my pc is too old and it doesn't have wi fi, and the only wi fi line i can get in my house is in my garden...not the best..
If you can connect your PC via a LAN cable to a network that has wifi (not cell service, but wifi ) that your phone can connect to, you can. The PC does not need to have a wireless connection, just the phone.
edit - I have to say, it sounds odd to have wifi in your garden
