My name is ***** ***** certified professional with over 10 years experience. I will be glad to assist you with this.
I am sorry to hear that you are having this issue.
You will need to reset the tv and then do the network set up for your new router.
To reset the Panasonic, press and hold down the volume minus button on the tv and the menu button on the remote at the same time for 5 seconds. Self check will appear at the top of the tv screen, at this point press the power button on the tv until the tv powers down. When the tv turns back on, go through the set up.
Please let me know if you need any other assistance.
Please take a moment to rate my service positively by clicking one of the stars at the top of the screen then click on submit.
Thank you very much!
