3.2 Gather Necessary Tools

• Ethernet cable – Do NOT upgrade over Wi-Fi; a single dropout can corrupt the flash.

• TFTP server software (e.g., SolarWinds TFTP Free, Pumpkin TFTP) – if web upgrade fails.
• Uninterrupted power supply (UPS) – Power loss during upgrade is catastrophic.

• Your ISP pushes a mandatory update to fix a known bug (e.g., IPv6 prefix drop, WiFi 5 GHz disconnects).
• You need a specific feature from a newer release (e.g., bridge mode improvements).
• You are experiencing a documented vulnerability (e.g., CVE-2021-3427).
