Lansweeper finds your network devices, but unfortunately, they are discovered as a different device type.
Lansweeper will use all the information it can retrieve from your devices during scanning to determine the device type.
Ideally, network devices are scanned with the SNMP protocol. If SNMP is unavailable on the given devices, some information can be retrieved through other protocols such as SSH, HTTPS, and more.
For instance, if your device is detected as a Linux device, it most likely was not scanned using SNMP but SSH. If a printer or scanner shows up as a web server, likely it was scanned through HTTP instead of SNMP.
How can you solve this issue?
Make sure Lansweeper can access the information it needs to determine the correct device type.
