With this result it's hard to believe that you could "download a file successfully use wget".
Is DNS working? What do you get with cat /etc/resolv.conf? BTW, 'distro.ibiblio.org' appears to be 152.46.7.109, so you could try to replace 'distro.ibiblio.org' with '152.46.7.109' in '/opt/tce/mirror'.
just to be clear I did not download a file successfully from that address with wget, I downloaded a file from another website; I was just testing my internet connection.
I can successfully ping the IP you listed.
The result of the command cat /etc/resolv.conf returns the IP of my internet gateway.
BTW, thank you for taking the time to help.
UPDATE: Your suggestion of replacing the words with the IP worked successfully. I now get a listing from Appbrowser.
