    I cant seem to connect to the Internet when I start the system. I can connect to the Internet when I boot into Recovery mode.
    It is not clear which instance the wireless script you posted represents. You have an IP address and pingable DNS nameservers. What is the result of:
    Code:
    ping -c3 192.168.42.1
    ping -c3 8.8.8.8
    ping -c3 www.ubuntu.com
    If the script you posted was not when the internet wasn't working, please shut down, cold start and run the script again so we may compare.

    Very interesting. Your first paste, when it works as expected, shows:
    Code:
    eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
            inet 192.168.42.75  netmask 255.255.255.0  broadcast 192.168.42.255
            inet6 fe80::e36c:887d:1fd5:6cd7  prefixlen 64  scopeid 0x20<link>
            ether <MAC address>  txqueuelen 1000  (Ethernet)
            RX packets 65438  bytes 94715718 (94.7 MB)
            RX errors 0  dropped 0  overruns 0  frame 0
            TX packets 34853  bytes 2562275 (2.5 MB)
            TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
            device interrupt 20  memory 0xfbf00000-fbf20000
    This IP address is consistent with an address given by a router. The 192.168.x.y series are reserved private addresses allocated to routers, switches and other access points.

    Here is the same information from the paste you just put up now:
    Code:
    eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
            inet 50.1.227.2  netmask 255.255.255.0  broadcast 50.1.227.255
            inet6 fe80::e36c:887d:1fd5:6cd7  prefixlen 64  scopeid 0x20<link>
            ether <MAC address>  txqueuelen 1000  (Ethernet)
            RX packets 8381  bytes 11787003 (11.7 MB)
            RX errors 0  dropped 0  overruns 0  frame 0
            TX packets 6582  bytes 591223 (591.2 KB)
            TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
            device interrupt 20  memory 0xfbf00000-fbf20000
    That appears to be a public IP address reserved and assigned by, I assume, your internet service provider (ISP). What explains that? What is the ethernet cable connected to? A router? What is the router connected to? Is the router defective? Is it connected correctly?

    I have static IP's from my ISP. I have used a router and I let the router assign IP's using DHCP.
    I really hate the idea of reinstalling 17.10 again.

    Nobody suggests that you reinstall.

    Your router surely isn't assigning a public IP address to your Ubuntu computer, is it? What is on the other side of the router? A cable or DSL modem or some such?

    I assume that the static IP from the ISP is the WAN address and therefore, shouldn't all the LAN addresses be 192.168.x.xx?

    Hi

    I have the Dell Machine plugged into the Modem directly on a Ethernet connection on the Dell.

    Above, you said you have used a router. But not now? I’m confused.

    Thank you for your effort. I am just going to reinstall it. I might go back to Ubuntu 16.04.03 Thanks anyway. I think.
