Hi first time posting, I was wandering why even thought the wireless connection is 100% on my xbox wirelessly and and even when connected using an ethernet cable I am getting random bursts of lag? It is even happening on my firestick and I'm just wandering if anybody has a way to fix this issue? I have checked the location assistant and it says it's in the perfect place yet I am still getting network and connection issues. Is there a port I can open on the router that  will improve the connection between the router and the extender or is it an issue with the wifi connection in the house? Thanks for any replies.
