Hello,I am the person that will be helping you today.
You won't need to enter any IP address information. You just need to connect your TV to the wireless network and the TV will do the rest. Does your TV see your wireless signal or any other signal for that matter? May I ask for the brand and model name of your wireless router or your wireless modem?
Once I have the above requested information, I will be able to give you the correct answer.
I look forward to your response,Jason
