How to fix desktop not connecting to internet with adapter

[Therebel10]

Hello I have just purchased a new avatar gaming computer but when I booted it up I could not connect so I plugged in a wireless adapter and it still won't connect I have tried looking it up but I can't find the answer I'm going out tomorrow to buy a new router and wireless adapter at bestbuy so if I could get a fix I would be a happy man
