I had a similar problem just yesterday. Could not remember what all I
did to it in the past year, I do know I had majorly modified the
networking. I completely redid the network configs but still had the
ip address going back to the previous setup. Gave up on it and wiped
the hard drive and reinstalled Debian 12. Now everything works great.
It may come to that. Hate to do it, there are some old bits that I've
been using to interact with some specialized hardware - it's the whole
reason why I keep this 14-yo machine. I can *probably* reconstruct
but there's a finite probability that I'll miss something that I
didn't backup. Without a network connection it all gets harder.
It seems likely that there's some detritus from one or more prior
versions of Debian that's screwing things up, but I'm not
knowledgeable enough to figure it out.
This morning's reboot - networking reports via ifconfig and nmcli look
better (right IP#, gateway, /etc/resolv.conf set properly once I use
nmcli to force the device to connect, but can't ping the gateway nor
does pinging this system from other host get any reply.
Thanks to everyone for your suggestions!! I'll make a few more
attempts before the total rebuild but I'm not optimistic.
Classic route error. NM's favorite error.
look at "ip r", anything in the 169.xxx.yyy.zzz needs to go. I put all
my stuff at 192.168,yyy.zzz and remove avahi. & cups-browsed That block
of 65535 addresses does not get thru the router w/o a NAT entry in the
router, and generally just works. Even my 3d printers running klipper
are able to browse the internet. Keeping them uptodate can be done from
their own keyboard or an ssh link from this main machine.
