Failing to get ipv4 address from dhcp
One of the network I connect to on wifi offers both ipv6 & ipv4 addresses.
Getting an ipv4 almost always fails. NetworkManager appears to request an IP address with a previous lease, but the server for some reason rejects it.
My only fix to workaround this rejection is to remove all the lease files (/var/lib/NetworkManager/*.lease
), then the dhcp request succeeds.
