I currently have a modem/router combo up in the front of the house. I have a guest house about 150 feet away that I currently have internet to via a cat6 cable ran which meets into a 4 port switch, then into the house into a 16 port switch which feeds internet to the house. Both switches are un-managed.
I need to add wireless capability to the house as well and built an outdoor router enclosure, took out the 4 port switch which was succumbing to being outside and plugged everything in. Internet in the back house was working fine. The issue was the devices in the back could not communicate to the front building with the current network. Oops, I realized that their configurations are different which is most likely why they couldn't communicate with each other.
Router 1 (which would act as DHCP) has a configuration of
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
With an IP address range in DHCP of 192.168.0.2 to 192.168.0.254
Router 2 is a TP-Link Archer C5
I am not entirely sure now how to configure router 2 to give both wireless access and LAN access to the back house that will allow both areas to access shared drives/resources on the network. My first idea was to change the IP address of the second router to an IP address that was in the same subnet and fell into the DHCP range of the first router ( a higher IP address that would not be assigned due to the amount of devices).
I wasn't even able to change that IP address due to the following error: Error code: 5008 WAN IP address and LAN IP address cannot be in a same subnet.
So at this point I am trying to figure out how to get this going from here. I attached a visual drawing of the network in a basic Visio drawing. https://imgur.com/a/AjOAY
I appreciate the help is filling in the gap I am just not seeing.
