Hi,

Yesterday I have just upgraded my Archer C6 router to the Archer C5400X because I wanted to have faster WDS speeds.

So now I have an Archer C5400X router connected to my main router (UPC Giga Connect Box) via WDS using 5GHz-1. The main router (UPC) is connected to the Internet. The WDS Wi-Fi channel is set to 36 so I have to use 5GHz-1.

Before I upgraded to the Archer C5400X I had an Archer C6 and it's WDS/WiFi settings were the same as in my new Archer C5400X and everything was working fine.

The problem I am facing is that when I enable WDS on my Archer C5400X on the 5GHz-1, the WDS connection works fine but the Wi-Fi 5GHz-1 does not work at all. The 5GHz-2 one works fine.

On my Archer C6 when I enable WDS on 5GHz the 5GHz WiFi works fine, the SSID appears on the list of available networks. But on the Archer C5400X when I enable WDS on 5GHz-1 the 5GHz-1 WiFi SSID do not appear on the list of available networks just like it is disabled or using WDS on 5GHz-1 excludes using the 5GHz-1 WiFi network.

My UPC Giga Connect Box configuration is the following:

IP: 192.168.0.1

WiFi 5GHz SSID: WiFi Bridge 5G

WiFi 5GHz channel: 36

My Archer C5400X configuration is the following:

IP: 192.168.0.2

WDS 5GHz-1 SSID: WiFi Bridge 5G

WiFi 5GHz-1 SSID: WiFi Clients 5G

So with the above configuration, when my Archer C5400X connects via WDS to the UPC Giga Connect Box via 5GHz-1 (SSID "WiFi Bridge 5G"), the WiFi 5GHz-1 with SSID "WiFi Clients 5G" does not work at all and do not appear on the list of available WiFi networks. If I just disable the WDS the 5GHz-1 "WiFi Clients 5G" works.

What I have tried:

- I have the newest firmware

- Flashed the firmware to the newest version

- Rebooted,restored factory defaults via interface and button

Please tell me if this is a bug in the firmware or my router is faulty.

Edit: the same happens if I switch WDS to 5GHz-2 -> then the 5GHz-2 WiFi does not work. It seems that enabling WDS on either the 5GHz-1 or 5GHz-2 prevents WiFi on this band from working. On my Archer C6 it does not do that, you can use WDS on the 5GHz and 5GHz WiFi at the same time :/
