(dual boot: fedora-34 and windows-7; gnome)
Usually, I use my home workstation with a direct ethernet connection
to my modem. A yellow cable goes from the modem to the yellow
receptacle on the back of the tower.
Occasionally, I go through a router. The yellow cable goes from the
modem to the yellow receptacle on the back of the router, and a blue
cable goes from any of 4 black receptacles on the back of the router
to the yellow receptacle on the back of the tower. This has worked
fine for a few years now: for the tower (both Fedora and windows) and
for my ipad.
But now it does not work: not for Fedora, not for windows, not for the
ipad. Fedora shows no connection; I've found no way of diagnosing the
problem. The ipad seems to sense the wifi signal, but there's no hint
of data (all attempts to use the internet time out); I don't know of
any way of diagnosing the problem. In windows, the indicator shows no
internet connection; its diagnostic tool says something about "teredo"
being disabled? deactivated? by the sysadmin.
Using the router last worked in mid August (fedora-33 on my
workstation). I did not attempt to use it between then and this past
Wednesday.
The upgrade from f-33 to f-34 occurred between the last time I
successfully used the router and the first time it didn't work. Is
that just a coincidence, or did the upgrade have something to do with
it? How do I get my workstation, ipad, and the router working?
For the f-33 to f-34 upgrade, the tower was connected directly to the
modem; the router wasn't even powered up. But might f-34 have done
something to the router when I connected them? The router is a D-Link
AC1200; it's between 3 and 4 years old.
Did you power cycle the modem after making the wiring changes?
My ADSL modem auto-configures itself when powered up. If I make changes
to the wiring a power-off/on is required for
them to take effect.
I would, power-cycle the modem. Waiting sufficient time for it to come
up. Mine has a red LED that will go out when it
becomes ready. Then restart the D-Link. Waiting again. And then
down/up the network on the Fedora system.
That appears to have worked. (Odd, I never had to do that before.)
This reply is going through the router. The ipad is currently upgrading
its os through the router. If after a while, everything is still good,
I'll close this thread.
Thank-you, Ed.
