Re: Trouble connecting my smart TV to the Internet.
I commend you for the details you've shared thus far, and it seems like you've got quite the setup here. So let's see if I understand this situation correctly:
You have a Samsung Series 5 (COMPLETE model code please!) connected to one router that's connected to another router which is connected to a modem which is connected to your ISP. Thus,
TV > Client Router > Root Router > Modem > ISP
The IP addresses you've provided are as follows:
192.168.x.x (TV) > 192.168.0.254 (Client Router) > 192.168.0.1 (Root Router) > Modem > ISP
Do I understand you correctly thus far?
