DELL Latitude 3940 Network Issue

Hi,

I'm currently facing an issue with network connectivity for my laptop Latitude 3940. Intermittently getting disconnected. I tried to run SupportAssist to check for any driver update and updated all the provided updates from SupportAssist such a BIOS, graphics driver, touchpad, etc. 

But still, I'm getting the icon which indicates I'm not connected to my wifi. This occured to me trice already. What I do to resolve this is I go to the Network & Internet Settings -> Change Adapter -> Wi-fi, right-click, select Disable and right-click again Wi-fi and select Enable. After that, I'm able to connect to the internet again. 

Has anybody experienced this intermittent network connection issue?

Can anybody support me on this?
