What is the Mfr and model of the AC device your connecting to the router.

As a quick test, disable WPA security on 5Ghz radio temporarily and then try to connect the AC device to the 5ghz radio, does the router still reboot then? Re-enable WPA2 after testing.

Devices: Apple Ipad Air 2, Apple iPhone 6s and Moto X Style (Pure Edition in US)
The router still restarting when connected any of the three devices without WPA security.

You might do a factory reset, manually reload the FW file, factory reset then set up from scratch.

Should I try the firmware 2.00 or 2.03 ?

Either one...can try both if you want too...I presume if either don't work then I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.

Enjoy.  ;)

Got the same issue with my galaxy tab s2,  the support send me a 2.04 beta version, problem fixed. If you wish to fix the issue on other firmware, change the 5ghz channel from auto to a fixed value less than 3 digits.
Hi, I bought this router a few days and when I try to connect any wi-fi ac device, the router restarting until I switch off wifi in my device. Any help or ideas?

Different case for me, my Nexus Player refuse to connect to AC if channel is two digits, need to change channel to 3 digits for it to connect.  In any case the B1 version of firmware has too many security loop holes, wps can not be disable is one big no no.  Flashed to Tomato firmware and call it a day.  Overall  imo Dlink should do something about this new style firmware.  simple for newbies or non tech is ok but should not given up security for simplicity.

Link>Welcome!

  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?

Users are encouraged to report possible security vulnerabilities here:
http://support.dlink.com/ReportVulnerabilities.aspx

We see in other DIR series routers were WPS feature as added so users can disable it. Not sure why it wasn't on this Rev B model.
This specific Rev B model router is not sold in the NA region so I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.

Thank you.

This is my second Dlink wireless router and to be honest my 1st Dlink Wireless router was also my 1st wireless of any kind, I think it was in the late 90's or early 00's, it was a wireless b router, had it for 10 days and returned it, the firmware then was a joke, I needed to reboot it at least twice a day.  Fast forward to May 2016, if not I saw this DIR-868L at a very attractive price sitting at my local Staples's clearance bin and I know it has ddwrt and Tomato support, I wouldn't touch another Dlink.  If you google "dlink router Vulnerability" you'll know what I mean.

Anyway, thanks for the links but to be honest if Dlink is serious about their firmwares, they would have fixed it many years ago.  Finally, don't worry, Dlink is not the worst, Dlink is still fighting with Tplink for this title.  If you were a Dlink staff, I hope you are not offended, I am just telling what I  (as a consumer) think about Dlink wireless router.  Finally, I have a Dlink 4 port gigabit switch and a DNS-320L working fine within my home network.
