Uplink speeds

I'm getting 681 mbps in my downlink but only 5.7 mbps in my uplink. Why has my uplink becpome so slow, and what should it be and how can I get the number up?

Re: Uplink speeds

Your answer was very instructive and informative, thank you.  I probably should have also noted that I had installed a new Netgear Nighthawk Model C7100v device in the past 2 weeks.

 

After reading your answer and a loooong talk with a Comcast tech rep, I learned that the 'boot file' (it may have another name) that Comcast uses when they were activating my new Netgear modem/router is a 'lesser' one than the boot file used when a Comcast supplied device is used. Thus, the user gets slower down and uplink speeds. It looks like a business strategy that 'encourages' you to either use a Comcast device or reduce the plan speeds

Since I had been getting 700-800 downlink and 30 uplink speeds before, I guess I'll return my Netgear and go back to my $14 a month Comcast device.

Re: Uplink speeds

If you are subscribed to the gigabit speed tier, you will not be able to get gig speeds with that Netgear C7100v. It's only DOCSIS 3.0 capable. You'll need a DOCSIS 3.1 capable device. Otherwise it will default to using a lower speed boot / config file.
