Hi, can I know whether I can set up different ssid for gaming and besides gaming usage? Like 2.4g/5g. Or how to set up gaming as first priority while others streaming/downloading doesn't affect game's ping. QOS/Traffic shaping/Bandwidth control works?
If you have a dual band router you could set it up so that only you use one or the other (2.4GHz or 5GHz) and everyone else is on the other. For gaming you do not want anyone else using your bandwidth or increasing your latency, which is already an issue for gaming when using wireless. QoS is not a good solution to make wireless gaming work better when there are multiple users.
So then you would set up an SSID on the radio that you will use that is different from the other and obvious for other users not to mess with -- like Private_Gaming and keep the passkey a secret only known to you. The other SSID would be something else and everyone that uses it will get the passkey.
Assuming you have a good plan with your ISP, say at least 10-20Mbps, your best gaming experience will be this an Ethernet cable connection or if not feasible then use a pair of AV1200 or better powerline adapters -- either will have MUCH better latency than wireless.
If you have a limited bandwidth plan, any other users will adversely impact your gaming, although most modern Internet connections are adequate unless you are on DSL at the fringes of the provider area far from a CO.
