Problem: Previously my OnePlus Smartphone was connecting to my Dell laptop using Mobile HotSpot. But after some time when I updated my mobile OS updates. My Hotspot was not displaying under the wireless network connections list.
Solution: I found that under Wi-Fi hotspot setting there was one property named AP Band, it has two options 2.4 GHz Band and 5.0 GHz Band. I was not able to connect over 5.0 GHz. so I changed it to 2.4 GHz and applied the changes. It started showing again in the wireless network connections list and I was able to connect it.
Hope it will help.
