Sorry for the late response here, but I wanted to make sure you found the info you needed. This article will show you how to see real-time data usage (speed) of each of the devices currently connected to your network: https://bit.ly/3hbetaZ
Hopefully that was the test you were referring to. If you have any other questions, please let me know.
I just wanted to check in real fast to see if you saw my reply and to find out if you still needed any help on this. If you're still needing assistance, please just let me know and I'll be happy to continue helping.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
