Hi，thanks for posting question on our community.

May I confirm that your network topology is Archer AX73--eero router (AP mode) or eero router(bridge)---AX73? I got a little confused according to your description.

Hi,

I have my AX73 as the router and the eero is in bridge mode.

  @Marvin_S 

I have the modem details as well if that's of use.

Modem (ADTRAN SDX 621i) -> (WAN port) TP Link AX73 Router (LAN) -> eero Pro 6e (in bridge mode)

Hi, thanks for your detailed information.

As I understand it, I will set up eero Pro 6e router as Access Point mode instead of bridge mode.

Hi,

I think for the eero AP mode is bridge mode. I've attached a couple of screenshots of the options.

Make sure you give them different DCHP addies as well, so change at least one of them preferably both of them from the 192.168.0.1 etc to say 192.168.55.01 & 192.168.55.02 for instance (use your own numbers not my examples), make sure the pool numbers aren't in the connected devices pool either for connected clients so set your range to be outside of the router/s dchp pool.
