Laptop WiFi looses connection

Hello:

I use my Smartphone as a Hotspot, I have me Dell laptop set-up to connect to the Smartphone "Hotspot" and for several months I had no problems using the internet with this set-up. But in the last month, the few times I have worked with this set-up the Dell laptop intermittently looses the connection I have to keep going into the laptop settings to reconnect.

The Smartphone "Hotspot" remains on throughout.

Can anyone let me know what might be going on with the laptop, that wasn't before.
