Scanning a network BLIIoT 4G Edge Router

Installing and Using OpenWrt
1

I have multiple installations with multiple routers dotted around the property. They all have WWAN connection to the same WiFi network and there own 4g backup connections. I have had a few problems in the past and it's happening again with devices going offline in remoteit. This largely results in site visits around the country but i have just realised if i can ssh into one router i can then reach the others on the same wifi network to reboot them or reinstall remote it.

Is there a way to perform a network scan and list the IP addresses of all the routers that are on the wifi network even though they show offline in remoteit?

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:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. 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.

but aside from the fact that it's probably a vendor specific build is there a putty command to scan the network for other lan clients, or a plugin that may work to perform that task?

depends on what you mean by scan.

yes that's the sort of thing i'm looking for. I'll try installing fping.

thanks for your help!
