[RT-AC66U] Looking for information

[rmondegar]

Hello gentlemen,

I'm about to buy a brand new RT-AC66U, however, since I had bad experiences in the past, I'm doing some research first.
I don't mind paying a little more than the usual as long as the quality is the same as advertised, but since I'm also importing this, I would like to ask you guys:

- Does the router have any known issue, either with OFW or this Firmware ? I'm most interested in lower throughput, less coverage or loss of connection.
- Is it possible to use a script either in the OFW or this Firmware to setup the following QoS settings (as I had with DD-WRT):

I know it is possible to do this using DD-WRT, however, I had bad experience in the past with several routers performance in comparison to the OFW.

Thanks in advance,

Shameless bump. Really need some info.

With Asuswrt-Merlin you should be able to set up the QOS rules using the custom script support (or even custom config support, not sure how QOS is set up since I'm satisfied with the built in QOS support).

Note that the RT-AC68U is due soon... http://www.asus.com/News/RhRGRF9xiiVPIG1y

Thanks for the replies. Would be nice if someone could confirm that with asuswrt-merlin I could set up a custom script like that and that are no major issues, like rebooting router, lower througput in comparison to the stock or signal loss.

I'm about to buy a brand new RT-AC66U

As DanielCoffey said, you should consider to wait a little and then buy AC68U.

AC isn't even a finalized spec yet. Take a look at the threads here and draw your own conclusion on how many people are experiencing "major issues." Granted this is an experimental demographic, but even multi stream N routers are just barely settling in a nice, consistent groove right now. Signal levels are varying wildly right now (across multiple models) due to some lower level driver changes.
