TP-LINK routers use either tplinklogin.net or tplinkswifi.net. The company has lost control of the domain, which is now owned by an anonymous entity. Another domain, tplinkextender.net, is also for sale. This means that when owners of TP-Link routers try to access their routers using the domain they still own, they will be directed somewhere other than the router login page. This is not a security breach, however, while this is a security issue.”]
