Practical speeds nowhere near "symmetric" nor consistently high for 1Gbps service
A few days ago, I engaged in a chat with ATT about my 1Gbps service. That day, speed tests indicated I was getting 58Mbps down and 150Mbps up +/- a few Mbps. I indicated I was used to practical service speeds of many hundreds Mbps up and down, and it was generally pretty symmetric. When I say many hundreds, I mean more than 700.
Today I perform another speed test and I get 448Mbps down and 849Mbps up. This is of course much better, but suggests some manipulation is being performed. My equipment, my connections, and my load on my network are a virtual constant.
Of course they had me log into my Router/Modem (Arris BGW210-700) and of course the modem's speed test is symmetric and close to 1Gbps.
And so, what is really going on here?
Thank you for your assistance.
