I use the built in Cellular modem of my B One 5G and a secondary cellular modem connected to a physical WAN port. For the built in cellular modem, I have it set to SmartCheck. I am unable to choose this option for any other WAN connections. Is there a reason this option isn’t available? Can you add this option if it does indeed save data? I can’t be the only one doing this.
Hi…
About Smartcheck
SmartCheck is a health check method used by Peplink routers to limit data usage on cellular connections. It works by sending an ICMP ping request to a target host if it doesn’t receive a response within 10 seconds.
How it works
- If the router is using a cellular WAN connection, it will use SmartCheck.
- If the router doesn’t receive a response from the target host within 10 seconds, it will send an ICMP ping request.
- If necessary, the router will send pings to the DNS servers on the cellular WAN.
Why it’s useful
SmartCheck is useful for limiting data usage on cellular connections.
Conclusion:
" The SmartCheck algorithm is specifically for Cellular connections and was added to reduce cellular data usage. "
Right. So is this possible?
I’ve run into the same thing with my setup, where the SmartCheck option is only available for the built-in modem. I think it’s because it’s tied directly to the firmware of the main cellular connection, while other WAN ports might not support it. I’ve tried using a secondary modem myself, and no matter what I did, I couldn’t get that feature working with it. If data savings are what you’re after, it might be worth looking into some manual tweaks or third-party tools for your secondary modem, but I haven’t found a good solution for that specific feature yet.
