I was trying to follow the tips posted for Huawei E3372s + Linux (Rasbian), Incoming connections problem.
I'm running Raspbian Jessie 8.0 on a Raspberry Pi 3.
I've also tried this on a Pi 2.
My LTE USB Stick is marked E3372.
Is that much different from the E3372s?

Note: hardwired Ethernet connected at the start of this exercise.

I tried sudo usb_modeswitch -v 12d1 -p 1f01 -V 12d1 -P 14DC -J

$ sudo usb_modeswitch -v 12d1 -p 1f01 -V 12d1 -P 14DC -J 
Look for target devices ...

 No devices in default mode found. Nothing to do. Bye!

what's on lsusb?

what's on ifconfig?

After I disconnect the Ethernet, I try to do a ping

$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=50 time=92.2 ms
64 bytes from 8.8.8.8: icmp_seq=2 ttl=50 time=92.0 ms
64 bytes from 8.8.8.8: icmp_seq=3 ttl=50 time=83.4 ms

traceroute 8.8.8.8 also shows positive results.

The Modem seems to be connecting to the outside world.
But I still can't make contact with another Raspberry Pi with the same setup.
And I can't reach the Google home page on Firefox or Chromium.

the stick still seems to be configuring as a memory.

how do I get it to connect as a modem?
what's the trick?
