the seller.

We're survey this for WiFi verification. After tested, connection will drop randomly. Throughput is getting worse very often. Not recommend this to be the base of benchmark.

I bought this to function as an access point as DLink advertises that is has this capability.  I couldn't make it work as one - despite the fact I've set up numerous ones from other brands before.  The feature is present in the most recent firmware, but enabling it caused the device to lock up.  Oh well.

I set it up as a regular router to see how it compared to my Asus RT-N56U.  In comparison to that, I find that it has a weaker signal (slightly, about 2 dB in both 2.4 and 5 GHz).  The Asus doesn't have any external antennas as this does, so I had my hopes up a little I could find use for it.  But when I saw the signal strength was worse, I didn't bother.

In comparison to the Asus, the web UI is very slow and poorly laid out.  The UI would not allow Firefox to remember the admin password for some reason - it kept saying invalid password.  Changing the LAN IP to something other than the default caused the admin password to be reset to something other than the default one or what I entered.  Factory reset required to recover from that.

All in all, I can't think of anything good to say about this device.  Maybe it was cheap??  As a router it doesn't work that great, the firmware is very buggy, and worst of all, it didn't work for the purpose I got it - to  be an access point.

This made my wifi signal worse. Set up was a bit of a headache for me - had to chat with customer service to make it work. Which it didn't really. Even right next to the device the internet browsing speed was awful.

This modem works well as a modem, but as a router not so much.  Signal range is very very short.  Any obstructions at all result in very slow wifi speeds.  Unfortunately I bought this in preparation to use at a later time, and the return window had already closed when I finally set it up and found out this major flaw.  Will be ordering a different one with better wi-fi capabilities

I was very excited when I ordered the AC5400, but when I plugged in and set it up, was let down. Very slow connections and erratic, updated firmware, still slow connections, even dropped down to 6 Mbps on a 5G connection. Ordered a replacement, same thing, slow connection. Even the 2.4G was faster than 5G with MIMO. Decided to stick with my TP Link AC3150 with the consistent 1.5-2.1G connection on a 5G MU-MIMO adapter @ 30 ft thru a wall.

I like what it does...I despise how slow it is to answer. I will have it connected to wifi...with a great signal...and it takes forever to connect. It's a little frustrating.

I like the features and services that come with this product, but connecting and staying connected to a wifi signal is much more difficult than it should be. Mine constantly disconnects and then needs reset to work again

This did not work well for me. It was easy to activate with our internet provider but the wifi was hit or miss. Sometimes it was super fast other times very slow even in the same room or just close by. Within 6 days of purchasing the whole house was kicked off of wifi twice. It came back up after rebooting but I can't have this when I have clients on the line. I purchased from another retailer and will be returned. The Motorola MG7550 I replaced it with runs circles around it. Much larger range and greater wifi speed. I was able to remove 3 of our wifi extenders. Motorola has US support. TP-Link is out of China.

Actually made my Wi-Fi slower.  I returned it and are continuing to use my dinosaur of a router with better results.

Didn't really improve the wifi signal in both of my store. It's kind of a disappointment

the connection is extremely slow and it is not because I got a bad internet connection.

After having this for almost 2 years,  I feel as though the initial $300 price tag wasn't justified.  The 5 Ghz band continues to be choppy and bottlenecks,  even with one device on it. The QoS works but definitely slows down all wifi connections regardless of priority.  Its been almost 2 years,  so I'm looking to upgrade to something better.

I bought th RE6700 Linksys AC1200 wifi extender at Walmart not at Amazon but I usually buy much of my tech through Amazon. This unit has been very disappointing. I went through the manual setup as the wireless router from the ISP provides me with no administrative control. I was easily able to get the extender to connect to the router and have it fully setup in minutes when it was only 15 feet away from the router. Upon attempting to move it to a kitchen outlet, just under 4' off the floor and 18 ft. away it had issues staying connected. I tried another location with even fewer obstructions just over 30' away and it connected and then fell away again. I moved it to a more elevated location with roughly the same amount of obstructions, minimal, and then it connected for a few minutes and then lost the connection. My iPad and Samsung tablets can both connect with 2.5Ghz and 5Ghz fine in the same location. From the middle of the small house less than 30' away pretty much all the devices connect. In the back of the house I can even stream to my iPad on the 2.5Ghz radio but the signal is weak due to obstructions. Well, for an extender to be in the middle in a zone where pretty much anything connects and holds solid is pretty lame. Would  I recommend this? Not based upon my experience. I plan to return it and move on to another solution.

It's slower than I thought it would be.  Could be the network. It's done all I need it to do.

This review is for the D-link DIR-820L model.

I purchased this router to replace a five-year-old Netgear that had begun dropping signal. Because I have a lot of Apple products I wanted to test the AC technology. I can honestly say that this router, as far as signal strength and speed, performs much worse than my five-year-old Netgear. I guess it is true that you get what you pay for.
The included cable is much too short. My network stand is about 4 feet tall. However, connecting the AC plug to the router and then the power strip has to be manipulated so that the router is on the very edge of the 4 foot tall table. Most other electronics that I home come with a six-foot cable. This connection is a straight up-and-down shot.
I can say that set up is very simple. Although I don't like using the application it's seem to be the best way to set it up since going to the website kept telling me that my router it was not connected to the Internet. Once set up, I expected both better reception and higher speeds. I can honestly say I was terribly disappointed. One room over (about 15 feet on a shared slat and drywall wall)  and my iPad drops to two bars on the 5 GHz side.  My Fire TV stick, one room over was almost unable to connect at all without actually turning the television around to get a clear shot.  Once connected, video performs just fine.

My rated Internet speed is 60 Mb per second. Testing on the 2.4 GHz side resulted in speeds of 14 MB per second. The 5 delivers almost the rated speed but no better than the 5 year old router. This is not acceptable. I settled for this router because the rating on both 2.4 and five should be more than enough to handle my 60 GB connection. Because the distance between connected devices is not huge it would think that there would be no problem connecting with the latest technology. But the 2.4 and 5 MHz frequencies on my old Netgear performed much better. I generally would not lose signal on my mobile devices until I was a good way away from my house. I think I need to clarify that the Netgear was not the most expensive device either.

I am also not impressed with the provided software. There is no application to really control the network other than going to the website. I find this cheap and bothersome. I have no desire to break out my laptop every time I want to make a network adjustment, a simple reboot or if I want to check the statuses on my network. I would like to be able to control access control etc. from a one stop app. D-Link dropped the ball on this one I become so used to this on all other wireless networking devices I have used.

The fate of this router is going to be one of two things, I haven't decided. It will be returned to Amazon or used  to set up a range extender. I do use devices in the room in which the router is located however I don't want to be relegated to only using wireless devices in the room in which the router is located. Since I do a lot of work from my home office the ethernet ports may be the tell. Even rated at 1/100 this should be able to handle my hardwired needs.
