Wired networking down. Fedora 37. [SOLVED]

You can delete this if you want to,

nmcli con del mylan

It is a lot more stable now, and I'm sure the uuid works fine now, but old habits die hard.
Trying other things....

If they aren't already installed, you can try installing dig or nslookup.

dig linux.org

nslookup getfedora.org


The output of these, can help troubleshoot your DNS.
You can see what nameservers you are using, if they are actually resolving and if they
are forwarding the correct IPs.

Looking at "ip addr" I see that the ip for enp11s0 is 192.168.0.34. When I first started trying to figure out what was wrong, I assigned that along with a gateway of 192.168.1.1 for the Asus router. The ...0.34 was a wild guess. Maybe that is causing problems? Just my 2 cents worth.
 
(Please excuse my rambling on if it is a distraction)
I note that I do not have any configuration files in /etc/NetworkManager/conf.d. I do have a file that I am told not to edit that is
/etc/NetworkManager/NetworkManager.conf
Could there be a missing file in the conf.d subdir? thanks
 
Here is a question: Why does this show a transmit and receive of 332k and 222k bytes, respectively?
~> ip -s -h l show dev enp11s0
2: enp11s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000

RX: bytes packets errors dropped missed mcast
222k 932 0 3 0 508
TX: bytes packets errors dropped carrier collsns

Sorry, I'm at my real job today, so I've been back and forth a lot today.

Lets back up a little.
I see that the ip for enp11s0 is 192.168.0.34. When I first started trying to figure out what was wrong, I assigned that along with a gateway of 192.168.1.1 for the Asus router. The ...0.34 was a wild guess. Maybe that is causing problems? Just my 2 cents worth.

The computer and the gateway have to be on the same subnet. The IP addresses don't matter as much as the
subnet mask does.

The 192. and the 168. are the same on both subnets, so we can ignore them for now.
Your NIC has a 0 in the 3rd octet, your router has 1 in the 3rd octet. So that's a difference.

Do you really want these to be different? It's OK if for some reason you need them to be.
"Usually" (but not always) "most" (but not all) home networks are on a single 24 bit subnet.
You can check this by looking at your subnet mask. It'll "usually" be 255.255.255.0
In this case, that won't work for your network because of the 3rd octet.

Thanks. No that was a screwup on my part. How do I change it to 192.168.1.x?
 
Having a full blown network class here might not work :)
For now it would be easier if your NIC and your router were both in the same subnet.
For example. Your router could be 192.168.1.1
Your NIC could be 192.168.1.34. The first 3 numbers are the same.
Normally routers are set to .1 but they don't have to be. It's just a convention more than anything.
The other IPs on that subnet can be anything except 0 or 255. It can't be 1 because your router is
already using it. But it could be any other number between 2 and 254. At least as long as nothing else
is using that address. Your cell phone and any printers could have an IP on that subnet as well.

nmcli con mod 'Wired Connection' ip4 192.168.1.34/24 gw4 192.168.1.1 autoconnect yes ipv4.method manual
 
That was it!! I was just about to give up and erase the disk and start over. You saved me, Dos2Unix.
It looks like it is workign now (after a reboot)
I hope I can repay the favor one day.
And once again, thanks for your patience.

Nice work, the pair of you :)

@Atheist if that fix persists, you could go to your first Post #1 and edit the title to include

[SOLVED] at the beginning or end.

Cheers

Wizard

BTW good time for a Timeshift snapshot if EXT4 or Snapper if BTRFS?
