Symmetric gigabit is great for DDoS botnet operators.

The aggregate bandwidth capacity of these networks exceeds 100 Tbps — more than most national internet backbones can absorb. And symmetric gigabit fiber rollouts keep making the math worse: average upstream bandwidth per compromised endpoint increased 75% year-over-year in North America.

Solaar appears to be available through the Fedora package manager. Among other reasons, using the package manager is preferred because it gives you a mechanism to remove it cleanly, including any system changes such as the udev rule

I’m not a Fedora user myself, but I suppose if you open the terminal and run

sudo dnf install solaar

This would install both solaar and the udev rule.
