Welcome to TPG Community!
We have located the account using your community details. We have checked the status of your connection and we are not detecting any fault on the line or network that may affect the upload speed.
Did you run the test using only one device connected via ethernet cable or Wi-Fi?
Are you able to check the speed again? Please make sure that there's only one device connected and there are no programs running on the device background.
We'll wait for the test result. Thank you.
Thank you for the screenshots.
Upon further checking on your account, it seems like you're now using a TP-Link modem. I had to make some adjustments on my end so your modem can have the right details for the connection. Can you try and test your speed again? I believe this should now reflect the correct upload speed.
