Wireless wifi driver for a Inspiron 13 7000

Hello! Folks im new here my nane is Juan and i am from Argentina. I bought a Dell Inspiron 13 7000 in a shop and they changed it twice because the laptop was not able to find mine or any wireless network around my area where my apartment.

So then i found out in the Devices Administrstion window that the laptops the shop were given to me had no wireless or wifi drivers installed from origin. I mean in the adaptators window inside the Device Administration were only two bluetooth drivers but no wireless ones.

Do you think that that is the problem why the laptop cannot find any wireless network around? (a list of them)

If that is the problem, could anyone tell me where i can get an updated wifi drivers? Because what i found on any Dell website that i entered from Argentina i could not find any suitable. The laptop rejects their installation.

Could you tell me the exact name for a Inspiron 13 7000.

Thanks a lot!

Juan
