Hello there @Members_qE7BXmI!
Along with the other troubleshooting that has been mentioned in this thread, I also have a couple of suggestions from a similar experience. First would be a wired connection to the router if possible. If that can't be done, you'll need to set your television as a priority device on your network. That's what I ended up doing and my television hasn't disconnected since!
If you need any additional assistance, don't hesitate to send us a DM!
