Is there any tweaks for the ac66u/r? I have firmware version 3.0.0.4.376_1123 as I have not seen a lot of tweaks/tweak guides for this router been released/updated in a while. I don't care what type of tweaks they are if it helps the speed, WiFi, security, etc I would want them listed. Even if the tweaks are just generic and not just for this router model or Asus firmware list them also. **BUT do not post any tweaks that require me to install the Asuswrt-Merlin firmware ONLY tweaks that work with the Asus official firmware**
