: Models like the Raspberry Pi 2 (Model B), Raspberry Pi 3, and Raspberry Pi Zero 2 W utilize ARMv7-compliant cores when running 32-bit operating systems (e.g., Raspberry Pi OS 32-bit).
But software versions matter. While desktop users might be running dhcpcd-9.x or 10.x , the unsung hero of the ARMv7l (32-bit ARM hard-float) world remains a specific, battle-tested release: .
The identifier "dhcpcd-6.8.2-armv7l" refers to a specific version and build of the DHCP client daemon (dhcpcd) dhcpcd-6.8.2-armv7l
The primary configuration file controlling interface behavior. /usr/libexec/dhcpcd-run-hooks
In headless IoT applications, a missing network cable can cause dhcpcd to block the boot sequence for up to 60 seconds while searching for a carrier or a DHCP server.

The daemon does not trigger wpa_supplicant automatically (unlike dhcpcd 9.x with built-in wpa_support). You start wpa_supplicant first, then dhcpcd -b wlan0 .

sudo apt install dhcpcd

Even a stable version has quirks. Here’s what engineers encounter:

While modern stacks force dual-stack, 6.8.2 allows clean separation. You can disable IPv6 entirely ( -4 flag) to save memory on a headless sensor node.
