For now you should discover and be told that QoS is not the answer. There are Gaming routers that prioritize gaming but again you read where they don't work to reduce the lag to the point you can't notice it.
Gamers do not share their connection.
I would like to be able to make my Xbox top priority for bandwidth because whenever I watch Netflix on any other device I can't play COD MW3 without extreme lag (works fine when not watching Netflix). QoS settings on this router confuse me and I have no clue what to select..........I have these questions:
Select the Protocol and TOS BIT value.
Source IP Info
Destination IP Info
Any help would be much appreciated. Thank you!
