Need up-to-date driver!

Hi,

I got the Windows 10 notification this evening and I was looking if my old laptop could run it and it seem yes, but I need to update some stuffs.

My laptop is an Inspiron N5010 (I will change it at the end of the year or next year) and it say that :

I have the latest version of these software (from Dell website), but I don't know if I can install some recent version of them from other website and which one...

I don't want to have Wifi and audio problems with Windows 10.

Thank you
