Check Wi-Fi Status:

 First off, you need to make sure that the Wi-Fi network which you are trying to connect to is active and stable. Try to connect your respective Wi-Fi network to another device to confirm that the internet is working fine and there is no issue with the Wi-Fi.

Restart Your Router:

 Sometimes, even by just switching off and back on the internet connection after a small break you could possibly sometimes resolve problems with the IPTV device connection with the network. After restarting the Wi-Fi router, you need to connect your NVIDIA Shield IPTV device. It sometimes recovers the connection by itself after turning the router off for 30 seconds and then turning it back on.

Forget Wi-Fi network and reconnect to it:

 In order to forget your network, go to Settings > Network > Wi-Fi > Select your network > Forget Networks. Once that is complete, you will need to rejoin by choosing the network once again and inputting the right password to your Wi-Fi router.

 
Move closer to Wi-Fi Connection:

 If you are in a situation where you observe that the Wi-Fi signal that you are experiencing is poor, you may want to consider relocating the Nvidia Shield closer to the router. The signal may be disrupted by impediments such as thick walls and other obstructions.

Examine the Software for Any Updates:

 It is very crucial for the strong connection that the firmware of both the Nvidia Shield and the router should be brought up to date. It is possible that connection issues are caused by an outdated firmware version. In case of outdated firmware, you need to look for available updates and run them if any available. 

Change the Wi-Fi Channel:

 If there is interference from other nearby devices that are using the same channel, you should change the Wi-Fi channel on your router's settings in order to optimize the signal. 

Reset to factory settings (if necessary): 

In the event that none of the aforementioned methods are successful, it is possible that a factory reset will be required. Select Settings > Storage & Reset > Factory Data Reset, and then proceed to adjust your Wi-Fi settings when you have completed this process. 

You should be able to restore Wi-Fi connection and continue streaming video on your Nvidia Shield if you complete these instructions in the correct order.
