I bought a new Dell computer with Windows 10 (core i7, fast processing speeds, Large RAM and Hard drive) and it turns out it does not have (or recognise somehow) wireless signals. When I try to troubleshoot the problem is says that no ethernet cable is plugged in (i.e. it automatically assumes that the only way to connect to the internet is through an ethernet cable). I tried all the instructions online and nothing has worked.
For example, when I go to Network and setting and then network connections (from the side bar) many online forums say to turn off the ethernet and the wifi and then turn on the wifi only. The problem with my computer is that I only see an ethernet option.
Something else I noticed is that it says "Your PC or mobile device doesn't support Miracast, so it can't project wirelessly" Not sure if this has anything to do with the lack of Wifi connection.
I am actually quite shocked that I would pay so much for a computer that cannot connect to the Internet via Wifi.
In any case, if said problem cannot be fixed what is it that I have to purchase to establish a wireless connection from my desktop computer to my modem/router. I was looking at wireless USB adapters, is this the correct hardware?
I would really appreciate any help as this computer is for business purposes.
P.s. : Let me know if you need more details.
