Quick answer
Current answer
If your TP-Link Ethernet is not working while Wi-Fi is fine, or your Wi-Fi has stopped working while your wired connection is unaffected, the cause is usually specific to that connection type.

Scope & boundaries
- Applies when
- Use when: - a wired client reaches the internet through the same home router/network; - wireless clients cannot join or cannot obtain usable connectivity through Wi‑Fi.
- Does not apply when
- Excluded when: both Ethernet and Wi‑Fi lack internet → upstream/no-internet branch; only one Wi‑Fi client is affected while others work → device-specific branch; the user is comparing speed rather than availability → A1-25..
