From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If you set a static ip can you get connectivity? Have you confirmed that your interface is still up via Ifconfig or ip link?
I wouldn't know how to do that. Would I have to find out what specific IP to set it to, or would any random one work?
It has to be in the same subnet as your router.
You need an IP that is in the same subnet as the rest of the network. Take your gateway IP and then find the subnet mask. (It is probably a /24 which is 255.255.255.0)
Next pick a random ending number (x.x.x.67 for example). Try to ping it from a different device to make sure that it isn't in use. Once you do that you can set it on the server. Go to network and then set it to manual. Set the IP, subnet mask and gateway IP. Then try to ping the gateway. If that fails you have a layer 1 problem (hardware)
I set the manual ipv4 to 192.168.0.72, and it says it's connected - it doesn't have any 'activation of network connection failed' error messages, but it doesn't seem to actually have any internet either
That's good. What's your routers IP address?
62.49.7.152 is my public IP, if that's what you mean. How do I use that information, other than allowing others to know my approximate location?
I'm looking for the private IP. (The one your router has on the inside network)
How do I find that? Is it written on the router somewhere, or is there a command to run to find it?
How did you set it up? Did you just plug it in and forget about it?
I didn't set it up; another member of my household did
Oh
Is your phone connected to WiFi? What do the network settings show on your phone?
Did you want a specific part of network settings, or is this helpful?
Set your gateway to 192.168.1.1. Can you then ping 1.1.1.1?
Here are the network settings
I tried changing the IP in manual settings, I'm not sure how I ping an IP, I assume it's a command that I don't know, but as the screenshots show, accessing a website didn't work. I saw an IP in the startup menu and tried that but it didn't seem to work
Your netmask should be 255.255.255.0
Why is that? I applied the change, and restarted the Ethernet connection, but I still don't have internet
You have a upstream issue then. I would start by checking the physical port and then work your way up until you find the fault.
It is also possible you have a bad network card as this is older hardware
I tried what I said, reinstalling to see if it still had internet. It did not. Therefore I went into a rabbithole of trying to rule out specific things of why it was working then but not now, and I still have no idea why it was working then, but I have plugged the Ethernet powerline into a new, more inconvenient, plug socket, and the wired internet is mostly working! I can still access most sites, but Firefox won't connect to addons.mozilla.com or accounts.firefox.com. Idk if that's a Firefox issues or a network issue, but it's mostly working now, which is great!
Hmm. One way to check multiple options at once is to try the install again and see it internet is still present when installing the OS, as it was before. If it is, that would rule out a hardware issue.
