I've try to install Tomato USB (last release) on my new rt-n66u but always the same problem occur.
The wan port can't receive an IP from my ISP (Cablecom (swiss cable operator)).
If i connect the asus with the stock firmware, no problem to get an ip, no probem with Merlin…
But if i install Tomato or dd-wrt, impossible to get an IP from the public network, and if i plug the wan wire on my local network, the IP come without problem.
Any idea ?
