Thank you for posting this. I just checked my e-mail again and saw that mine did ship today also. I will have it tomorrow (1 day Prime shipping was $3.99).
Curious if the RT-N66U shipped from Amazon will have the latest, non-broken firmware? I'll report my findings.
As I posted when I first set my RT-N66U up, I guess I got lucky - I had no problems using the GUI (set to English language) to set up my 2.4 GHz and 5 GHz wifi and then upgrading the firmware via the Asus GUI without any special tricks or workarounds.
The only thing I noticed (minor detail) is that the firmware update progress indicator disappeared at one point and the screen never refreshed on its own. To be safe, I opened a NEW browser window and checked connectivity to the internet. I then left the original window (used to update the firmware) open a while to be safe in case there was anything still being updated (usually not the case once internet access is restored when upgrading the firmware but I was not going to take any chances).
I also love how fast updates take.
With the Amped I had to wait for it to reboot after almost every type of change if I recall correctly.
The Asus config screen is VERY quick to refresh after most GUI changes (better than the other routers I have owned).
The only things I think they should address:
1. I do not like the fact that WPS was enabled by default (given the exploit that was recently announced).
2. The guest network seemed to stay enabled after I changed the settings . It did not help that the screen is a bit confusing (initially only) since it says 'Enabled' instead of 'Enable', so I thought clicking would disable it when in fact it did the opposite. I think I had to disable it (click 'off') twice to get it to stick but since I only played with guest wifi once, I will give them the benefit of the doubt unless I can recreate it.
All in all this is by far the best performing / most full-featured router I have owned.
Unless something amazing is announced, I think I will stick with this for at least a few years (I say "think" rather than "know" because there is always a chance that the 'new technology' desire in me may succumb to some new high-end router with new technology next year, aside from 802.11ac which will probably not help with range and whose maximum speed is overkill considering both my current internet bandwidth and file copying needs - I don't spend too much time copying data over my network).
I honestly don't see myself getting a new router for a while now, other than at most possibly a second Asus RT-N66U as a spare, although I might wait a while to do so if I choose to go that route since there is a warranty).
