In this video, I walk you through why Mobile Hotspot can randomly stop working on Windows 11 in 2026—and what I check first when it won’t turn on, devices can’t connect, or the internet just won’t share. I keep it simple: no fluff, just the common causes that actually break hotspot sharing, like outdated or buggy network drivers, adapter configuration issues, and Windows services that get disabled or stuck after updates. I also explain how Windows 11 handles internet sharing behind the scenes, because once you understand that, the fixes make more sense. Things like firewall/security conflicts, Wi‑Fi hardware limitations, and basic network configuration errors can all block hotspot from working even when your PC looks “connected.” By the end, you’ll know the safest troubleshooting path to narrow it down fast, so you’re not randomly toggling settings and hoping it works.
