Hello everyone, 

I have a TL-MR6400 v5 (2.4ghz 4G LTE router) setup as my main router (with internet from SIM).

I have an Archer C6 v2, setup as WDS Bridge on 2.4 ghz band (using user guide pdf manual, also same info from www.tp-link.com/support/faq/1555/)

        LAN IP set to 192.168.1.2 same subnet as the root router (192.168.1.1). Also outside DHCP range IPs from root router.

        DHCP is set to disabled.

        WDS status shows Run.

But WDS is not working at all.

There is no internet shared from the root router, when trying to connect to either wi-fi or lan ports (cable) on the extended router (Archer C6 v2).

What is it I am missing to get it working?

The channel from Wi-fi Properties on the extended router (Archer C6 v2) is grayed out, probably because it auto configures it to be the same with the channel from the root router 2.4ghz wi-fi.

Passwords for wi-fi on both routers are different. Do they have to have the same? (I have not tried that yet, as I am not currently at home

I am aware WDS bridging only requires the WDS setting on either the root router or the extended router, on either 2.4GHz or 5GHz; No need to setup this up on both sides or bands.

As far as I know the main router does not support WDS bridging (cannot be used as wds bridge)

WDS can be setup and run correctly ony if it is supported by both routers (and setup, enabled on the router chosen as bridge)?

Or it suffices to be supported by the extended router only?

Thank you.
