I'm using the ubuntu 15.04 (kernel 3.19+) but the driver that I'm using it's not working well. Comparing it with widowns I'm losing ~50% of signal.
I'm comming from linux mint that also wasn't able to use the correct driver or configuration. I already tried change kernel version and install the drivers in this list: https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi#Firmware The last one that I tried was: 3.19+ iwlwifi-7260-ucode-25.17.12.0.tgz
Any suggestions of how to fix it it's very wellcome thanks
