Public bug reported:
If a connection to a router is lost while you have active ethernet
connections to hosts (on the Internet), networking can't be resumed
before all connections are closed. Many software packages repeatedly try
to resume their lost connections, which must lead to a human
intervention to quit all software before the connection to the router is
re-established.
Seems as it is the kernel that prevents connections to the router, by
holding lost connections.
Even if you in disable networking by selecting "Enable Networking" from
the drop down menu, and re-enable it, you can't get through to the
router before all user software has quit and closed all connections
holding the lost host connections.
This bug has existed for a long time(=years), but I have never learnt
what the error could be.
