WP7611 Trouble Getting Data Connecting to Verizon

IoT Modules
1

Hello All,

I’m using a WP7611 on a custom board running OpenWrt. Right now I can use modem manager and it will say the wp7611 is connected; however, looking at the developer portal from the Verizon side, it will say it is “active”, but it is not sending data through.

The Verizon support suggested my problem may be with the configuration on the WP7611 side. I’ve set the modem to use the Verizon firmware, but I’m not sure what further configuration to do. I did try the at!SCACT command for setting data connection for Verizon, but that did not seem to help.

Thanks for any advice or ideas!

Hi @justin2
In order to troubleshoot the issue, please share with me some information as below:

  1. What firmware version is your WP7611 running?

  2. Have you installed the latest driver for your PC? If not, please install latest driver by following the link below:
    Mobile Broadband Package for Linux (SDK, Drivers, Documentation)

  3. Has this issue happened before? Or is this the first time?

  4. How many WP7611 module did you observe this issue? If It’s just only one, could you please retry on another WP7611 module?

  5. In which of the following scenarios did you make a data connection:
    a) You have made a data connection from your WP7611 to Verizon side
    Or
    b) You have made a data connection from your host (via WP7611 module) to Verizon side

    Please share with me the step-by-step you did.

  6. Please share with me the output of commands below:
    ATI9
    ATI8
    AT!ENTERCND=”A710”
    AT!GSTATUS?
    AT+CPIN?
    AT+CGDCONT?
    AT+CEREG?
    AT+CREG?
    AT+COPS?
    AT+CSQ
    AT!SCACT?
    AT!SELRAT?
    AT+KSRAT?
    AT!BAND?
    AT!IMPREF?

Thanks,

Hey, Thank you for responding.

I’ve been working that part of my issue with an FAE, and what I needed to do was to create the ppp interface with pppd. I’m now much further along and I dont think the problem is with the modem itself.

for those curious, here is the chatscript I ended up using

BORT   BUSY
ABORT   "NO CARRIER"
ABORT   VOICE
ABORT   "NO DIALTONE"
ABORT   "NO ANSWER"
ABORT   DELAYED
ABORT   ERROR

TIMEOUT 10

"" AT
OK "ATD*99***3#"
CONNECT

And here is the options file

noauth
connect "/usr/sbin/chat -v -t 5 -f /etc/chatscripts/wp7611-chat"
debug
/dev/ttyUSB2
115200
defaultroute
noipdefault
usepeerdns
lcp-echo-interval 20
noaccomp

I’m still having a problem where I cant seem to ping through the ppp interface, not even the gateway or the DNS I get assigned through the ppp connection.

Hi @justin2

Could you please share with me some information as below:

  1. What firmware version is your WP7611 running?
  2. Currently, I can still start PPP with my module. So please share with me your script files related to your PPP start process so I can recheck with my module.

Thanks,

I also have a WP7611 with older firmware on it that experiences the same issue.

As for the ppp connection, I think what I shared above is everything i need.

/etc/chatscripts/wp7611-chat 
BORT   BUSY
ABORT   "NO CARRIER"
ABORT   VOICE
ABORT   "NO DIALTONE"
ABORT   "NO ANSWER"
ABORT   DELAYED
ABORT   ERROR

"" AT
OK "ATD*99***3#"
CONNECT
/etc/ppp/options 
noauth
connect "/usr/sbin/chat -v -t 5 -f /etc/chatscripts/wp7611-chat"

lcp-echo-interval 20
noaccomp

After making those files i can just run pppd and a ppp0 interface appears in my ifconfig and i get an IP and all that. Despite that, I still cannot ping 8.8.8.8 or even the new gateway i see assigned from running the route command, 10.64.64.64.

Thanks again for your help

I had a similar issue with FX30 on AT&T. I found that the issue was resolved when the PDP type was changed to IPV4 instead of dual stack. This is accomplished as follows: at+cgdcont=1,“IP”,“<APN.NAME>” instead of at+cgdcont=1,“IPV4V6”,“<APN.NAME>” (VZN uses CID 3 instead of 1). Dual Stack is supported, so I assume I am missing some ppp configuration to accommodate it. After this change, I was able to ping 8.8.8.8 over the ppp0 interface.

Turning off IPv6 worked, you’re a hero!

Really thank you, this issue has been bothering me for quite a while.

:slight_smile: I’m glad it worked.
