The general answer is that you log into your router and browse the settings. On some ISP-rented/controlled routers you may not be able to control them in the usual way and may have to use the ISP’s website or app to control it. I don’t think you have mentioned any router or ISP so it’s hard to be specific.
By the way, is your Roku working in general? Just checking the basics! 😀
Roku is working in general I just have it connected to wifi but I don’t know how to do all that stuff with the router and I don’t know what a isp is.
ISP: Internet Service Provider. It's whoever provides you with your Internet access. If you rent your router/modem from your ISP they retain the ability to make changes to any and all settings, including the security setting we are referring to. If you purchased your router/modem yourself, then they should not have access to those settings, unless you granted them access.
What should I do once I get to those settings i been trying to fix this for hours and still the device won’t show up anywhere
Without knowing your specific hardware (make/model), we can't offer specifics on where that setting might be located or even exactly how its labeled.
