CBK40 slow upload speeds
Just connected my Orbi, and my upload speeds went from 35-40Mbps to6. Any ideas?
Hello Txs for the response. My ISP is Xfinity and I have the 1000mps download speed. I use the Orbi app or Speedtest for testing speeds. To fix it I tried restarting the devices. Didn’t change coax cable as it is the same one that was hooked to the gateway from Xfinity that I had. And yes I just installed it and was using Xfinity equipment
These were my upload speeds before
please post a screen snip of your modem connections page.
also try using a computer hardwired to the modem and try the speedtest app.
you didn't put if you've tried anything to fix the problem.
I get that you didn't try replacing the adapers. But if you were using a docsis 3.1 modem from your provider and the cbk40 is only a docsis 3.0 device, its a little more sensative to line interfernce. Try removing any splitters, amplifiers ,attenuators, kinked lines, or extended runs.
Another thing is the CBK40 is only rated to 500mbps per comcast. it can handle up to 900mbps but comcast only certifies it for 500mbps. having a gig connection through comcast with the CBK40 is just paying for speeds that its not rated to.
