I’ve been using the tethering mode with the L5 but the internet speed is painfully slow (at least an order of magnitude lower than internet speed on device and tethering speed from android).
Apparently such an issue was already reported before and fixed via
nmcli connection add type ethernet ifname usb0 ipv4.method shared con-name tether
I’m not sure why enabling sharing from the GUI leads to such a slow connection but I’d like to know whether it would it be possible to configure the settings by default such that tethering speeds is good by default.
