Important Linux Limitations

• Secure Boot: You must sign the kernel module or disable Secure Boot in your BIOS, as the driver is not signed by a trusted CA.
• Kernel Updates: Every time you update your Linux kernel, you must re-run sudo dkms install or ensure the DKMS script is correctly linked.
• Monitor Mode: The 8188GU driver supports monitor mode and packet injection (tested with airmon-ng), but performance is poor on channels above 11.

• Pros: Community-maintained drivers (e.g., rtl8xxxu or vendor modules) can work; basic connectivity achievable on many distributions.
• Cons: Out-of-tree or older Realtek drivers often needed; may require manual compilation, DKMS setup, firmware blobs, or kernel module tweaks; power management and stability issues reported by users. Not recommended if you need plug-and-play on Linux without tinkering.

For Fedora / RHEL

Use the same GitHub source, but you will need dnf groupinstall "Development Tools" and kernel-devel instead of build-essential. Secure Boot: You must sign the kernel module
