But her Wi-Fi was now slower than a carrier pigeon, dropping packets like autumn leaves. firmware failed to load iwl-debug-yoyo.bin
Updating the kernel resolves this by providing The most common cause of firmware issues is
The system tries to load it, can't find it, and throws a "failed to load" warning. How to Fix It Maya had seen this before
