Why is my Internet connection not connecting?

I am using a Dell tower desktop with an XP operating system. I use it mostly to run several programs to write and print simple things, as well as some pretty elementary stuff. As you may imagine, it works just fine for such things.

I also had in hooked up to the Internet for very limited, infrequent use and again, no problems.

Now I am rearranging some things and have moved the computer to another area in the same room, with everything the same except for the addition of a new monitor. I did have to use an older connection to get the monitor  video into the computer, but no problem.

BUT when I plugged my Internet cable into the  SAME router, I could not get an Internet connection (using Google Fiber). Tried a second cable with the same result.

I can't figure this out. Surely a new monitor is not to blame for this situation?

A monitor cannot be a cause for network problems. Have you trying to turn off the network controller in Settings and then turning it on for reinitialize? In XP you could right click on Network and got to network settings and there disable and enable your network controller.
Plus go to router settings and check if it sees the connected interface at all.

open an elevated command prompt and type :     ipconfig
post a screenshot of what it says
check also if your network card is installed correct in device manager (if it' a desktop - the card may have come loose - remove and reseat it)

I have been having an absolutely horrible time with this problem.

Network settings simply does not display anything and a search on "router" returns no results.

The results of the elevated command prompt "cmd"  suggestion does not return cmd.exe

And I had a local computer service fellow from Office Depot here for two hours today who could not get the computer to get on the network. My requirement for hiring him was that he be proficient in XP, which he was, but nothing worked.

I have an installation package for WIndow 7 in my collection of "maybe useful someday" stuff. Is it time for me to get it out and run it? And if so, what do I need to be aware of as far as the files, data, and programs that are all intact and running (as long as I do not need to be online) on this XP machine?

If this is a windows xp machine it must be quite old. You will have to know whether windows 7 will install on your system, it has to meet specific hardware criteria in order for you to install windows 7.  From the Microsoft website here is the minimal criteria to install windows 7, note this is minimal, it will run on the following but it will be slow, should have a better CPU and more ram and a good video card.

If you want to run Windows 7 on your PC, here's what it takes:
1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor*
1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
16 GB available hard disk space (32-bit) or 20 GB (64-bit)
DirectX 9 graphics device with WDDM 1.0 or higher driver.

It could be that your network interface is simply dead. Can you get a PCI network card or USB WIFI dongle and see if that works?

noxcho, on the suggestion of the tech who was here today, I went out and bought a USB WIFI dongle that was the last one in stock for an XP computer system. The little CD that came with it for installation was recognized but the installation software on it would not work.

Well I am still sure that ethernet adapter is malfunctioning  in your case and it can be replaced with some old pci ethernet card.
Something like this: https://www.amazon.com/TP-Link-TG-3468-Gigabit-Ethernet-PCI-Express/dp/B003CFATNI
Check on ebay for some old spare parts.
Or this one: https://www.amazon.com/TP-Link-1000Mbps-Gigabit-Ethernet-supported/dp/B003CFATNI/ref=sr_1_6?keywords=Pci+Ethernet+adapter+windows+xp&qid=1567754703&s=gateway&sr=8-6

To all experts: thank you for your suggestions and help. In light of the comments here and talking with some engineer friends, all the info I've received over these last few days seems to point to a direct solution that will have to be implemented sooner or later regardless of what I'd like to do--and that solution is to upgrade to a new computer.

And, thanks to a sizable and rather timely, unexpected influx of payments for web ads, that came in this week I can simply pick what I want/need off the shelf and take it from there.

But don't worry....I know from past experience I'll be calling on you again. Computer functions seem to have a way of creating unexpected questions often enough to need expert consultation.

Strangely the accepted solution is not relevant to your original question. Thus if anyone searches for similar problem and gets to this discussion he would go disappointed.
