Snoop's Take

The TP-Link AX1800 WiFi 6 Router V4 (Archer AX21) is a dual-band wireless router that leverages the latest WiFi 6 technology to deliver speeds up to 1.8 Gbps. It is designed to handle streaming, gaming, and secure connections while supporting VPN servers and smart home integrations. Consumer feedback highlights the router’s reliable day-to-day performance, with users noting remarks like “never had a problem with.” However, while many appreciate its plug-and-play reliability and responsive technical support, others grumble about invasive features such as the Home Shield service and limitations with mesh networking support. Comments range from unequivocal support—“literally 0 issues with them, rock solid devices”—to criticisms about performance under heavy IoT loads. Overall, the router is recommended for home environments focused on entertainment and smart connectivity, though prospective buyers should be aware of its quirks with advanced security features and mesh limitations.

Never had a problem with.

Positive Feedback

Here is the kicker though, I have the Avira / Home Shield services completely turned off... The router doesn't care, and sends ALL your traffic to be "analyzed" anyhow.
