I was really unhappy with this D-Link router. My thermostat and printer would disconnect and not run reliably on D-Link's combined default 2.4/5ghz network. After much troubleshooting I finally figured out I could split it into a 2.4ghz network and a 5ghz network. Then the 2.4ghz equipment worked fine. I have recently installed a tp-link w6000 mesh router where the combined single network implementation actually works for both my thermostat and printer, which is a good thing since TP-link doesn't let you split it into 2 networks. The TP-Link implementation of that combined protocol is just better. Also the D-Link router quit working with my modem after 18 months & my internet provider's tests showed it was a router problem. I called D-Link support and they said any support would cost me $70 since I had it over 90 days, so forget that. Since the 1 year warranty expired I bought a $130 TP-Link W6000 mesh router that works well and has a stronger signal upstairs since I now have a node both up and down.

Bought this router Aug. 1st, and it was dead on Sept 16th. It was fine the night before, when I got up in the morning it was dead. No lights, no function, nothing. It was plugged in surge protected strip with other network equipment, all of which are ok. I've owned D-Link networking equipment for 25 years and it was always great, but I guess it isn't anymore. I sent emails to customer support, nothing. I chatted with "customer support" and they said I had to CALL customer support. I got to their website to call customer support, and they have posted across the top "Phone support services may be limited due to high volume. For a quicker response, please use Chat services." I guess it pays to make crappy equipment if customers can't warranty your product. Time to buy an ASUS I guess.

Slowed me down. Put most of my 5GHz devices on the 2GHz network. Refused to allow many of my 2GHz devices to connect. it gave few choices in how to configure. It could only go in router mode, (double NATting from my fibre modem/router), or extender mode, (connecting wirelessly only to the modem/router, with slower speeds). Access Point (AP) mode and bridge mode were NOT options, both of which my Netgear AC1750 offered.All in all, worst connection, worst speeds, worse flexibility, useless product….…Unless you have a cable modem (no router) which offers a direct connection to a router. In router mode, it kinda worked, but segmented my networks so devices on the East side of my house could not see devices on the West side of my house, and vice versa.In extender mode, If I put it West enough to see all my devices, it only gets a weak signal from my modem/router. If I put it where I can get a strong enough signal from my modem/router, it can only give a weak signal to my westmost devices.Sure, one solution is to move my modem/router more West, but then that would entail moving my wiring closet, and my eastmost devices will not get a strong signal….[EDIT] I have a Cat5e cable from my wiring closet to the West side of my house. Being wired means I do not need Wi-Fi extender, but a bridged router. This treats the Router as an AP, putting all Wi-Fi clients and LAN clients on the same network as its WAN network, (which would be connected to the LAN side of my East-side fibre modem/router. [TIDE]Will be returning for a Netgear or Linksys model.[UPDATE] Got a linksys model with bridge mode. Returning this. [ETADPU](P.s., I have stupid —but fast and cheap— AT&T fibre Internet, which comes with a rented modem/router. There is no 3rd party replacement device available, —in violation of federal guidelines,— so replacing that with a modem only device —to connect directly to the D-Link in router mode— is NOT an option, and I would still have to get a second AP for the West side of the house.)

UPNP works but painfully slow @ 20MBps. Upgraded firmware with no success. Spent 2.5 hours on a chat with D-Link only for the rep to tell me to "live with it, it's better than nothing" and then disconnect from the chat! Seriously??? I returned the router the next day and will be hesitant on buying another D-Link product! Decided to go with the Netgear NETGEAR RAX50-100NAR and it works flawlessy. UPNP is running at full speed @ 110 MBps over gigabit LAN.

I bought this wifi router to replace a TP Link wifi router. When I hooked it up the internet connection on it kept dropping every 63 minutes exactly. I tried updating the firmware and a variety of other troubleshooting things, but I could not fix it. I looked online and apparently these Dlink routers are notorious for having problems like this. Dlink really needs to improve their QA, as this router costs too much money to be performing badly like this. I am going to try hooking it up one more time, but I was really not happy with how things went the first time when I tried to use it. I give it 2 stars.

Speeds and coverage were good, the GUI is pretty user friendly. However... After about 6 months it just stopped detecting any internet in from the modem, and to technical support costs $25 per CALL after the 90 day 'free tech support' window. I've never heard of a company not offering full aftercare for their products up to the date that they stop support entirely. Would not buy again.

My D-Link EXO|AX AX5400 was fine for about a year and a half and then it stopped working. It cannot see the internet connection from the cable modem suddenly. All hardware was up to date on firmware updates. I'm outside of the manufacturer's warranty and didn't happen to buy the Asurion insurance policy I'm out a router. I just ordered a new router of a different brand. Very unhappy to have spent $123 for a router that lasted 1.5 years.
