Reflecting Asus-Merlin would cost your wireless router to lose AiMesh feature, however, Merlin retains the AiProtection which a major advantage with Merlin Firmware.

ASUS affirmed their confinement to providing the best to their end-user as, all of their products, constantly receiving software support for a specific amount of time, which usually hovers in between 5 to 6 years. When it comes to networking, ASUS marks the first position here due to their confinement to providing constant firmware update even for their older models like RT-AC68U.

But you should know that the Asus-Merlin only supports dual-band AC routers starting from AC66U_B1 to the top. And even if you are using the lower-end models (single-band wireless routers) for your internet subscription below than 100Mbps, you will still receive firmware updates from ASUS.  the sure thing is you will be notified if your wireless router model has reached its EOL status. We hope the above article helped you to install Merlin Firmware on Asus RT AC86u and to tweak your internet connection with an ease.
