You will need the following two files:
Assuming that you have pppd installed on your machine (duh), place the file chat-Verizon-4G-LTE in /etc/ppp directory. Similarly, place the file Verizon-4G-LTE in /etc/ppp/peers directory.
Now insert the Pantech UML290 modem in a USB port of your machine and use the following command to connect:
sudo pppd call Verizon-4G-LTE
Update: If the above method fails with the error message mentioned in this comment, then please try the solution described here.
Enjoy!!
Pagey: No luck with this method either. I did a ps to see if pppd is running and it does not run. I ran sudo pppd call Verizon-4G-LTE with no luck. any advice? I am in full 4G coverage and the UML290 works great with VZ access manager.
ReplyDelete@Lizard32: Sorry to hear that this did not work for you. I would suggest that you start looking through log files in /var/log folder for clues. For example, the file /var/log/ppp-connect-errors might contain information about the problem. Similarly, look for lines containing 'pppd' in the files /var/log/messages and /var/log/syslog. If you see any error messages in any of those files, they will help fix this problem. Let me know if you see any error message.
ReplyDeleteThanks Pagey. Thanks for the lead. Interestingly the ppp-connect-errors file shows Error for the following line
ReplyDeleteAT+CGDCONT=3,"IPV4V6","vzwinternet","0.0.0.0",0,0
ERROR
ATZ
OK
This is the same line that was giving wvdial problems.
Pagey: I may have found the problem. After some investigation I notice that I could not issue a AT+CGDCONT command of any variation without getting an error. This Pantech unit was running software version ending in 230. I changed the unit out with a new one which is running 213 (from 12/2010)and i was able to issue the AT+CGDCONT command with an OK response. This unit running 213 came right up on Ubuntu using your scripts. What version software do you have on your unit?
ReplyDelete@Lizard32: Great work!!! I am glad you got to the source of the problem. I do not have access to Verizon's software to find out the firmware version number of my modem but I will post another comment once I find out. Congratulations and enjoy your 4G modem.

ReplyDeleteThanks. It could have been a hardware problem with that particular device as well. I am a little nervous to allow vzaccess manager upgrade the firmware. So if you find you version please post it as that will probably help determine if its hardware or firmware. I also saw someone else on your wvdial post that had the same problem with errors on the CGDCONT AT command. Thanks for the help.

ReplyDeleteUpgraded the 4G Pantech to the newest release. VZAccess would not do anything unless I upgraded. After upgrade back to the same problem on Ubuntu - Error on any CGDCONT command. Let me know if you upgrade and see this issue.
@Lizard32: The Verizon and Pantech software for Windows is quite terrible. The latest version of VZAccess Manager would not even detect a modem with the older firmware version. So, a non-technical user would be left with no clue as to why their modem is not working. In any case, in order to check the current firmware version and possibly upgrade the firmware, I started the "Verizon Wireless UML290 Firmware Updates" program. To my horror, as soon as I started this program, it started upgrading the firmware on the modem without even asking me for a confirmation. To add insult to injury, the program window disappeared before I could write down the version numbers that it displayed. So, all I remember is that I went from firmware version starting with "A" and ending with "214" to firmware version starting with "B" and ending with "242".
ReplyDeleteAt this stage, my experience was same as yours. The above pppd script no longer worked with my UML290 modem either and failed at the “CGDCONT” command.
So, I simply removed that line from the chat script as well as the last line (the ones that started with ‘CONNECT’) and, lo and behold, the modem started to work again. The updated chat script is available at http://goo.gl/BFEIA. Please try it out (make sure you name it /etc/ppp/chat-Verizon-4G-LTE as before, of course) and let me know what happens at your end.
great work Pagey. I did not try that. The three versions out there are 214 (do not know the full nomencature) December 2010. 230 March 2011 and now 242 (July 2011). 230 and 214 error out on the CGDCONT commands. I just removed that line from the script as you did and it works. Thus this needs to be removed for both 230 and 242. Mystery solved
ReplyDeletecorrection 230 and 242 error out on the CGDCONT command
ReplyDeleteHi I tried to use my Pantech Modem with Pinguy OS and LintMint 11 and I'm still unable to connect. Granted I am a Noob but your directions looked straight forward. Two questions please. How do I fix this issue and how do I install WvDial on Linux, The file I downloaded is wvdial-1.61.tar.gz. I have the 242 Pantech modem and Support already helped me downgrade it to work with 3G. Works fine with Win 7 and XP. I removed the two lines that showed the errors mentioned above 'CGDCONT' and ‘CONNECT’ and now my log looks like this: Connect: ppp0 <--> /dev/ttyACM0
ReplyDeleteSCPLugin: devices added (path: /sys/devices/virtual/net/ppp0, iface: ppp0)
SCPlugin-Ifupdown: device added (path: /sys/devices/virtual/net/ppp0, iface: ppp0): no ifupdown configuration found.
I am using Ubuntu 11.10. I have gone through everything on this blog and no love. Anyone else try it yet?
ReplyDeleteI am also using Ubuntu 11.10 and a Pantech UML 290 modem and have had no luck with any of the scripts or edits.
