-T 1 forces DLT_EN10MB (Ethernet). For raw 802.11, use -T 105 .
PCAP (Packet Capture) is a file format used to store network traffic captures. It allows network administrators and developers to capture and analyze network traffic for troubleshooting, debugging, and security analysis purposes. PCAP files contain raw network packets, including headers and payloads, which can be analyzed using various tools. -pcap network type 276 unknown or unsupported-

Use xxd or a custom script to dump packet bytes, then rebuild: It allows network administrators and developers to capture
A security team was auditing a fleet of medical IoT devices (insulin pumps) that communicated via 802.15.4 (ZigBee). They captured traffic using a dedicated USB dongle which wrote pcap files with DLT 276 (mapped to DLT_IEEE802_15_4_TAP ). When they transferred the file to their central Linux analysis server (running RHEL 7 with an older libpcap), they received the error:
