I'll start by saying I do NOT use a physical connection to the TVs because I do NOT use any of the "features" (aka bloatware). In fact, I delete as many of them as I can from the apps ribbon. ALSO, I've experienced a couple of lightning events in my years since broadband was in the house and in EACH event, the wired Ethernet has provided that succulent low resistance low voltage path to ground the lightning seeks and most things physically connected were damaged. So as not to go a drift here, surge protectors do NOTHING for lightning.
NOTE - If you already have a dual band router (2.4 and 5.8) with both radios enabled, AND all your Computers can connect on the 5.8GHz spectrum, move them all to that network, leave the TVs back on the 2.4GHz spectrum and you're go to go. I unfortunately need to leave some devices back in the 2.4GHz spectrum so I "cheat" by adding a second 2.4GHz network. I also have a few wireless HDMI devices in the house that use the 5.8Ghz spectrum and I try to keep it as open as possible. I'm on a large lot and don't see a lot of neighboring networks in the 2.4Ghz spectrum so YMMV. If you have an android tablet, grab a copy of WiFi Analyzer from the Store to watch what is around.
SO, if you still want to continue:
My primary router is setup to hand out IP addresses (DHCP), connect to the Provider network (WAN/DNS), ... as you should already have set. Since you said you're "new" to this stuff, I'd make a recommendation you use a LAN IP address other than 192.168.0.X OR 192.168.1.X as these are too often in conflict with defaults on devices. Go for something like 192.168.1XX.X
NOTE the LAN IP, the SSID and channel you are currently using. I turn off Auto channel and pick my poison! For example, let's assume I have my Wireless SSID set to MY-NETWORK and fix the channel to 1. I use a DHCP reservation in my primary router to hold an IP for the secondary router from the assignment pool and then use THAT IP for the LAN IP in the secondary router. This allows me to still access the administration functions of the secondary router without issues (e.g. 192.168.1XX.2).
I took an old router, configured it with the LAN IP mentioned above (192.168.1XX.2), created an SSID different than above (e.g. TV-NETWORK), disabled DHCP, set the WiFi channel to OTHER than above (e.g. 6 or 11 depending on your environment), connected the two routers LAN port to LAN port and that now provides another WiFi access point on the network on a non-interfering channel.

Can't remember exactly what it was off hand but I knew it was associated with the TV or the TV's remote when I saw it.
I tend to get lost with wifi network issues though. Can you explain a bit more about what you did? It's not clear to me.
