Hey everyone,
I’ve been using Lansweeper to scan and manage our network inventory, but I’ve noticed that some devices aren’t being detected during scans. 😑 These missing devices include a mix of printers, IoT devices, and a few workstations that should be reachable. I’ve checked my network configuration, ensured that the devices are powered on and connected, and even manually added some IP ranges to the scan settings, but the issue persists.🤔

I’m wondering if there’s something I might be overlooking—could this be related to firewall settings, SNMP configurations, or maybe even a specific protocol that needs to be enabled? I’ve also tried running different scan types (IP range, Active Directory, etc.), but the results are inconsistent. Is there a recommended troubleshooting method to ensure Lansweeper discovers all devices on a network properly?🤔      Checked   https://community.lansweeper.com/t5/general-discussions/devices-not-showing-up-anywhere/td-p/49919-devops resources, and found it quite informative.

If anyone has encountered a similar issue and found a fix, I’d love to hear about it! Any advice on refining scan settings, adjusting credentials, or using alternative detection methods would be really helpful.  🙂

 

 

Thank you !!

Hey catherine - I like to use the device tester:  https://community.lansweeper.com/t5/troubleshooting-scanning-issues/troubleshoot-device-scanning-iss...

it's on your on-prem Lansweeper scan server - run it from the server and test things out - it shows you the logs.

Hello Catherine, 

For the most common scanning errors, please have a look at our KB articles. 

You will find solutions there to the common scanning issue. Also, on how to add credentials to scanning ranges and what the requirements are. 

If you get no assets at all created the article below is a good one to start with.
