(sent from Thunderbird running in windows-7)
From Fedora-35, I cannot reach the internet at all.
- Firefox and Thunderbird each take several minutes trying before notifying me of time-out.
- If, as root, I do "dnf info firefox", it takes several minutes trying before giving me curl errors. So here too, apparently no internet access.
- In the corner of the display (gnome), there's usually a little fork-like symbol next to the little symbol that I click to log off or shutdown. That symbol is not showing.
- Firefox is able to communicate with the modem. I did not see anything in the modem's display in Firefox that looked like a problem.
- An rkhunter scan shows no problems, but I realize that doesn't check everything.
- Last night, I was in a 3-way zoom meeting on this work station (using Fedora-35 and Firefox) for almost 2 hours as a participant (not host). Immediately after that meeting ended, I shut down for the night. I noticed in the past that after a zoom meeting, some things do seem to be messed up in Fedora; I don't recall any details. I've been simply rebooting to solve that. Zoom does seem somehow "dirty".
- This is a dual-boot workstation. When booted up in windows-7 (like now), I am able to connect to some sites in Firefox, but not all. Some that I can connect to are unusually slow. Thunderbird also works, but is unusually slow.
The modem is an Arris T25 SURFboard, DOCSIS 3.1 for xfinity internet and voice. I originally thought the problem was the modem, but since it seems to be working when I boot into windows-7, I now think the problem is more likely to be in Fedora.
I have no formal training or experience in sys.admin.
