Guys, I have a HP with Fedora 28. The wifi diver never worked (realtek issue). But thats fine. I've solve with an usb wifi adapter.

Te problem is that since last week the usb ports just disappear when Im using the system. Everything is fine then suddelny thw wifi dicconects. The usb adapter is no longer identified by the system. The same happens with all usb flash disk. They disappear. I have to restart the system to have then back. Sometimes is not enought. Then I have to restart several times to get then work. Downloading a new fedora iso and making a fresh install does not solve the problem.

Any ideas?

This is the lsusb:

It might be simpler to try to make your Realtek card to work by adapting: https://ubuntuforums.org/showthread.p... to Fedora?

Some people have it fixed, by modifying the driver to not mcu_recalibrate: mrgromov comment on 17 dec 2017 https://github.com/kuba-moo/mt7601u/i... would need to be adapted to Fedora I guess, and then, it might not work for you...

more likely to work if you have the red-black no name USB stick.

You could check if the Linux kernel give some errors by typing:

dmesg

in a terminal.
