Thanks.
I also 3D Printed a USB Cover with copper tape all around it, and I also added the copper tape on the tip of the USB Flash Drive.
My internet speed increased from almost nothing to 35Mbps (Download) & 15Mbps (Upload).
It’s better, but still very far from 300Mbps.
The ping is very weird. It’s around 500ms (Download) and 1500ms (Upload).
Thanks
