Hi Abubaker,
Thank you for reaching out to us in our community and welcome, Sorry to hear you are suffering latency when gaming since switching to the Hub 4.0, I have tried to have a look at things our end however wasn't able to locate your account with the details we have for you.
When you are playing is this via a Ethernet cable or WIFI?
So we can get a better idea of what's going on I would advise you to set up a free “Broadband Quality Monitor” to continually monitor the state of your connection and record any network dropouts.
It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with us. Make sure you uncheck the “ignore ping from WAN side” box in the settings if you see a wall of "red" - note it will take an hour or two to start seeing a sensible picture. please run this for 72 hours and post the results here so we can have a further look into this for you.
Kind regards
Paul.
