Establishing a Cellular Data (PPP) Connection

[Anthony Laskovski]

Hi guys,

Referring to this page:

http://www.multitech.net/developer/software/corecdp/applications/ppp-peers/

I’ve got a Verizon LTE sim, assuming it’s CDMA. The response I get when typing ifconfig ppp0 is ifconfig: ppp0: error fetching interface information: Device not found

I then typed ifconfig, and i was able to see the following, one of which was my computer connected via ethernet.

eth0      Link encap:Ethernet  HWaddr 00:08:00:4A:02:26  
          inet addr:192.168.2.1  Bcast:192.168.2.255  Mask:255.255.255.0

          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:24 errors:0 dropped:0 overruns:0 frame:0
          TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:1636 (1.5 KiB)  TX bytes:1636 (1.5 KiB)

I’d like to find some more detailed instructions in setting up my network connection, and i’d like to know what is the “development system” it refers to in the text below such that I can find these Man files.

See the man pages on your development system for additional chat and pppd information.

Anthony,

What product do you have? (this is in the mLinux forum section but you are referring to CoreCDP documentation 🙂 )

The “development system” is referring to your desktop PC.

I’ve got a Multitech Conduit MTCDT-H5-210L-US-EU-GB

[Brandon Bayer]

Ok, then you’ll need to follow the mLinux instructions for ppp on this page:

Thanks Brandon.

I’m up to step number 5 and having a similar problem to what I last described.

# Set "APN" to the APN for your cellular provider 
mlinux-set-apn APN

Done. I set the APN to be vzwinternet. I also tried internet.

# Dial the connection (using /etc/ppp/peers/gsm config)
pppd call gsm

Done. No messages.

# Verify ppp0 is up
ifconfig ppp0
ppp0      Link encap:Point-to-Point Protocol  
          inet addr:33.140.12.18  P-t-P:33.140.12.18  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:7 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3 
          RX bytes:106 (106.0 B)  TX bytes:145 (145.0 B)

ppp0 was not found

Anthony,

You can see what’s happening in /var/log/messages.

It’s likely not working because you have an LTE SIM, but the Conduit doesn’t support LTE.

If you have more questions relating to compatability, open a support case here: http://support.multitech.com/

Ahaa I see. Thanks for pointing that out. Is there a Conduit that supports LTE? I see in the product datasheet that LTE is mentioned in the roadmap.

[Brandon Bayer]

Anthony,

Nope, currently we only have the H5 model which doesn’t support LTE or Verizon. I believe these are on the roadmap, but we don’t have a date yet (except for no earlier than next year).

Hi Brandon,

I spoke to our contact at Verizon, and he indicated that they do not have any HSPA+ cards. This is something available on AT&T and T-Mobile.

The sales datasheet at the link below shows Verizon approval spanning across both columns of the LTE (yet to be available for purchase) and H5 model (HSPA+). Based on all the information i’ve now gathered it seems that the sales datasheet is incorrect, as HSPA+ is not available on the Verizon network, therefore the H5 can’t be approved for Verizon. Is this correct? Does this need to be raised with someone else now?

[Brandon Bayer]

Anthony,

Ah, yes, that datasheet is incorrect! Only the LTE will support Verizon. I’ll forward the discrepancy internally.

-Brandon

[Anthony Laskovski]

ok cool. thanks for helping

Hi Anthony,

MTCDT-H5-210L-US-EU-GB conduit mlinux gate is supporting to “CURL” ?
please let me know..

Thanks in Advance…

[Jason Reiss]

Yes, curl is available on mLinux.
