Whats the difference in these network setups?

    (INTERNET)===MODEM===SWITCH===ROUTER===ROUTER



    OR



    (INTERNET)===MODEM===SWITCH===ROUTER(both conneted to

    switch)



    OR



    (INTERNET)===MODEM===ROUTER===ROUTER


    OR




    (INTERNET)===MODEM===ROUTER===SWITCH===ROUTER


    In network diagrams 1-4, which one will work more efficient for gaming,less packet delay,etc.?

    Does the different positions that the routers and switch take, affect the network performance?
    If it does what'll happen in diagram #2 where the switch connects both routers(seperately in each network port), does it create less delay in data getting in&out from the modem?

    Internet - Modem - Router1 - Router2

    Make sure DHCP is disabled on router2 and that you connect the 2 via LAN ports on both routers.

    Why should DHCP be disabled on router2 if it works fine for me?

    You should only have 1 DHCP server on your network. Otherwise you can run into issues with computers not being able to talk to each other. Also Router1 and Router2 have to have different IP addresses (ie. 192.168.1.1 and 192.168.1.2)

    Router1 also needs to be in Gateway mode, and router 2 in Routed mode. what is the physical length of the LAN?

    Both have different IP ranges 192.168.15.1 & 192.168.1.1



    i too need router two as gateway to connect to the internet

    Thanks toxic, but now it's really a problem this time.


    This is what im doing right now: I am configuring both routers to be on the same subnet as my DSL MODEM/ROUTER. I'm also using the modem's DHCP IP range192.168.1.1~192.168.1.253 to divide it into three groups of different IP ranges for each router to use.


    SUBNET MASK: 255.255.255.0
    Network IP = 192.168.1.0
    Broadcast IP= 192.168.1.255
    DSL modem IP(local)= 192.168.1.254
    Useable Host IP's= 192.168.1.1~192.168.1.253


    Here's what I've done so far:

    -Set Router#1 to use local IP address 192.168.100 & DHCP range is 192.168.1.1~192.168.1.50
    -Set Router#2 to use local IP address 192.168.1.200 & DHCP range is 192.168.1.120~192.168.1.170
    -DSL Modem/Router to have DHCP IP range 192.168.1.210~192.168.1.253

    *The reason why I set random IP addresses to be configured is for security purposes.

    (INTERNET)===MODEM===ROUTER#1===ROUTER#2

    The problem is that after configuring Router#1 to be on the same subnet as my Modem/Router it doesn't receive a GATEWAY address to connect to the internet(The modem's local IP address).

    Router#2 receives it's GATEWAY address, which is Router#1, but also cannot connect to the internet. Am I missing out on something in this network setup?

    NEVERMIND... i just needed to change my subnet mask to 255.255.255.192 in order for the IP ranges can be divided in three groups and the routers can now communicate with one another. FROM here on I've configured everything properly, so it looks like I don't need no more help.
