Unable to connect iPhone's hotspot to Windows 8 PC

I'm using iPhone 6 and iOS 10. My laptop is Macbook Pro 13'' late 2011 but I installed Windows 8 on it. I have successfully connected to the hotspot from my laptop many times already but it just stopped working today. It said the connection is limited, and when I tried to access a web page, i said no internet connection. I then tried to connect to the hotspot from my iPad and it worked. I got connection. I restarted my laptop but it still didn't work. I turned off the Cellular network on my iPhone and then turned it back on, still no luck.

Solution

The solution is renaming my iPhone and restarting the hotspot. I renamed it by go to Settings > General > About > Name.
