I have fibocom modem FM190W-GL on m.2 slot of router ZBT z8102ax (eMMC, OpenWrt 21.02-SNAPSHOT 24.0810_155716), the modem doesn't go online. Router's driver detect modem and SIM is registered. Also AT commands are working. Any help to solve the issue?
thanks
start by installing proper openwrt (eMMC version might not be supported though), you're currently running a vendor SDK.
if you can't, ask the people who created the image (ZBT ?).
It appears you are using firmware that is not from the official OpenWrt project.
When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.
You may find that the best options are:
- Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
- Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
- Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).
If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.
@frollic thanks for your reply. I can't install official openwrt firmware since the eMMC version is still not supported. I asked many people here and on github to help in supporting it:
- https://github.com/Ysurac/openmptcprouter/discussions/3698#discussioncomment-12533478
- https://github.com/4IceG/ZBT-Z8102AX-M2/issues/7#issuecomment-2754876324
- and some email to Daniel Golle, etc
As far as I know the closest model is still unsupported as well:
here are some info about my situation
