Looks that my internet connection is now stable even when downloading. I'm not sure what of the three things that I did fixed the problem but here what I did so that others can test further:
1. In the /usr/lib/pm-utils/power.d directory in the file wireless I changed in the end of the file with two off so that there is no wireless powersave: case $1 in true) wireless_powersave off ;; false) wireless_powersave off ;; *) exit $NA ;; esac 2. I also blacklisted wireless power management creating blacklist file : sudo nano /etc/pm/config.d/blacklist HOOK_BLACKLIST="wireless" 3. Third I installed wicd , without removing network manager , and with wicd I checked all other networks with "Never connect to this network" except mine network. So I don't have time to test further but downloading is working with better speed then before and is not interrupting anymore. Once again my configuration: linux mint 17 iwlwifi-7260-9.ucode 3.16.3-031603-generic linux-firmware 1.127.4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1354975 Title: iwlwifi Intel 7260 Wifi disconnects To manage notifications about this bug go to: https://bugs.launchpad.net/unitylinux/+bug/1354975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
