Upload speed

I switched my cable modem from Netgear CM1000 to CM3000 today. I noticed that my upload speed did not significantly increase & was still capped at 30 mbps under Xfinity 1G plan. Is there anything I can do to boost my upload speed?

user_8me2h3 Thank you for taking the time to reach out to us here on our Xfintiy Forums! I definitely understand the frustration if you were expecting your upload speeds to increase. When you log into the Xfinity app do you see that your upload speed should be more than 35 Mbps? Also have you tried any troubleshooting in the Xfinity app to send a provisioning signal to the new modem?
