Ubnt Nanostation Loco M2 - WDS link drops out after a few hours
I have a pair of Nanostation Loco M2 access points setup as a wireless bridge over a ~1300 foot (~400M) line of sight link.
I have had LEDE 17.01.3, 17.0.4 and OpenWrt SNAPSHOT r5499-575178e / LuCI Master (git-17.343.27587-8e6b1a6).

One is setup as a WDS AP and the other is setup as a WDS Client, after a few hours (4-12 hours?) the link drops out but still says that is connected (if I go to status it shows the other AP as connected but I cannot ping or do anything else across the link).
If I restart the wireless service on the client, the connection comes right back and all is well for a 4-12 hours.
Anyone have any suggestions on where to look? Below are the kernel and system logs for the time period in question:

I have the same behavior on a TP-LINK WDR3600 <-> TP-LINK CPE210 setup with WDS. Seems to be something with Atheros chipset. I also have a second WDR3600 and a Ralink WDS client which are rocksolid stable.

Bump, still seeing this in OpenWrt SNAPSHOT r5902-9c2ac19b03 / LuCI Master (git-18.021.64448-4dddecf), is there anything I can/should do to troubleshoot this, or should I just roll back to the stock firmware?

Same for me, feels like it got even worse the last 2 weeks. I already opened a Bug about these Kernel warnings without any success. Looks like WDS has to be considered "unstable" on ath9k with Lede installed.
