APN not being set properly

@nystrom I am experiencing this same problem. Have you found a resolution?

Hi @Mdobinick,

Welcome to our community!

For the sake of tracking and narrowing down the issue, please kindly create a new topic and provide a more detailed description of the problem you are encountering.

Thanks,

@Mdobinick - We think we just found a fix - we booted using a SIM from a different carrier to get the router to switch radio firmware. Then when we booted it again with the original SIM/carrier, it switched radio firmware again and was able to connect to the correct APN.

@nystrom This sounds promising, thanks for following up. Did you notice any pattern of use that caused your modems to go into the fault state of not having the APN set properly?

@rgatan3 and @Mdobinick , were either of you able to get your modems working again?

@dave.drapac no I have not been able to get my modems working again. Interestingly enough when I talked to Sierra Wireless support over the phone for another issue, I brought this APN issue up and she said this only seemed to affect verizon carriers. There was no answer to how to fix this but Iā€™ll be interested to see if putting a different carrier SIM in will help.

@nystrom Does the other carrier SIM need to be an active card or will any SIM from another carrier work?

@dave.drapac the only lead that we have is that most of these are in areas with not great cell service, weā€™re wondering if they didnā€™t get all the way booted before they got shut down, and so somehow got stuck in a weird spot for the radio firmware? But itā€™s not super clear. We have had a couple clusters of locations where several modems in an area were affected (some more than once) but other areas have been totally fine.

@rgatan3 We havenā€™t tried an inactive SIM yet but think (hope?) that that should work as well.

@dave.drapac I have had success in following @nystrom method of obtaining the correct APN. This worked for two RV50xā€™s of mine.

+2 I just revived two bricked RV50x s using this method. This saved me a pile of money! Thanks @nystrom !

Thank you @nystrom. Iā€™ll be giving it a try. Keeping my finger crossed.

I guess the SIM card has to be active?

We actually had success without activating the SIM. Another method that seems to work is to switch firmware on the Advanced tab from whatever is in use to an alternate, and then back.

Thank you for the suggestions. I tried replacing the AT&T SIM card with a Verizon and back but it didnā€™t seem to work. Iā€™ll try switching firmware like you suggest.
Thanks againā€¦

Hello again! Also did you update the ALEOS Software or the Radio Module Firmware, or both. Can you tell me where I can find the Firmware for the MC7455? Not sure why Iā€™m having such trouble.
Thanks for your help>

I try to upgrade and I get a message saying---- Please select firmware for MC7455???

Uploaded Verizon firmware then uploaded the At&T firmware againā€¦No luck.
Rebooted with a Verizon card and then again with the AT&T cardā€¦No luck.

I had the same issue with 2 RV50X modems using Verizon sim cards. I resolved the issue by doing the following:

  1. Hard reset modem (held reset button until flashing orange.)
  2. upgraded to latest firmware
  3. reboot
  4. installed and activated GENERIC radio firmware
  5. reboot
  6. changed override APN to so01.VZWSTATIC
  7. reboot

When I installed the verizon radio firmware first, I had the same issues in this thread. I was only able to resolve by following steps 1-6 above.
