Historically, TP-Link releases major updates for the C6 every 8–12 months. The 2025 release is a major "security and stability" drop. Expect the next one (1.4.0) around Q1 2026.
Crucial: Before downloading any firmware, flip your router over and check the label. You must match the firmware to your Hardware Version (e.g., V2, V3, V4, V5).

Important for 2025: TP-Link has ended firmware support for Hardware Version V1 as of Q4 2024. If you own a V1 unit, consider upgrading your hardware for security reasons.
Many users complained about the 5GHz Wi-Fi band randomly dropping for 10–15 seconds on older firmware (version 1.3.5 and below). TP-Link engineers confirmed this was due to a DFS (Dynamic Frequency Selection) channel switching glitch. The 2025 new firmware introduces a refined channel selection algorithm, completely eliminating that micro-disconnect issue.
