High Speed Tethering to New PC

[MistaB]

Hi.

I am appealing to you guys who tether from your phone to your pc. Mine is working but I would like to find out how to use all of the available speed, if that's possible. 

I have two phones, a Z Flip 2 and a S23 Ultra and both are giving roughly the same results around 800 Megabits per second.

When i connect to USB  or USB /c (both 3.2) on my pc I can't get above 320 - 350 Megabits per second, from either phone. The same speed happens on the USB2 sockets too. 

Ideally, I would like to use the z flip as a mobile dongle and my s23u for normal use. 

USB2 has a max of 480mbps and USB3.2 has a max of 20gbps - google || Of course I don't know if that is any data type transfer or just certain types. However on the face of it, it should be working. 

Any ideas ?

TIA

Had a Z Flip4 arrive today so tested that and as expected, usb2.0 so no change. Then I realised I now have the cable so I can check what the s23ultra can do and sure enough, it has USB 3.2 so tried it and sure enough, hit 600mbps (typical speeds today) alas I neither want to use the s23 as a MIFI and it keeps disconnecting the tether for some reason, randomly a few or 10 or so more seconds after successful connection and won't reconnect unless I touch the tether choice again. 

However this does mean definitively we have a solution. 

A USB 3.2 cable and socket will allow speeds above 320-350mbps, 600mbps on this test today. I expect more on better connection days. 

Thanks for the replies.
