FAQ

TP-Link router questions

Why do I see a private IP on the TP-Link WAN page?

That usually means another device or your ISP is performing NAT upstream. The checker result and your network layout can help narrow it down.

Could the TP-Link app show a different value than the web interface?

Some apps simplify status information. If values differ, prefer the detailed router status page and confirm the connection mode.
