Description:         Firmware for Intel (R) Dual Band Wireless-AC 7260


I also tried the firmware linux-firmare, but is the same.

I don't know what to do. Seems a problem of frequency or a buggy kernel. Anyone has experienced with this before?

Thanks in advance for the support!

EDIT 1:


Today I switched from gentoo-sources 3.17 to 4.0.5, but I still have problems... here the errors:

I had similar problems with a 7265 intel wifi chip, and only now, about half a year after purchase, kernel driver and firmware work in a way that can be called kinda reliable. Consider upgrading to linux 4.2, and try downloading the latest firmware compatible to your kernel from this list:
