(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.
