OK, this is indeed a general question (not a "please tell me which router to buy" question). Moving from network to network, I tend to notice different degrees/levels of service at the "handshake" point of joining the network. In the past, I have put most of this behavior down to the DHCP server IP provisioning/CPU speed etc in the gateway router, but I'm curious... where do "excellent" access points excel? Eg. if I were to run Tomato on a sufficiently fast router for DHCP/routing, what gains (beside signal strength) would enterprise access points provide (eg. ubiquti/mikrotik/engenius/cisco)? much appreciated!
