Well, I bought one and it dropped signals every 2 minutes. No matter what I tried - updates, reinstalling, unplugging and replugging.. Nothing worked. So I returned and got a replacement thinking well maybe I just got a dud?
NOPE. This one started off great, didn't have a single disconnect but after the first day it started. It was minor at first only maybe once in the evening, but then it started to happen every 3 hours and I have smart devices this stupid thing would disconnect me from enjoying music or shows and I'm so fed up of having to try and fight with it. That I just caved and am going with the Amazon Eero (literally set up and already working great).
Whatever you do, if you buy you're taking a risk. If you can handle drops go for it but it's annoying as all heck when you're trying to relax after work.
Also for anyone wondering I use V-Media and the direct link to my pc with no wifi is great, no drops so it's not a modem thing. It's literally D-Link needs to get it together.
Performance: The WiFi 6 technology really makes a difference. Whether streaming 4K videos, playing online games, or managing smart home devices, the connection is consistently fast and reliable. I noticed a significant improvement in speed and reduced latency, even with multiple devices connected simultaneously.
AI Features: The AI-driven optimization is a standout. The router automatically adjusts to deliver the best possible performance. It also has intelligent traffic prioritization, which ensures that essential devices or applications get the bandwidth they need without manual configuration.
Range and Coverage: The coverage is impressive! I’m able to get strong WiFi signals in areas of my home where my previous router struggled. If you have a larger home or want solid coverage in every room, this router delivers.

- The router has great range and easily beats anything else I've tried in this price range! I live in a crowded downtown area with loads of interference and can maintain a connection down the street.
- The setup interface is super easy, so much so that my mother was able to do it without asking me any questions.
- Nice modern look
- Great throughput, regularly maintaining over 900 Mbps for local streaming on AC.
- Overall performance seems above average for the price
The Bad:
- Super simple interface is frustrating for power users who want complete control (If this is you I would chose another model)
- I noticed some AC based devices needed a second attempt at connecting to the network. This would result in devices taking a few extra seconds to connect. Not a huge deal, but will probably addressed when the router gets its first patch.
Verdict:
I would recommend the router to anyone who needs a great mix of speed and rage in the sub $160 price point. You really can't go wrong with this one, just keep an eye out for software patches.
Tech support was the usual, have you tried switching it off and then back on again to start with until i got put onto somebody that had a rough idea of what was going on, we went through various settings, but the issue was never resolved.
I may have had a faulty unit, i don't know but I was offered a replacement but declined the offer and sent the unit back to amazon for a refund.
I've had plenty of D-Link routers in the past, but this one was a big disappointment and to be honest has put me off D-Link routers for life. I replaced it out with a Linksys E7350 router which surprisingly wasn't made in China and was easy to use and setup.
owned in a long while.

This router is very fast, works great, and quite flexible in its quality and settings. I have been using dlink routers for at least 18 years and have never had an issue with any of them. 5 stars all the way.
The best feature of this router is, the "smart connect mode" which does not require you to have the two different SSIDs for 2.4GHz and 5GHz wifi. You can just turn on the smart connect feature in the router settings and that requires you to have just one SSID. Whenever you connect any device to the router, it automatically decides which device to provide 5GHz coverage and to which provide the 2.4 GHz coverage.
For example: If I connect my TV which is not too far from the router, the router will automatically provide 5GHz coverage to it. And, when I take my phone a little far and then try to connect to the wifi then it will connect to 2.4GHz because 2.4GHz has better range than 5GHz.
This kind of smart features makes this one of the best router in its segment.
I have my TV, 4-5 mobile phones, 3 laptops and an iPad always connected to the wifi and this router excellently manages decent coverage and internet speeds to all the connected devices.
Although, I was a bit skeptical before investing such a large amount on this router, I am very happy right now with my decision to purchase it.

Upgraded to this from a Dlink 850L AC1200 unit. Great upgrade overall. The 850L had inbuilt antennae and I hate using range extenders despite having 2 of them since they affect literally halve the speeds.
This beast though covers my home perfectly and remains stable.
Setup : Setup or the ease of it is the number 1 thing I love about Dlink routers. This literally took me 2 minutes to setup. And atleast 1 minute 45 seconds went in the actual plugging in the power and Ethernet cables. The actual config took barely 10 seconds. I just followed the setup wizard in the router config page and it flew like a breeze. Bridge mode from my ISP modem. Open NAT. Superb speeds. Continue to be a Dlink fan.
