Title:
IPv4 Address Lost 8 Days After Previous DHCP Allocation
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
My Ubuntu 16.04 desktop frequently loses the IPv4 address on its wired
ethernet connection to my office's network. This happened this
morning and previously happened 8 days ago.
The network uses a Windows Small Business Server as its main Active
Domain Domain Controller which includes a DHCP service. There are
several other Ubuntu 16.04 machines on the network that do not seem to
experience this issue. This is an IPv4 only network, no IPv6 services
are configures and IPv6 is disabled on most machines.
My PC has two wired network ports. One connects to the office network
and uses DHCP to get an IPv4 address. The other connects to a switch
on my desk that has test equipment connected to it and uses a static
IPv4 address.
I have the output from:
ll /var/lib/NetworkManager
nmcli -p c
nmcli -p c show TN\ Wired
Taken; after the renewal of the address eight days ago, this morning before I
"Disconnect"ed the connection from the drop down menu and after I reconnected
and an IPv4 address was re-acquired. If any of this would be helpful, please
let me know and I shall post it.
