How to wring out problem: AC68U mesh node drops

[kentek]

I have 2 RT-AC68U in a mesh set up. The Primary router is connected to FIOS modem via Ethernet. Both Asus routers have V 385.15 firmware. Performance is very good. Only issue is that the Mesh Node goes to sleep every once in a while requiring either a 3-4 minute wait until is comes back or a node reboot. The Mesh node is on WIFI and about 80 feet away from Primary.

The Primary-Router never seems to have a problem. Not a lot of traffic as I am only user. Drops sometime while on computer or using Roku for streaming.
Looking for something obvious but don't see anything.

Seems like you are using stock Asus firmware? This is the RMerlin firmware forum.

@OzarkEdge's notes may help with your AiMesh issue.

https://www.snbforums.com/threads/o...-supported-products.44375/page-14#post-381537

I suggest flashing both routers to RMerlin 384.16_0 instead.

The link in my signature below may also help to get your routers/network stable again.

Only issue is that the Mesh Node goes to sleep every once in a while requiring either a 3-4 minute wait until is comes back or a node reboot. The Mesh node is on WIFI and about 80 feet away from Primary.

Inspect the two wireless backhaul entries in the Wireless Log. 80' may be too far/weak for 68Us. You could move them to say 40' to see if the problem stops.

I have 2 RT-AC68U in a mesh set up. The Primary router is connected to FIOS modem via Ethernet. Both Asus routers have V 385.15 firmware. Performance is very good.

The Primary-Router never seems to have a problem. Not a lot of traffic as I am only user. Drops sometime while on computer or using Roku for streaming.
Looking for something obvious but don't see anything.

No, I have ASUSMerlin installed on both devices: 384.15. I have now updated to 384.16. Both routers rebooted.
Thanks for letting me know of newer version. We'll see if it make a difference.
The issue could be the crappy FIOS modem/router on the other end.
