AX2400 Issues

[Link2959]

Got this router and it's been perfect for a few months but this week specifically it's been causing me issues.

Currently I can watch videos, stream shows, etc. 

As soon as I load up a game or discord voice chat I begin to lag and also rubberband in games and frames drop.

I've reboot is a few times and even factory reset it today and still the problem continues.

Not sure if this is common or what the issue can possibly be.

what actual router do you have (look at the label as it'll have a model number on it)?

what firmware is on it? 

What modem/gateway is it connected to? 

What speeds (both upload and download do you pay for)?

Are you using it over wireless when you have issues or wired? 
What band are you using if its wireless?
