why aws s3 transfer acceleration is not working

Question

I have to upload some files that are between 3 and 7Gb to s3. The default upload speed when using the AWS Console is about 1.3 Mbs. I read about transfer acceleration here:

https://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration-examples.html#transfer-acceleration-examples-aws-cli

So I followed the steps:

1. Turn on transfer acceleration on the bucket, in the console. Then...

   
   aws s3api put-bucket-accelerate-configuration --bucket [bucket name] --accelerate-configuration Status=Enabled
   aws configure set default.s3.use_accelerate_endpoint true
   aws s3 cp some_file.txt s3://[bucket]/some_file.txt --region us-east-1 --endpoint-ur http://[bucket].s3-accelerate.amazonaws.com

It uploads still at the same 1.3 Mbs. I am WFH so subject to Wifi, but still, I wish it could be better. Is there anything else? Do I need to use Python boto3? I was hoping this would be quicker. Any help?
