So I tried all three of those sysctl's and the problem is still manifesting itself (every 10 minutes, Network Mananger pops up a disconnected/reconnected message.
Moreover, I'll not that this problem does NOT exist in 14.04 (tested with the same hardware, same wifi+ethernet, using a 14.04.5 LiveISO, which uses the Xenial kernel (very close to the kernel I'm running here on 16.04). I really believe this problem is likely in Network Manager itself. I'm reopening that task for now. ** Changed in: network-manager (Ubuntu) Status: Invalid => New ** Changed in: network-manager (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1664748 Title: wifi connection drops, reconnects every 10 minutes Status in maas package in Ubuntu: Invalid Status in network-manager package in Ubuntu: New Bug description: I recently moved my home DHCP and DNS server over to MAAS (2.1.3 from xenial-updates). Since doing so, I've noticed that my wifi connection drops and reconnects (with corresponding Unity pop-up notifications) exactly every 10 minutes. I suppose this is due to the fact that MAAS sets DHCP leases to 10 minutes by default? Has anyone else noticed this behavior? Is there a suitable workaround? Increasing the DHCP lease time? Using static addresses? Something else?
