I have the RT-N66U and I am really loosing patience with ASUS and am willing to try your build but have some questions before i make the switch. Is there a problem with the 32K NVram if I add alot of mac adresses and QOS rules? With your build are guest networks possible? Can QOS and wireless filter be applied only to specific devices and/or ip ranges on the network regardless if they are wired, wireless or guest wireless? I have roommates that I give internet too but they forget and leave their computer on downloading torrents and I would like to limit their bandwidth and also limit the devices they add to my network. I have a VOIP phone adapter connected and whenever I see high amount of downloading from them my voice quality is crap. Once i give them the WiFi password they can add any device to the network and i would like to stop that too so they wont give their friends access to my network. It seems that ASUS enabled the possibility of having all these extra guest networks but they totally separated them from any kind of manual tweaking. If this FW cannot help me can you suggest another way I can do this? I have a computer running IpCop that is a firewall computer but I would rather not use that if I can make this router filter macs on guest networks.
