I have an Orbi RBR750 with 1 Gig internet but issue with lagging on LG TV with WiFi6

1. what firmware is on your orbi? 

2. what modem/gateway is it connected to?

3. what lg tv is it? 

4. is it a specific app or all of them? (test it)

5. are you connected to the 2.4ghz band or the 5ghz band? (for the tv)

6. is the tv connected to the router or a satellite?
