Troubleshooting

MAC Address / Manufacturer is inaccurate or unknown

LANscape does an ARP lookup to determine MAC addresses. This can require elevated permissions to get accurate results — try running your shell as admin.

Scan accuracy seems low

The scanner uses a combination of ARP, ICMP, and port probing to find devices. If results aren't great out of the box:

• Tweak the scan configuration preset (accessible from the gear icon)
• Set up ARP lookup properly — see ARP issues
• Open an issue if something still seems off

Something else
