Recently changed to a 300/300Mbps plan but upload speeds still capped at 40Mbps.

Hi, I recently switched to a 300/300 plan with unlimited data, but my upload speeds are still capped at 40Mbps.  Anyone know how I can get my upload speed up to 300?

Hello @Silent3eatz, thank you for taking the time to leave a post. Sorry to hear you're experiencing issues with your upload speed. Could you let me know if you're using an Xfinity Gateway or your own modem? Also, are you connected via Wi-Fi or using a wired (Ethernet) connection?
