Mouse touchpad not working and loss of internet connection

Hi I was hoping someone here could maybe give me some insight to a problem that has just occured. Earlier today I was using my laptop and there wasn't any problems at all, but I have returned to the laptop now and find that the cursor is not responding to anything I do on the mousepad.

I also noticed that the symbol for internet connection is showing as if it has never been connected, with a red cross through it. I restarted the laptop in safe mode to see if this helped, and the cursor responded to my actions using the mousepad, however when I restarted the computer, this time in its normal state, the same problem reoccured.

Really hoping someone can give me some insight to the problem and a possible solution, first time this has happened

On my Dell laptop, there is a key-combo that turns the mouse pad on and off.
(Fn + F5)

I can also turn the wireless radio on and off via a switch on the side of the laptop. Some laptops use keys for that, others use software and some have no easy way to turn off the wireless radio.

Thank you so much, you are a saviour!

Glad that it worked for you
