WE826 with MC7354 did not work with Sprint


#1

I have a Sprint business account with Static IP service.

MC7354 with WE826 doesn’t not run. Router WE826 has GoldenOrb. APN settings: “n.ispsn”. The MC7354 sees the SIM-card because it can show me on the screen the SIM-card ID, but no phone number was recognised assigned to the SIM-card.

I also was trying to test it with Verizon SIM-card: it did not work as well. The modem recognised the SIM-card and shew me on screen phone number assigned to the SIM-card but no web-traffic. I tried two APN settings: “vzwinternet” and “internet” - both did not work.

On Sprint you should be using a Sprint PRI and FW.
at!priid?
Did you switch the FW to Verizon before testing with a Verizon SIM card?


#3

I am not sure what is “PRI”, “FW” and “at!priid”. Can you, please, explain a bit about that.


#4

FW-> modem firmware
PRI-> modem carrier configuration

can you collect the followings from the modem’s AT channel?

This modem was provisioned with Generic configuration (PRI)

you need to upgrade the FW to Sprint:
https://source.sierrawireless.com/resources/airprime/software/airprime-em73xx_mc73xx-fw-package-latest-release/

Sprint normally uses “otasn” on PDN1 but is is only used by Sprint for over the air provisioning.
Data “n.ispsn” is on PDN3. FW upgrade should take care of that.

I understood. Will try to upgrade firmware and let you know about my results. Thanks for you help.


#10

I did not find a way to upgrade firmware via router. Is it the only one way to do that by mini PCI-e to USB adapter on PC?


#11

If the platform doesn’t support upgrades then yes.


#12

Got issues with upgrading: when I execute 9999999_9902350_SWI9X15C_05.05.63.01_00_SPRINT_005.037_000.exe it shows this:

Please check if you have the drivers installed properly on the PC and if the Sierra Wireless network interfaces (Device Manager -> Network adapters) and AT (Device Manger -> Modems),NMEA,DM ports (Device Manger -> Ports) show up.
