This is a duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=191601, which also contains a script that might be able to reset your card without a reboot.
Please see my longer comments here: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1673344. In summary, I believe this to be a longstanding hardware-software bug in Linux due to a hardware degraded 7260 NIC. Replacing the 7260 card fixed it for me. ** Bug watch added: Linux Kernel Bug Tracker #191601 https://bugzilla.kernel.org/show_bug.cgi?id=191601 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1736794 Title: iwlwifi driver for Intel 7260 crashing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1736794/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
