Bug Description
Description: A few times an hour the networking drops for around 20 seconds. It then automatically reconnects. The only clearly related message in journalctl is the DHCPREQUEST / DCHPACK followed the messages:
Starting Network Manager Script Dispatcher Service...
bound to X.X.X.X -- renewal in 1692 seconds.
[system] Successfully activated service 'org.freedeskto
Started Network Manager Script Dispatcher Service.
req:1 'dhcp4-change' [wlp2s0]: new request (1 scripts)
req:1 'dhcp4-change' [wlp2s0]: start running ordered scripts...
That makes me think that Network Manager silently died and was restarted.
Notes:
* The system is a new Dell Precision 5520 with a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
* This system started as a clean install of Ubuntu 18.04 Beta on March 31, 2018
* The wireless networking was stable from install until a system update on April 27, 2018
* The wired networking is completely stable.
