I disconnected my smart tv from WiFi and just use my own home network. By setting up a static ip address on both my tv and media server through the eXXXX device, and connecting the two via Ethernet cable, I can access any media I have saved on the server from the tv with little to no lag. This allows the tv to continue being “smart” to some extent, but only with the addresses I specify. It’s also arguably better since Ethernet speeds are usually 100+mbps for me against 2mbps wireless speeds.
