Upgraded from longtime 1Gbps plan to a new 2Gbps plan and my upload speed fell from 370Mbps to ~70Mbps?
I’ve been on a Comcast/Xfinity 1Gbps plan for several years and I’ve been paying $30 extra each month for unlimited data. Since all of their new plans (since 2025) come with unlimited data by default, i decided to ‘upgrade’ to a current 2Gbps plan and save $30/month in the process. The download speed immediately shot up from 1.3Gbps on average to 2.3Gbps (as expected), but the upload speed had been reduced from the 370Mbps speed that I’ve grown accustomed to over the years to a paltry 70Mbps. Since I rely on upload speed more than I do download speed, I’m unhappy with this. I even asked the text chat sales representative if my upload throughput rate would be adversely affected by the switch and I was assured that it would not.
Know that I own my own modem (Unifi UCI) and I rebooted the modem a few hours after the new service was provisioned and it did not make a difference.
Also of note Xfinity‘s website claims symmetrical data throughput speeds of 2Gbps down and 2Gbps up.
Is this known/expected “feature” of switching to one of Xfinity’s current Internet plans? Is there anything I can do to get back to 350Mbps upload speeds?
