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=0
First 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 -2
I 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?
Best Answer
Please install the latest 7265 firmware. From the terminal:
Check:
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:
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:
Of course, substitute your country code if not Iceland. Set it permanently:
Use nano or kate or leafpad if you don't have the text editor gedit.
Change the last line to read:
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:
Change the line you added,
options iwlwifi 11n_disable=0to:Proofread carefully, save and close the text editor. Reboot.
