My new Q90T TV keeps knocking out my home networks internet connection to all devices. Tried wired, wireless, Static, DHCP. Also tried straight to the back of the modem. That worked for a few days. Did not have any issues using the previous Smart TV.
Perform a network status test to help you choose which guide you need. Navigate to Settings > General > Network > Network Status and run the test. Pay close attention to any error messages, and whether there is an X between the TV and the router or between the router and the globe.
Disconnect some of your other things that are connected to Wi-Fi:
The more things you have connected to your Wi-Fi network, the weaker the signal will be. If you have 2 tablets, 3 phones, a refrigerator, and an Xbox, the signal could be very weak. Disconnect all other Wi-Fi devices from the network and then try to connect the TV.
If this does the trick when none of the previous steps worked, it means you have more devices connected than your router can handle and you should upgrade your router or connect fewer devices.

Power cycle your network equipment.
Try connecting to a different network.
This is a troubleshooting step to help determine what the issue might be. For instance, if a mobile device with hotspot functionality is available, have it create a network and try to connect the TV to the hotspot. If any other networks are available, they can be tried as well.
Note: If the TV can connect to any other network, service is not required, and the issue is with the network that you're unable to connect to. Contact your ISP if they provided the router, or the manufacturer of the router if it was bought separately.
If the issue continues, we recommend contacting your ISP or the manufacturer of your router for further assistance.
