Just bought Grime Fighter, running on a wifi card, can't connect to internet

Hello, I recently bought grime fighter to optimize my PC for me. And when I try to run it it tells me grime fighter needs to connect to the internet, and I am connected but I have a usb wifi adapter for my desktop. I don’t have an Ethernet cable that is long enough to reach my router or modem. Does anyone know how i can fix this so I don’t have to get a refund?

Get a longer cable or move your systems closer to the modem/router.

Okay! Will go to bestbuy now to buy a 100 ft Ethernet cable lol. I’ll post how it goes.
