Re: [Speed] Suddenlink Cable internet Lag the dns server should not effect the bandwidth at all. Dns is more of a lookup tool that points what you typed into the bar to an ip address somewhere on the internet. Without dns you'd have to type in an ip for every site you want to go to.
Once you have made a connection to the server (website) that you are going to, you are no longer using the dns servers.
If you are not uploading anything then the uplink buffer wouldn't have any meaningful effects on your gaming, and especially not on streaming a Netflix movie which involves little to no upstream traffic.
Out of curiosity, are these test results that you are posting taken while your connection is working fine, or when you are experiencing trouble?
