Wifi connection not working with Intel NUC + Wireless AC 7620
Solution 1
I have a NUC as well and found that several minor quirks were fixed when I updated the BIOS to the latest. I urge you to do the same.
Next, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.
Next, I recommend that your regulatory domain be set explicitly. Check yours:
sudo iw reg get
If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then, set it permanently:
gksudo gedit /etc/default/crda
Use nano or kate or leafpad if you don't have the text editor gedit. Change the last line to read:
REGDOMAIN=IS
Proofread carefully, save and close the text editor. Of course, substitute your country code if not Iceland.
Reboot the NUC and let us know if stability is improved.

i also had this issue with intel nuc skull. driver and bios update didn't help. but switching the channel in my router from "auto" to channel "1" did the job.
Solution 3
Hi again and thanks for the feedback,
So here is what I did:
- BIOS update: done with the release of June 12th 2015. The version previously installed was about one year old.
- Router settings: I had selected WPA (TKIP+AES) because it is stated in my router interface that this is the prefered mode (does not say why though). My other choices are: WEP (but I would disregard this due to low security), WPA (TKIP) or WPA (AES/CCMP). Do you recommend one in particular ?
- Router channel was changed from 13 to 6.
- Exclusive use of N mode of the router: the option does not exist one way or another in the interface. However I am quite sure that the router is not in N only mode because my nettop only support B and G and still is capable of connecting to the wifi.
- Router reboot done.
- The output of iw reg get was indeed 00.
- REGDOMAIN has been changed from 00 to FR.
- The output of iw reg get is now FR.
- NUC reboot done.
I made of few tests yesterday and the wifi response is clearly better. I was able to update through apt-get with a download speed within 500 to 700 ko/s (which is OK I think). Internet browsing was very fast. Today is maybe slightly slower, but hard to tell.
It looks like the issue is solved, but unfortunately, I have been used to these temporary improvements in the past. Let's consider this closed for now and I will post back if the problems show up after a few weeks/reboots/updates.
Thanks again !

I am posting here with the hope to get help to solve the problems I have with my wifi connection on my Intel NUC with the Wireless AC 7620 on Ubuntu 15.04.
I have copied below the output of the Wireless Info Script, but before some short history and description about the problems I have.
I built my NUC about a year ago and installed Ubuntu 14.04 straight after for a media center use. Everything was working perfect, with fast and stable wifi connection. When Ubuntu 14.10 was released, I didn't upgrade (I wanted to stay on a LTS version) but kept doing the regular updates.
Then one day to another (somewhere around October / November 2014 I would say), everything went wrong: connection to the wifi was lost on a regular basis, sometimes every few minutes, transfer rate was dropping so low it would take several minutes to display the Google homepage, the connection would get lost and never come back.
I went through several forums/websites/wikis and tried many things. What got the best results I think was to disable the power management with iwconfig. Disabling/renabling the wifi and/or network was working also sometimes. Upgrading to newer Ubuntu version was sometimes improving the situation, sometimes not.
Today, I went back home and wanted to use my NUC again and the situation is worse as ever. Here are the symptoms :
- The NUC quickly connects to my wifi network at startup.
- The signal strength is good, to about 75 % I would say.
- The connection is stable.
- It is impossible to get to any website. If I try to reach the Google homepage for example, the Firefox wheel will turn for ever but nothing shows up.
- Trying to update with apt-get update does trigger some data transfer, but at a very low transfer rate (I cancelled it after five minutes and it wasn't finished).
My router/internet access is a Freebox v5, but I think the problem really comes from the NUC/Ubuntu, as I am also running a Windows 7 desktop and a Debian Jessie nettop on wifi and none of them have these problems.
Thanks in advance for your help !
Any additional command line or test, let me know and I will do it ASAP !
Note: I removed all wifi networks that weren't mine from iwlist scan to stay below the 30000 characters limit.
