HWIC-3G-HSPA UP/DOWN

[missengineer]

Hello,

I have a problem about HWIC-3G-HSPA card.Line protocol is becoming always up/down and there is message on screen "Mailbox msg transmit failure".

Is there any opinion about failure and how can I solve this issue? 

I am sharing soma screenshots from config.

Thank you

This is the Wi-Fi forum, typically we can't help you much here. 

What I can see from the log, your HWIC module is flapping down and up, which causes various other issues. 

Have you tried a reboot?

Is the software and maybe HWIC firmware up to date?

Do you have enough signal strength where this device stands?

Maybe you need to reseat the module and sim card.

Dear all,

Maybe someone need the answer. Card was fail. I changed it and then problem solved.
