Model: Archer VR2100  
Hardware Version: V1
Firmware Version: 1.5.0 0.9.1 v009e.0 Build 210722 Rel.37847n

Hello I've two devices
Archer VR2100 acting as router/modem, providing Internet access and DHCP, with static IP 192.168.8.1
Archer C6 acting as router, providing wifi and lan connection with DHCP disabled, static IP 192.168.8.2 and WDS in RUN state SSID and MAC of VR2100 (via survey, with solid signal)

even though I am unable to ping 192.168.8.1 from C6 (and Internet connection is obviously not provided and network acts as different network). I've tried 2.4 Ghz only, 5 Ghz only, dual, WDS on on 5 Ghz, WDS on 2.4 Ghz. no matter what (yes, I checked password is correct, network type, channel is same) VR2100 does not list it as connected device, nor C6 pings VR2100.
C6 is V2 with 1.3.6 Build 20200902 rel.65591 and was working in this mode just fine with my former Huawei modem/router.

My current hypothesis is VR2100 does not server C6 connection requests (maybe firmwware bug? - I tried older firmwares with no success), but I don't know what to do with except replacing VR2100. Any ideas what to do / try?

PS. when I connect VR2100 and C6 via cable, it works fine, but I can not connect them that way in there desired positions (I need wi-fi WDS bridge connection).
Thank you for your suggestions.

@JohnCourtier 

Hi, what could be the IP address on the device when connecting to C6 when C6 WDS to 2100?

It is suggested that you could try the following suggestions:”

1.  As for the WDS mode, did you try all three, auto, WDS1, and WDS2?

2. Could you please try to set up a static route on the C6 to VR2100, such as

Thank you.

@TP-Link thank you for your suggestion. Unfortunately it did not resolve the issue.
ad1) WDS mode select box is no longer available on C6 (it is hidden and disabled input in html - no, adblock extension is not to blame here, I checked on multiple browser even with all extensions disabled). Anyways, I even tried to edit html to re-enable the input and send the form. I tried all three WDS mode options, none helped.
ad2) this static route did not help either, C6 was not able to ping 192.168.8.1 and after reboot I did not manage to log in to C6 from PC (ping was ok, but login requests were failing - PC had static IP configured, as DHCP was not working) no matter what and had to reset it and setup from scratch.

@TP-Link 
Oh I forgot to mention IP of PC connected to C6 is 192.168.8.66 - static IP as DHCP is not provided (VR2100 is DHCP and C6 does not connect there to provide VR2100 - PC connection)
