I have an Archer C7, to which I have already flashed OpenWRT.
avoid any routers with Broadcom or Qualcomm
Noted! I assume that the Archer C7 is an exception to that? It has a Qualcomm chip afaik. But, yeah, the AX73 is Broadcom.
Use the AX73 as your primary and the OpenWRT one as the repeater node and you’re set.
Is that not what WDS, or 802.11s is (I’m not arguing, I am simply unaware, and I would appreciate correction!)? I’ve tried setting this up a number of ways – all to no avail. I haven’t been able to identify exactly where the problem lies in the setup, as I am not knowledgeable enough about network administration yet. The Archer C7 is able to connect to the AX73 just fine, but any device connected to the Archer C7 is unable to reach the AX73. Would you be able to provide me with any instructions, or recommendations for guides to set up what you are describing? I’m missing some important set up step, or I’m improperly configuring something.
If Ethernet between the 2 is viable, go with that instead
I would like to try and set it up over a wireless link.
