This is a great third party firmware for ASUS routers. I have used it and the features are plentiful and you can actually set each device to connect its own way. It is a great way to explore alternative firmwares for routers that just do not offer enough.

Just had to say that I love this firmware. My Asus RT-AX68U runs great with it. I've got my IoT's on a different VPN server than my phone which is on a different server than my Linux PC. The options for control are fantastic and wouldn't want another router without my Merlin firmware. I just installed 3004.388.12_2 and it's been great. Highly recommend.

This has been excellent! I will note that if anyone is trying this with the ASUS RT-BE92U, that I am having an issue where WiFi networks aren't able to access my Plex servers. Not sure if the developer reads these posts (and apologies if this is the wrong place to post this), but I reverted back to the prior firmware for now. As further endors****t, I have used the ASUSwrt-Merlin firmware across 3 different ASUS router generations (Wifi 5,6 and now 7) and it has been truly amazing functionality and stability wise.

Love Asuswrt-Merlin! It is a must for any ASUS router. I have been using it for years now on all of my ASUS routers, and the features unlocked by this custom firmware are amazing while retaining the original UI and features the router ships with. Thanks for all the great work!
