Who is your ISP (internet service provider) and what is the router model number?
What do you mean exactly, "switched networks"? Do you mean you switched ISP providers, routers, changed from the 2.4ghz band to 5ghz band, or do you have multiple networks in your home?
Go to Settings/Network/About in your Roku. Under the MAC address and the IP address, are either one of these showing all zeros (0)? No need to report the actual numbers showing, just verify they are not zeros.
If you have access to a mobile hotspot, can you connect your RokuTV to that and get an internet connection?
Feel free to post back with responses to the above as best/detailed as possible as well as any error messages you are seeing on screen.
Thank you for your reply. My internet IS a hotspot and yesterday I switched to a different one. Same brand, and it works fine on every other device in my house. Well, it took a lot of wrangling with google home to get it to finally work on the other TV, an LG, but at least it had an internet connection all through the process. The Roku TV has never been any trouble until I switched hotspots. As I mentioned, it will show the network on the list and will show the wireless connection with a green check, but the internet connection cannot be made. I have unplugged everything many times, reset the chromecast each time, and even left them all unplugged for 30 minutes but nothing changed. (I can't figure out how to put the photos in order, but I hope you get the idea.) Thank you for your time
There is an issue with how the Franklin T9 and T10 hotspot devices are handling their IPv4/IPv6 protocols (this is how they connect to the internet) and the Roku devices. On some on these hotspot devices, they are actually set to use IPv6-only by default.
Roku needs to have IPv4 capability enabled in the hotspot device. You can try enabling IPv4/IPv6 initially. If that doesn't work, then select IPv4-only and you should be good to go.
Basically, you just have to clone your existing APN (the Access Point Network) of your hotspot device either by logging in at TMobile or using your TMobile app. Essentially, just clone (create new APN and copy all the info for your existing APN fast.com) and keep all the settings the same, but change the "IPType" to either IPv4/IPv6 or IPv4 and then set this new APN as your default.
Below are the instructions for configuring the new APN. Restart both the hotspot device and your RokuTV after making the below changes.
-----
Instructions for changing APN can be found here. (https://www.t-mobile.com/support/devices/t-mobile-hotspot)
Look specifically under "Connections and Network", then expand "Network and APN".
Login to the WebGui and follow these instructions. Basically you need to verify IPv4 is selected after creating a new APN name.
Create a new APN (Access Point Name)
Your mobile hotspot comes pre-configured with the access point name (APN) for your network service provider. The mobile hotspot checks the APN to determine the type of network connection to establish.
Access the hotspot WebUI Manager.
Click Settings > Network Settings.
Click the Add button under the APN list. A pop-up box will appear to create new APN.
Enter the Profile Name of APN.
Enter the APN.
Enter the Username and Password.
Select Authentication Mode: PAP or CHAP.
Select IPType: IPv4 or IPv4v6.

Feel free to post an update or if you need more help.
Thanks again. The hotspot is identical to the one it replaced, but I'll see what I can change. It's a library owned device so I'll need their permission first.
Also, it works just fine on the other TV and on all computers in the house but I will look into this.
Thanks again, I'll let you know how this turns out.
interesting edit: I am able to chromecast to the Roku TV from my laptop, so it seems to have wifi for that. I don't get it...Thanks again
Chromecast allows the user to cast with, or without, an internet connection.
All you need for a Chromecast to work is a wifi (network) connection. You do not need internet. Internet access will allow you to cast online content via the Chromecast to a connected device/TV. Without internet, you can still cast local file storage (files on your computer or local media server) via the Chromecast over your wifi (network) to the connected device/TV.
Therefore, you are merely casting to the Chromecast (that is connected via HDMI) to your RokuTV. The RokuTV does not even have to be connected to your network in this scenario because the Chromecast is delivering its content via the HDMI connection.
EDIT-- after re-reading your post, not sure if you mean a Chromecast device (above info then applies), or if you mean the Cast feature from within Chrome on a laptop (if so, then it is via wifi/network connection). Regardless, the internet does not figure into it in these scenarios on the RokuTV side of things. During casting, the RokuTV does not have to be connected to the internet to "receive" the casted content. Just has to be connected to the same wifi (network) if the latter scenario.
