Hi,

What is the hardware version of the 2 Archer C3150? 

Meanwhile, the distance between the 2 houses are about 600ft, compared to the indoor router and configure it as range extender to extend the wifi range, the outdoor devices can be used to build up a point to point connection will be better. Like the CPE device.

Good day. 

Hi,

You can use the engenius station 5 to extend the wifi range, like C3150--engenius station 5-a )))(((engenius station 5-B--c3150. 

While for the engenius station 5, we are not familiar with it, it is suggested to contacted their tech support to configure them and build up a point to point connection.

Nice day. 

Hi,

Hi, I thought you use the enstation5 to builb up a  point to point connection and make it work as the internet source, so the 2nd C3150 can connect the enstation5 on House 2 to get internet. Just like the network topology I mentioned in my last reply.

The Archer C3150 does not support WDS function, that means they cannot connect to each other via wireless. 

Meanwhile, below is the instruction to configure the 2nd C3150 as access point. In this way, the 2nd C3150 need connect to the 1st  C3150 or other internet source to get internet by wired cable.
