Home internet and Samsung TV keeps disconnecting

I know this thread is kind of old, but has this fix worked for anyone else? I have 1 Samsung tv that refuses to connect to my T-Mobile home internet. I tired resetting the network settings, factory reset, as well as creating a new network to match the above settings. The tv will not connect. I can get the TV to connect to my work phone hotspot and my T-Mobile phone hotspot ( both are iphones). Any help would be greatly greatly appreciated! The tv will connect to the router ( local network) but will not connect to the internet, I successfully connected the Blu-ray player to this new network as well as the regular T-Mobile internet I have (if that helps troubleshooting)
