Wifi fail after installation

I know I’m not answering to your question. Sorry but, why Fedora 25? You know that it is no more updated and so on?

@sqrt3,

You are welcome here – it is the Fedora Community and we are always excited to see new people. Can we recommend that you install Fedora-32? Yes, you are 7-releases behind. The newer releases are waaaaaay better and more likely to understand your machine. Is it an old box? In any case … You may be better off with this one.

old software usually require less memory/disk
many people use them for many reason
that’s why archive.fedoraproject.org is up and running

fedora 24 has same problem

Even if we ignore security issues, the problem is that virtually no one uses obsolete releases.
Thus, the possibility of getting effective support becomes very unlikely.

nmcli radio all; nmcli device; \
lspci | grep -i -e ethernet -e wireless -e net \
| while read -r DEV_ID SKIP; \
do lspci -k -n -n -s ${DEV_ID}; done

Try disabling MAC address randomization. On older software I notice it causes problems.

Open

/etc/NetworkManager/NetworkManager.conf

In your favorite text editor, like nano, and you should see a line that looks like this:

[device]
wifi.scan-rand-mac-address=yes

Change the yes to a no and then save the file. Finally run

systemctl restart NetworkManager.service

See if that helps. I’m not going to say outdated drivers since the USB worked, and there’s no way I can find modern drivers for software that old even if that was the issue.

Edit: If memory is a concern for you and that is why you are installing ancient software there are a variety of ways you can get a modern Fedora release or another distro to run with less memory. I won’t go into detail here but consider opening a thread on the subject. You can title it “running Fedora with low memory” or “Fedora minimalism” for example. :slight_smile:

Thanks!
NetworkManager.conf for fedora 24 and 25 doesn’t have device section

Thank vgaetera:

I think we should not troubleshoot unsupported releases at all.

Check this way:
