I am looking for a recommendation for my network configuration that includes wireless AC. I am not a networking expert, so please indicate where I should have (un)managed switches, router, firewall, AP, etc. Recommended network devices can be combination devices as appropriate.
Currently I have a wireless N router with 4 gigabit ethernet ports that I was using for my wireless that needs to be replaced. If the replacement AP/router suggestion is a similar device, I would prefer that it have DD-WRT support.
Devices:
High internet priority
Server
My main machine
High intranet priority
HTPC
NAS
Low priority
Various wireless devices
Guest wireless devices
Thanks in advance for your help.
