Intel AC 7265 NGW support for Linux?

I am running Ubuntu Linux on an Acer V Nitro - VN7-571G laptop which uses an Itel AC 7265NGW wireless module. Quite often the system loses WiFi connectivity with the router, I guess this is a driver issue since the other Windows laptop works fine, and also the other devices: Chrome Cast, Android phones and tablet. Where can I find a proper driver?

Thnx for the reply, it was really helpful even if it didn't really solved yet my problem. I am a novice with Linux, so I may not know some aspects.

Linux is different to Windows regarding the wireless drivers which are delivered along with the kernel. Intel only supports the kernel team developing these drivers, which will be shiped with the kernel. So some one must check what is the right version of the kernel for his/her PC. Here is the official list from kernel.org: https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi This adapter is supported starting with kernel version 3.13. I shall check on my laptop what kernel do I have and address the issue on the communitiy mailing list.

UPDATE

aleki_intel I checked my Ubuntu kernel version and it is 3.13.+, but I still have frequent disconnects. I will try to enable the logs for the WiFi card, maybe they are self-describing, we will see.

Hello Sandu,

Please check the AP configuration as also external environment could be affecting.

aleki_intel for the moment I "solved" the issue through an work-around: I had disabled 802.11N and now the connection is stable. Of course, I am not using anymore the full capacity of the 7265 controller, but it seems that there more problems in the Intel iwlwifi driver. Until a real fix will be available in the kernel/firmware will be available, I can live with that. But it seems that I am not the only one have this issue, because I found it described on this blog post: http://zeroset.mnim.org/2014/04/22/unstable-wifi-connection-on-ubuntu-14-04-trusty-tahr-ctrl-event-d... Unstable wifi connection on Ubuntu 14.04 Trusty Tahr (CTRL-EVENT-DISCONNECTED reason=4 locally_generated=1) | zeroset

My kernel/firmware versions are: 3.13.0-45-generic/22.24.8.0 and I am using also Ubuntu 14.04 Trusty Tahr (a little bit newer 14.04.01 in fact)

 

But in the /var/log/syslog I have similar messages:

 

wpa_supplicant[1214]: wlan0: CTRL-EVENT-SCAN-STARTED

(...)

wpa_supplicant[1214]: wlan0: WPA: Key negotiation completed with [...] [PTK=TKIP GTK=TKIP]

Hmm, I wouldn't say that the issue had been resolved. This is more like an work-around which is acceptable for time-being. The real solution shall be in the kernel and firmware, but of course this is not in Intel hands. As a general advice in the future when buying PC for Linux usage, it should be verified if it is completely supported by the vendor for Linux.
