@ryecoaaron - I followed your directions and (still) have a running system. However, it appears that the onboard Broadcom NIC drivers for my Dell R410 are not in the linux-image and linux-headers you recommended be downloaded.
Before I completely and utterly kill my system by other means - I notice a large number of .udeb files in the http://us.archive.ubuntu.com/u…ol/main/l/linux-hwe-edge/ repository. Would installing say ... nic-modules-4.11.0-14-generic-di_4.11.0-14.20~16.04.1_amd64.udeb ... be a good idea?
I haven't hacked around with a kernel in almost 20 years and more of the nuance is gone from my brain. Any guidance would be spectacular I'll continue to google in the meantime and see what i can find...
Thank you!
