Problem:

I upgrade my router from some years old dd-wrt to LEDE. "It works" and both the throughput and latency are vastly superior. However, it disconnect every couple hours for 2 minutes. Both my phone and my thinkpad are affected, so it is not a suddent regression in the client side. The old firmware showed no such interruption and could run a single connection TCP for months. At first, all packets stop being received and all sent timeout. After a while NetworkManager drop the (dead) Wifi conenction. Restarting networkmanager doesn't restore the connection, only time does. The encryption and channel are the same as before.

Info:

Hostname LEDE
Model D-Link DIR-615 rev. I1
Firmware Version LEDE Reboot 17.01.0 r3205-59508e3 / LuCI lede-17.01 branch (git-17.051.53299-a100738)
Kernel Version 4.4.50

SSHed into the rounter show nothing interesting in dmesg or the logs.

dmesg (client side)

What should I do to further debug this? I can build new images if necessary.

After a few days, I can see that WAN also disconnect randomly for a while. The ram usage never reach critical level (~22% free when it happen)
