Hi @Staceface89 and also wanted to extend a welcome to the Roku Community.
It sounds like the TV's connection to your Wi-Fi network is causing a bunch of frustrating issues. To narrow down the issue, are you able to plug in an Ethernet cable temporarily from the TV directly to the router?
Using an Ethernet cable, you'll want to set your Network to "Wired" under your settings menu. Then, try streaming for a few days, and most of the issues go away, you can assume the Wi-Fi is the culprit, and make some changes to your wireless network to try to help the TV connect better. You may find the 2.4 GHz network, for example, is better to use for your environment and this usually just involves switching the network during wireless setup, or potentially making a configuration change to your wireless router.
Try running a cable first, if you can, and let us know what you find. We'll be awaiting your results!
