There have been cases of routers which get into a state where they are sending corrupted beacons which the iwlwifi firmware rejects, which can lead to the types of disconnections I see in your logs. It's possible that this is what happened, and when you updated (and presumably rebooted) your router it cleared up the issue.
I'm closing the bug as invalid. If you see issues again you can reopen this bug. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1366248 Title: [Intel D54250WYK] Wireless Dropped Connection Intel 7260.HMWG To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1366248/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
