Can't connect wifi with Intel AC 7265 on Ubuntu 15.10, Asus ZenBook UX305
Please install the latest 7265 firmware. From the terminal:
sudo apt-get update
sudo apt-get install git
git clone https://github.com/OpenELEC/iwlwifi-firmware.git
cd iwlwifi-firmware/firmware
sudo cp iwlwifi-7265* /lib/firmware
Check:
ls -al /lib/firmware | grep 7265
Reboot and tell us if the performance is improved.
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 temporarily:
sudo iw reg set IS
Of course, substitute your country code if not Iceland. 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.
Next, I'd set IPv6 to Ignore in Network Manager: http://docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/images/netconfig/network-connections-ipv6-ignore.png This example is for ethernet, but you want wireless.
If these changes do not help, please try:
gksudo gedit /etc/modprobe.d/iwlwifi.conf
Change the line you added, options iwlwifi 11n_disable=0 to:
options iwlwifi 11n_disable=8
Proofread carefully, save and close the text editor. Reboot.

I've read some postings on similar topics but none of them resolved my issue. I bought my notebook 2 weeks ago. After first wifi problems it worked well for some days. But now, I get almost any connection with Onboard wifi card Intel AC 7265. I tried to add these line to /etc/modprobe.d/iwlwifi.conf:
options iwlwifi 11n_disable=0First I thought this helps, but I only got the wifi password request again and again. But now it's the same as before, can't connect to Fritzbox Cable 7360.
Next I found these two lines in my logs:
[ 1.601664] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-15.ucode failed with error -2 [ 1.601682] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-14.ucode failed with error -2I got these firmware-files from https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware and copied to /lib/firmware. With no effect.
What solution you recommend to connect wifi again. I used a USB wifi adapter but it works very slow and the connection breaks often.

Ohhh, I think you are right. The files are to small. I got the html from github and not the file. ;)
[EDIT 28.01.16] There are many other WLANs in my neighborhood. The router shows 30 other wifi signals. Most of them on channel 11, which is automatically set by ours, too. There are 13 channels in total, some of them are not used by others at the time. Is it recommended to switch to such an unused channel?

chili555 over 8 yearsThe github link you posted includes the -14 and -15 firmware files which you say you copied to/lib/firmware. We wonder if they got copied correctly. Please edit your question to add:ls -al /lib/firmware | grep 7265Welcome to askubuntu. -
chili555 over 8 yearsWould you like a step-by-step to add the newer files?
-
nunatak over 8 yearsI copied them now. Downloaded the raw file formats from github and copied to /lib/firmware. But connection problem still exists....
-
Michael Allen over 8 yearsI have a similar problem since the latest kernel update. Only began happening a few days ago and only on some wifi networks. What kernel are you running?

nunatak over 8 yearsThanks for your detailed instructions. I set the Router to WPA2. 2,4 GHz n+b+g was already set. For now connections seems more stable and performance is good. Hope it remains. Thank you!
-
nunatak over 8 yearsYes it was helpful! Nonetheless I still have trouble with my wifi connection. I often asked for the wifi password repeatedly. After restarting the router it works for a period of time. ;) Maybe there is still something wrong with network settings.

Mostafa Ahangarha over 7 yearsCan you provide any reference? -
Abe Petrillo over 6 yearsFor what it's worth I tested this and it made no difference. Given there is no reference I'm calling BS on this.
