Thanks for the reply!

I'd rather use the AX73 as my main since it's new and better speeds and such.

As of right now, I left the C7 in the box as a spare router. If i get any tip on how to get the 5ghz WDS going or TP-LINK change and let us make a router-router easy/onemesh network, ill use it. 

Hi  @JULIANODCO85 

May I know, when you try to scan Archer AX73’s Wi-Fi on Archer C7, can you see AX73's 5G Wi-Fi normally?

If you can see it but failed to connect to it, please try to change the security type to the same, or change it to no security:

If not, please check what channels the 5G bands of the two routers currently use? Try changing the channel to the same channel. The instructions for changing the channel are as follows:

Thank you.

C7 can scan the 5ghz AX73 wifi normally. I've set the same security options (WPA2-PSK(AES). I can't be without security cause it's a very populated area. Same with channels (tried all lower ones and left on 48) on my tests, 5ghz WDS still won't work, only the 2.4ghz.

It's funny cause 2.4ghz WDS works flawlessly, can access both routers on the network, every PC and device. 

Hi  @JULIANODCO85 

It seems that the 5Ghz WDS function of Archer C7 may be faulty. If you still need a device to wirelessly extend the network of the main router Archer AX73, I think you can consider adding a device that supports Easymesh, like Archer C6, Archer AX12. Because Archer AX73 currently supports Easymesh feature (please update to the latest version of the firmware).

Thank you.
