myself and my son's are PC gamers, but we've noticed that we're getting higher and higher pings.
i tried a few speed test's and other DSL tests and my "bufferbloat" is rubbish. I think, going by a few internet searches
that this can be helped with editing the QOS? can i do that on a Smarthub?
or if not anything else I can try?
There is no settings for QOS. You need a 3rd party modem/router
You can DMZ one device on the smarthub from Advanced Settings - Firewall -Configuration but read the caution before you do
