Error 99 on 3g modem

Hi All,

I am trying to dial up on a Huawei E173 3g modem and I recieve an error 99. I can attach this USB connection to my laptop and it works fine, the APN settings etc are very simple.

Any idea’s as to what error 99 means?

Hi There,

Thank you for your inquiry. Just to cover some of the Basics, please confirm/update the firmware on the Balance to the latest release and test again. You can verify firmware with the Balance’s built in firmware checker under System > Firmware > Firmware update.

If there are still issues after confirming/updating firmware, go ahead and open a support ticket at the following link-

In addition, please capture a diagnostic report from the Balance while the issues are occurring but before rebooting to preserve the Event Logs for review. This will also get us a copy of your configuration file for the team to review and see what, if any, changes are needed.

Instructions on capturing the report of course can be found at the following link:

Keep us posted and we can go from there.

Best Regards,


The Peplink Team

The upgrade of the firmware fixed this! Thanks for the help!
