Hello @A2Sumie 

Thank you very much for suggesting the idea of disabling the remote Tether access to the wireless routers. This idea will be reviewed for consideration.

I want to point out first that remote management or remote access is one of the important features for Tether management with a registered TP-Link Cloud account, which allows you to manage and access your router when you are not home, and you could enjoy some cloud-based functions including online upgrade, TP-LINK DDNS, etc.

At TP-Link, customer security comes first. We work diligently to ensure that our products include the highest level of security features, with firmware and hardware that protect customers and their devices from the latest threats. We also recommend you visit the following blog to review all the settings on your router as well as on your network to be sure that you are secured:
