Hi all!

I'm a greenhorn admin of a 40-user dorm-network what consist of the following.
MODEM-SERVER-SWITCH-USERS

The network is getting slower, and I want to find out why. My first assumption was there is some config-problem with the server, so I want to bypass it to see if the network will be faster.

I have an Dlink DI 524 router. How can I use it to bypass the working server and connect to it.
So I want to get:
MODEM-SERVER-SWITCH-USERS
-ROUTER-SWITCH-ONLY_MY_TESTCOMPUTER

How do I have to configure my router? (static ip or...)

Best regards
therifulio

what is this server that you speak of, what does it do?

for testing purposes you can do this

modem -> router -> test PC
or even modem -> test PC

your router config will depend on the modem config, i can't say based on the info you have provided

Thank you for your answer, and thank you for pointed out the inaccuracy of my question.
(Sorry for being late: I just had returned from a trip.)

The server provide internal IPs via DHCP for all hosts on the network.

Since my post I have found the solution:

I set up a router right after ISP's modem with DHCP and with LAN IP 192.168.99.1. I connected it directly to the switch. When I want bypass the server with DHCP to find out if it's the bottleneck of the network I just set my computer to static IP for instance 192.168.99.5, so I connect to my router. With static IP I assume I can avoid the collision of DHCP servers (or something like that).

ISP --- SERVER with DHCP ----------- SWITCH --- MYCOMPUTER
--- ROUTER without DHCP ------ SWITCH --- MYCOMPUTER (with fixed IP)
