I‘m using Ubiquiti EdgeRouter X with LEDE Reboot 17.01.2 r3435-65eec8bd5f / LuCI lede-17.01 branch (git-17.152.82987-7f6fc16)
. The firmware is downloaded from lede download page.
The router's LAN ports are connected to a desktop and an access point(DAP-1665). Everything works fine but the connction between the router and the AP always got weird reset several times per day. The Desktop has no problem connecting with the router. I tried to replace the AP with other model(EX6100), problem remains.
I paste the kernel log, take a look at the end of the log, port 1 is linked to the AP. Any help is appreciated.
