I installed Fedora 30 as a first-time user on my Sony Vaio SXF1521K6E from a USB stick. I then understood that I needed to install rpmfusion-free and/or rpmfusion-nonfree (from USB stick) for Fedora to detect my Broadcom BCM43142 and/or Tp-link USB so as to get wireless. On double-clicking either rpm file I received the message file not supported (within Software). So, I tried from within Terminal as a root user, but the rpms wouldn’t install unless I disabled other repo files, namely; fedora-modular, fedora-updates, updates and fedora. After “successful” installation I added and enabled as stated here^ but neither my pci nor usb (both for wireless) were detected afterwards (even on reboot). Before (with no disabled repos) I did try zchunk=false though it was not in my dnf-conf file. I also tried the zchunk patch anyway (had to disable aforementioned repos) but to no avail. ifconfig reports that both Broadcom and Tp-link are UP; iwconfig reports no wireless extensions for the Broadcom pci. With the repos disabled I cannot install DraftSight, with the repos enabled I get the file not supported fail message.
Here’s hoping that some can help!
P.S. This is from a fresh installation with nothing else installed (and re-installed x3)
