For your name resolution reported issue on terminal (console), please check the content of the file /etc/resolv.conf
If it's empty, then for a temporary fix just add the following entry, substitute DNS_IP with your actual Nameserver (router GateWay IP or ISP provided Nameserver IP(s)):
Test the name resolution afterwards on console with, for example:
Code:
nslookup www.slackware.com
I'm not using NetworkManager myself and cannot really help you with it, but this link might provide some help:
