Here is the procedure to keep two different router on same network:
Note: Assume Router1 (R1) is located at ground floor and Router2 (R2) is located at first floor.
- Internet connection is connected to WAN port of R1.
- WAN port of R2 is unused.
R1 LAN settings are below:
- IP Address: 192.168.0.1/24
- Subnet Mask: 255.255.255.0
R2 LAN settings are below:
- IP Address: 192.168.0.2/24
- Subnet Mask: 255.255.255.0
- Gateway: 192.168.0.1
Steps:
- Step 1: Connect one end of a Ethernet cable to any one of R1 LAN ports and connect another end to any one of R2 LAN ports.
- Step 2: Turn on DHCP server on R1 and reboot
- Step 3: Make make space for static IPs in R1 For example, if DHCP range is 192.168.0.2-254, make it 192.168.0.100-254 so we can have 98 static IPs.
- Step 4: Turn on DHCP server on R2 and reboot
- Step 5: Disconnect anything from WAN and set WAN to dynamic in R2
- Step 6: Change LAN IP Address of R2 to 192.168.0.2/24
