Joseph - after I reported this bug, I got so frustrated with the issues I was seeing that I rolled my installation back to 18.04LTS. I really don't want to screw up my system by inserting a kernel that may break a system that is known to work.
As was noted on the other ticket I have (bug 1799875), kernel 4.18 added some memory checks that which the NVIDIA driver supplied by Ubuntu is known to violat. This causes a kernel halt. Can you confirm that the 4.19 kernel will not break my working 18.04LTS installation? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1800316 Title: Loss of network connectivity Status in linux package in Ubuntu: Confirmed Bug description: On Ubuntu 18.10 I consistently lose network connectivity after some time. When trying to submit the but an hour ago I lost connectivity just prior to clicking submit. Runing "sudo /etc/init.d/network-manager restart" re-initalizaes the system, but I am still unable to ping or otherwise communicate with the wireless router at my home. My linux box is hard wired to the wireless router. I have been using Ubuntu for for approx 12years and never experienced this problem. The only solution is a reboot, but there are problems with that too.
