USB Tethering very slow on Linux

okuteur — Sat, 25 Nov 2017 13:18:27 GMT

Hi,

I'm using a laptop under Linux (Ubuntu 16.04.4) and a Sony Xz premium ( Android 8.0.0).

When i use the usb tethering (with the usb-c Sony cable) the laptop download is very low, less than 1Mbps, with a lot of RX error:

$ ifconfig
enp0s20f0u2 Link encap:Ethernet HWaddr 82:58:c8:0a:63:fb
          inet adr:192.168.42.249 Bcast:192.168.42.255 Masque:255.255.255.0

          Octets reçus:48598676 (48.5 MB) Octets transmis:16732331 (16.7 MB)

same test on my phone:

I have try with another linux distro and it's the same behavior.
I don't have any issue with the same laptop and Windows 10.

i have read that the Oneplus user have the same problem and find a resolution with a OS phone upgrade here .

Can someone help me ?

Same issue here.

It is a shame that OnePlus successfully fixed the issue but Sony doesn't.
