How to set static ip address on my second router connected to first router?

Question

I have connected my second router to first router and I want to disable dhcp server on the second router and set static ip address on it. However I am new to all these things.
I have read that if I disable dhcp server, I have to set static ip address, else the router will lose its ip address and I won t be able to access it later.
What I read about some articles, they say that I have to set static ip address that is outside the range of the first router ip address. How do I determine this "outside the range of first router ip address"?
My first router ip address is 192.168.1.1 and the second router ip address is 192.168.0.1. subnet mask 255.255.255.0. Both are default addresses.

Answer 1

If the second router has DHCP disabled, it should be wired using the LAN ports only, not the WAN/Internet port. All computers should still get a DHCP from the first router. However, you should set the second router with its own static LAN IP address, so you can still get to it with your PC. I've described chaining two routers as one network before:

The range of the DHCP can be seen in the first router admin pages for the DHCP server. Usually it is a range of IP addresses, but some routers use all of it (192,168.1.2 to 192.168.1.254). That is not needed. Set it to a smaller range and "save" the settings. For example, set it to 192.168.1.100 to 192.168.1.199.

Then, connect to second router via a wired connection, and set the router IP to 192.168.1.2 (for example). Set the same DNS, gateway (these first two may not be needed or used, but no harm setting them) and netmask as any PC on the first router get from DHCP (copy those settings manually to second router). The second router must be in the same subnet (192.168.1.x) as the first if used as a switch/AP only. Having a router set to 192.168.0.1 means it will not see the first router because you are in a separate network.

Answer 2

You do not want to disable DHCP on the second router as this DHCP assigns IP addresses to downstream devices (computers).

You need to set the upstream IP address of the second router to the same network address of the downstream side of the first router, preferably outside the first router's DHCP range.

If you want to have 2 LANs, do what Steve is suggesting. If you want only 1 LAN with everyone it, follow the directions below...



1. On R1, change the DHCP starting IP address from .2 to .20 -- giving you a small group of static IPs to use (.2 thru .19). Save the change and reboot R1.



2. Disconnect R2 from R1, then access R2's config. Since you're going to change R2's LAN IP, I recommend turning off R2's LAN DHCP function first, then set R2's LAN IP to 192.168.1.2 and save that change. R2 will probably need to reboot.



3. Connect R2 to R1 via their LAN ports (don't use R2's WAN/Internet port). If you're still connected to R2 you should get an IP from R1. Bring up your browser and make sure you can access R1's config page and R2's config page. Make sure you can use the Internet.



4. If you plan to use Wi-Fi on both routers, make sure their channels differ by at least 5 channels (for example, If R1 uses channel-1, set R2 to channel-6). You can make the SSIDs the same or different -- it's up to you. Same with their Wi-Fi passcodes.
