You need a remote to connect a Roku device (including a Roku TV) to a WiFi network. Since it's a Roku TV, it's hard to find universal remotes that work with them. Standard Roku device codes are on most universal remotes, but not Roku TVs. So, your best bet is a Roku Voice Remote. You can pick one up at Walmart, Best Buy, or similar places.
Well, you could if you were in the USA. Since you said "good afternoon" and it's night in the USA (well, not in Hawaii or parts of Alaska), there's a good chance you might not have Walmart or Best Buy nearby. So, whatever local retailer carries Roku accessories would be the quickest way to get up and running. Or, order one online. They're $20; the Voice Remote Pro is $30.
All Roku Voice Remote devices (standard and Pro models) work on all Roku TVs.
