That's what I was wondering. I have an external USB device, the=20
Pantech UML295 (Verizon being the carrier.) It gives me this=20
Mar 31 17:25:26 tp kernel: [379939.016993] cdc_ether 3-6:1.0 eth1:=20
register 'cdc_ether' at usb-0000:00:14.0-6, CDC Ethernet Device,=20
All I have to do is to DHCP on this Ethernet interface, and=20
"mbb.vzw.com[192.168.32.2]" becomes my gateway. It gives me a
little HTTP interface ( http://mbb.vzw.com/ ) to manage the
connection. Click connect, and Bob's your uncle, I'm online.
The internal mini-PCI cards do not have this? Or does cdc_mbim=20
conflict with cdc_ether? (Hmm, I guess not, unless cdc_mbim was=20
blacklisted somehow; I have both drivers.)
I'm looking at a Gobi 5000 for my Thinkpad T440p, but it is a $200=20
gamble, more if I have to pay for SIM activation. (I'm guessing I=20
might be able to use the Pantech's SIM for testing?)
It would be nice to have a real, routeable IP address, but the
important thing is to be able to USE the Internet connection.
So, Bj=F8rn, do you need another tester for the Gobi? Does the=20
prognosis look good?
