trying to make use of an old xp computer

[jacobixxx8]

i'm using and old XP system computer,it's hooked up from my
w-10 computer with an ethernet cable and also with wi fi
It shows that I'm conected to the internet but only some things
will come in it seems the things that were downloaded years ago
on there mostly work. I can use internet eaplorer and go to Fox News.
But when I try to download something that's not already in the XP
It says I'm not on the internet.

In Windows  XP you can use the ipconfig command at the command prompt.
It will tel you how you are contented.

Ipconfig is a DOS utility that can be used from MS-DOS and the Windows command line to display the network settings currently assigned and given by a network. This command can be utilized to verify a network connection as well as to verify your network settings.

Please try it and tell what your see.

Thanks for the ideas.
It does give me the address of mi IP and my address.
But what can that teach me to do? It probably tells me I'm on the internet
but why only on some sites? I'm trying to learn.
