Troubleshooting

MAC Address / Manufacturer is inaccurate/unknown

The program does an ARP lookup to determine the MAC address. This lookup can sometimes require admin-level permissions to retrieve accurate results. Try elevating your shell before execution.

Message "WARNING: No libpcap provider available ! pcap won't be used"

This is a missing dependency related to the ARP lookup. This is handled in the code, but you would get marginally faster/better results with this installed: npcap download

The accuracy of the devices found is low

I use a combination of ARP and Ping to determine if a device is online. This method drops in stability when used in many threads. Recommendations:

• Drop parallelism value (advanced dropdown)
• Use python > 3.10 im noticing threadpool improvements after this version
• Create a bug - I'm curious
