Unable to Upload Large Files over WiFI

I have an XB8 gateway and speed is not an issue (app diagnostics show I'm getting 118% of plan speed to gateway).  However, if I try to upload a large file (anything over 100MB) the upload fails.   I've tried with different devices and uploading to different targets.  If I am not on my home network I am able to complete the upload without an issue.   I am also able to do uploads when connected directly to the gateway.

I work from home and it is imperative that I be able to upload larger files for clients.   Maintaining a continuous direct wired connection to my gateway is not an acceptable alternative nor is having to go somewhere else when I need to upload large files.    

Wi-Fi diagnostics on the app show no issues and that I am getting a strong connection from my work laptop.   Seriously considering ditching this gateway for my own device.

The easiest way to share large files online is often by using a cloud storage service like Google Drive or Dropbox, WeTransfer or Filemail. These services allow you to upload the file, generate a shareable link, and send that link to the recipient, who can then download the file.

That's not the issue.   The issue is getting files uploaded to those services.   How can I share a link if I can't upload the file?

I have seen similar issues with laptops I have worked on, and it is usually the processor getting too hot from the extend period of use.  Try adjusting your power settings for processor speed to 10% low and 90% max.  If you get better performance, it would indicate that it is your problem.  You may have to adjust the max settings even lower, depending on your laptop.  When they get hot, the system throttles the processor and chipset, and this can cause the issue you are having.  Please give it a try and circle back with the results.

There's not a heat issue with the processor.    This is my work laptop so there's not anything going on that would cause consistent significant CPU usage.  The only things running are Outlook, Teams, Edge and all the necessary background processes and the CPU shows about 25% utilization.   The CPU is a single socket Intel Core i7 with 14 cores.  I use Core Temp to monitor the temperatures and across the board, they are all hovering around 40 degrees Celsius.  After shutting down everything other than Core Temp and all the background processes, the CPU is now below 10% utilization.  I then tried to upload a 10GB file to my company's internal SFTP site and it failed after only transferring less than 1% of the file with a network error.    Temps for all the cores stayed below 45 and CPU utilization never got above 10%. 

I'm certain this is an issue with xfinity.  I have seen too many posts in this forum with others having the same issue.   I was travelling last week and was able to do this same upload successfully using both my hotel's wi-fi and the wi-fi at a colleague's home (not an xfinity customer).
