I have a Realtec 8139 NIC that works fine with RedHat 7.3. It detects my cable connection with dhcp enabled without issue. When I upgraded to 8.0 the NIC will no longer activate. I've used lokkit and the network security tool to reset the iptables and verified settings, enabled dhcp at startup along with the auto dectect option without success? I've reinstalled the NIC, even manually configured dns entries. I went back to 7.3 and again no issues? Someone please help this newby out of the woods! hahaha :x
