lost ability to tether using android phone

[Donatas G.]

Hi,

perhaps after the latest upgrade to 15.10 my computer can no longer connect
to internet via android mobile phone connected via usb cable. It used to
work, and I can still do that with a windows computer, so the android phone
is not to blame.

I recall that previously ifconfig would show that I am connecting through a
usb0 device. Now it has a strange name "enx86fe93fa90d8"... The computer
does get an IP address from the phone, but I can neither ping the phone
itself (the "gateway") nor ping any website or IP address on the net. All
the other parameters do not say a lot to me, but I am including those as
output here below.

Anyone has encountered this problem? Any idea why it fails to work? Would
be grateful for ideas what to do next.

Below are some outputs of the relevant commands.

Sincerely

Donatas Glodenis
