Ubuntu Mate 16.10, 17.10 Wireless problem

I have tried both to install both 16.10 and 17.10 and have found that neither will bring up wireless networking on either my Dell XPS 13 (with Ubuntu 16.04 installed and working) or on my MacBook 13" from 2010. Since wifi is my only available connection, I am unable to access the Internet to look for possible updates. Anyone else having similar problems? What is the fix?
