I wanted to confirm that I was suffering of this bug, but reverting to the -7 (22.1.7.0) firmware solved the issue for me on AC 7260.
When I was experiencing the problem the firmware in use was 22.24.8.0, and my dmesg reported what reported in message #8 above. Turning off power save did not make any difference. My AP is a Netgear DGN 3500 on channel 11, 2.4 GHz, configured with "Up to 300 Mbps" mode, so 802.11n. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293569 Title: iwlwifi-7260-8.ucode causes network disconnections problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1293569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
