@Courtney4747 most likely cause is a marginal wifi connection. To stream TV you need around 20Mb/s to stream in HD if you have a Netflix account you can check the speed while connected by running the network test in the Netflix app's Get Help menu.
However just as importnat as bandwidth is regularity and if tge wifi signal is weak due to thedistance from your hub the signal is vulnerable to interference from your neighbour's wifi and from your own electrical kit. In both cases you need a better connection to the hub. Ideally thst would be an Ethernet cable but that is often not a practical solution. A good second best is powerline adapters which use the mains cabelling to carry the data - you buy these in kits of 2 and they are pretty simple to set up.
Lastly is some form of wifi booster or whole home wifi solution but these can get expensive so if the TV is your only problem device powrrline maybe a better solution.
