I just picked up this router and I am impressed with the performance so far, but it is missing what I consider to be a fundamental feature: the ability to set a domain name for DHCP clients. Setting a domain name allows clients to easily find each other on the network using names rather than IP addresses. It looks like older TP-Link routers had this option, but it is missing in this one.
