Keyboard and mouse freeze up in Ubuntu 16.04 with 4.4.0-7 kernel

[William T. Lowther]

Keyboard is sporadically responsive before freezing. Mouse is twitchy before freezing.
Ubuntu 16.04 with 3.13.0-86 has no issues at all.

Issues started after upgrading to 16.04. The previous kernel that was in use was 3.13.0-86, which had no operating issues.
I have installed 4.12.0-0412004rc4-generic which is now in use. I cannot access the internet with cable, but can with wireless. The keyboard and mouse have not locked up as they did with 4.4.0-78, altho they do not operate smoothly. In terminal (and wireless), sudo apt-get update yields "Temporary failure resolving...". Pinging ubuntu.com and 8.8.8.8 results in "unknown host" and destination host unreachable", respectively.
