I have a TCL 55US5800 Roku TV which is about 10 years old now. Since I got a new WIFI 6 router earlier this year, this TV has a consistent problem where it will appear to be connected to our network, then once we open a streaming app it will start playing for 10-20 seconds before the network drops and I have to exit to the main settings menu to reconnect. It will "connect" again like normal, then when I go back into an app the same thing will happen. It will eventually stay connected, but sometimes I only need to do this a couple times, while other times this might be a 10+ minute process of opening an app, start playing, exit to reconnect, etc.
I did not have this problem before we got a new router, so I'm thinking this TV isn't compatible with whatever the latest WIFI technology is, and it has a problem with some "smart" feature that the router might have to get it onto the best bandwidth? I'm not an expert.
So my questions are a) is there a known fix for this, and b) is anyone aware if this is an issue for newer TCL TV's? I'm researching getting a new one if this isn't fixable and leaning towards a TCL QM7K, but not if this is a common thing. Thanks in advance.
