As an experiment, I tried connecting to my C2600 AP as a (non-WPS) client using IPQ4019 radio.
It seems to be working fine.
I think this is likely the same bug described in FS#2286 and in another forum thread here. If it is, I've also been able to solve it in a local build using the patch that @ratking posted above.

Comments on the PR, if you can confirm testing and resolution, might speed core-dev examination and acceptance
I can also confirm that the updated kernel patch fixes it.
Apparently something has changed in the kernel data structures so that the previous OpenWrt version of the patch no longer works.
I confirm same problem , tested with WR1200JS and XIAOMI R3G:
with one box openwrt 4.14.102 and the other box in 4.14.121 no problem
with openwrt 4.14.121 and 2 * box i have this in WDS connection:
[ 96.503771] wlan1: send auth to d4:5f:25:eb:09:82 (try 1/3)

[ 101.312913] wlan1: deauthenticated from d4:5f:25:eb:09:82 (Reason: 2=PREV_AUTH_NOT_VALID)
I'll check it asap.
Fixes are merged into my staging tree. (master & 18.06 branches)
Could someone please build/test it and report back?
Thanks all

I don't have the time and attention to get things set up so I can do a build right now, but if someone builds a firmware with the patched kernel for the ea8300 and shares it I can flash it and report back.
The @xback build worked. Test system is a MTC WR1201 (MT7621 / MT7602 based) tested on 2 GHz.

1 - git clone … openwrt.git
2 - scripts/feeds update -a & install -a
3 - get xback-9dd6b51.tar.gz , extract & overwrite openwrt forder
4 - compilation with my old .config for WR1200JS
update firmware ( 2 * WR1200JS master and client WDS ) and no problem exactly as with x-wrt firmware
this patch solved part of the problem, without it the devices would associate and drop, now they stay associated but still no data pass through. built r10011. AP side log, there are still key problems:

interesting thing is that i was able to bridge Archer C7 v1's 5GHz using tp-link firmware without any problems even before applied this patch
Which hardware is this? OpenWrt / ath10k will not work on Archer C7v1. That first version of the chip has silicon bugs that the developers were unwilling to work around, so they abandoned it.
The bridge patch only affects clients. The unpatched kernel still worked on APs.
While dusty memories, I still recall being very happy that I didn't buy a C7v1 when they were introduced because of the lack of open-source driver support. As far as I know, the C7V1's chip revision still isn't (and never will be) supported for 5 GHz.
Litebeam AC Gen2, Archer was running tp-link firmware when the WDS bridge was established with one of these.
Set log_level to 0 on the AP there may be more information.
It looks like this is an ath10k bug in AP mode that doesn't belong in this thread.
got it working, the issue was introduced with
[PATCH v3] {nl,mac}80211: allow 4addr AP operation on crypto controlled devices
reverting this patch to v1 restored connectivity

Hey guys,
i got a WR841n V5 witch I use to repeat multiple SSIDs but got the same error as called above. Someone could give me a hint how to install the "fix" ?
Im On OpenWrt 18.06.5, r7897-9d401013fc
