Connected a new EERO to existing router using the same UN & PW, printer not working

[Trojan123]

Purchased a new EERO device to improve total house WIFI; all existing devices have synched up to the EERO mesh system except my HP 8710. I did use the same PW and User name and the existing router which was recommended but now appears to be the issue? When I unplug the EERO from the main source printer connects and prints. Thank you.

@Trojan123, Welcome to the HP Support Community!

The printer has to be connected directly to the wireless modem/router. It may not work when connected to any type of extenders. You may have to contact your internet service provider to check the configuration and connect the printer on the network.

The routers are probably not configured in bridge mode.  This likely is a double NAT issue which means multiple routers are handing out IP addresses and causes a conflict. Bridge mode means the router acts as purely an access point and not a router.
