My Lenovo laptop won't connect to my iphone 5S hotspot anymore

I have been using my iPhone 5s hotspot everyday until today on my laptop. Under the network list, it shows that it is connected to my iphone, but if i hover my mouse pointer over the wifi icon on the taskbar, it says "Unidentified network No internet access." And my iphone does not say i have a connection like it usually says when my laptop connects. I have a good signal. I tried restarting my computer but it did not do anything different. Please help.
