Xfinity app and speed test showing speeds from previous plan

Hello,

• I recently upgraded to a 1000 MBPS plan with the help of a live agent on 7/3/2025, however the Xfinity app still shows my previous plan of 600 MBPS and the internet usage has not shown any updates from past two days. The Xfinity website shows the new speed, I am unsure of the discrepancy between the two.
• I have checked my modem and it is on the list of approved customer owned modems and is capable of the new speed.
• The modem has been restarted a couple of times through Xfinity assistant's troubleshooting steps and also with the help of live agent, however I still continue to get speeds in the range of 600 MBPS. During my last conversation with the live agent, I was told that my modem's firmware was updated and a new config file was pushed to my modem so that it transmits at the new speed, however when I ran a speed test directly from router(hardwired), I am still getting the older speed of about 600 mbps and I have checked that my NIC is capable of GBPS speeds.
  
  Can Xfinity please look into this ?  

Thank you
