Wi-Fi & connectivity

[warev]

I'm using a Phillips roku tv it had worked perfectly for the last 6 months. A few days ago it started having a lot of trouble opening apps and playing programs, now every app is nonfunctional. When I open it they just stay on the logo screen when I hit the star button to veiw details is tells me I have no internet connection however when I go into network settings the network test shows a strong signal. All other devices work fine so it's not a problem with the internet itselfI have resetthe router unplugged and replugg the TV turned it off and back on done a system restart through the power menu deleted the wifi info and made seveal threats to dunk it in a tub of water nothing has worked. I'm stumped how the heck can it clearly be connected to internet and show a strong connection on all the network menus and tests but all the apps say it is not connected to internet? Any ideas on how to fix this would be appreciated

I feel like you've tried everything, but I have to ask if you're using any VPN or content/ad blocker?  You might want to try connecting to an alternate network like your phone's hotspot, if possible.  It's not meant as a fix, but if it works through a different network then we can try to figure out what the problem might be with your current network.  If you have other network equipment like a gateway or modem you might want to restart them by unplugging the power for several seconds.
