I think my newly purchased RT-AC66U B1 is defective. Here is my story.

I bought it for purpose of setting up Aimesh in my home. Wanted to set it as a node link to my main router which is a RT-AC68U. I had upgraded both routers to latest firmware which is Version 3.0.0.4.384.81351 . Then did a factory reset to RT-AC66U before configuring it as a node. After that search the node from my RT-AC68U main router and successfully linked them up. Placed the RT-AC66U on the 1st floor almost directly above the main router on ground floor. That's when my problem start.

I noticed my node router (RT-AC66U) will frequently goes offline and online again. This will happen many times within an hour. I tracked this abnormality thru my PC which is connected by wire to the lan port of the node. At first I thought it could be the settings in my main router. I googled around and follow some of the advice in forums like snbforums. Even though after I changed and tried different settings, the constant offline and online still happening to my node.

After few days of frustration with failure in getting a stable Aimesh system, I decided to try something different by configuring the RT-AC66U B1 as a repeater utilizing the 5GHz wifi signal. This is when I realized the RT-AC66U as a repeater will also constantly disconnect and reconnect back to my main router. I suspect the unit I bought is a lemon.

ASUSmy or SIFUS here got any advice for me?

Ok will try your suggestion and report back later.

Based on your suggestion, i have this result from my phone speedtest. Doesn't seem to be weak signal.

Did the factory reset and reconfigure my RT-AC68U. Also placed my node RT-AC66U at a location which has better 5GHz wifi signal from main router as per @Blacktubi advice. The issue of constant offline and online to my node still persist.

Signal strength of connection as shown


System log attached


Any advice?

I will next try out your suggestion.

I replaced my existing main router RT-AC68U with the RT-AC66U B1. Running solely as main router with latest firmware 3.0.0.4.384_81351, I discovered that both 2.4GHz and 5GHGz wifi signal will occasionally disappear and appear again causing my clients to log out and log in again. The led lights on the router was up all the time when the wifi signal went off and on again.

The system log as attached


I thought the latest firmware could be buggy. So I follow @blacktubi advice and downgrade to firmware 3.0.0.4.384.45717. Did the whole hard reset and reconfigure again the RT-AC66U as main router. Again the same symptom of the wifi signal disappearing and later appearing again. Led lights were constantly on when the issue happens.

The system log of the router with older firmware as attached


I suspect the router is definitely having hardware issues. Can I get a replacement unit?


Thanks for the suggestions and help. But all those method didn't work. I suspect the unit is a lemon.

I'm staying in PJ Selangor. Where is the nearest service center i can send to?

Btw i bought online and received the RT-AC66U B1 on 15/11/19. I haven't register the product for warranty yet. Do i need to register?

This evening lightning strike the unifi pole behind my house. My unifi BTU display light went dead. I suspect it must have burnt the unit. Have reported to unifi technical.

Later I found out that my AC66U B1 which I bought less than 3 years ago also went dead with no led display lights. Can anyone confirm is warranty covered for lightning strike?

I am also having this same issue when I login to the Asus app. I'm running 2 RT-AC68 on latest AImesh firmware.

Can @Asusmy explain?
