Wireless Adapter issues

Hi

I'd appreciate any help.

I have a dell inspiron 15R SE 7520 laptop.  Recently  upgraded to windows 10. I'm having wireless network issues.

Under network and internet settings there is no longer any wireless settings. No option to turn the wireless adapter on. If I go to device manager under network adapters there is

• intel centrino wireless n-2230
• Realtek PCIe GBE family controller

It says both are running correctly.  I've uninstalled drivers and reinstalled the most up to date drivers but nothing.  I can access the internet through an Ethernet cable.

I'd appreciate any suggestions.  Apologies if this e-mail is a bit basic on details.  I have searched the internet for solutions.

Many thanks
