LiveCD not registering Ethernet connection

I’m not 100% sure where to put this post, so if I’m in the wrong part of the forum, please let me know and I will be quick to move it.

I’m trying to install Arch Linux on my laptop. I’ve installed Arch several times before, many of which have been on this same computer, and they all worked perfectly, connecting either to the Ethernet (or Wifi when Ethernet wasn’t available) flawlessly and without complaint. This time it seems to be different. Connecting to Wifi appears to be successful, Iwctl never throws any errors, yet utilities like pacman can never seem to download anything. Ethernet is even more puzzling. While connected, the connection indicator comes on, and the activity indicator flashes in an irregular pattern that seems to indicate that there is data being transmitted. Trying to use the ping utility results in it hanging for around 5 seconds, before throwing this error:

ping: www.google.com: Name or service not known

Which seems to indicate that it is connected in some way, otherwise it would throw this error:

 ping: www.google.com: Temporary failure in name resolution

The only difference between this setup and the old one that worked is that I’m trying to connect to a Wireless Access Point, specifically a Netgear PLW1000v2. Trying to bypass it and connect to the main Wifi is possible, however it contains Unicode characters not recognised by the terminal. Any ideas what I’m messing up to cause this problem?

Re: LiveCD not registering Ethernet connection

Can you "ping 8.8.8.8"?
What's the output of "resolvectl status"?

Output of “ping 8.8.8.8”:

Re: LiveCD not registering Ethernet connection

Please use [code][/code] tags. Edit your post in this regard.

ping: connect: Network is unreachable

So it's not a DNS issue, there's no network connection at all.

ip a
ethtool eno1 # idk whether the install iso provides ethtool
