Upload speed still hasn't updated after neighborhood upgrade

Hi there,

Xfinity just finished network upgrades in my neighborhood (Glen Cove in Vallejo) on October 15th, and I can now see the new 1 gig and 2 gig plans showing up for my address with the faster upload speeds.

I'm currently on the 1.2 gig plan with a 5 year contract, and I rent the xb7 gateway with unlimited date.  Even after restarting my modem, my upload speed is still stuck around 40Mbps instead of the new upload speeds.

I tried reaching out to phone support, but the agent kept trying to switch me to a more expensive plan.  Can someone take a look at my account and help me get the updated upload speeds without changing my current plan?

Thanks!
