Title: DIR-100 - Same IP address on computers
Post by: Hampe on January 09, 2014, 05:57:48 AM

Hi!

I did not find the specific forum board for "DIR-100", so I post here.

I have, as the topic says, a D-Link DIR-100 switch connected after my broadband modem. I have 3 computers connected to the D-Link and all can access to internet. BUT, all computers have the same IP address, and they shouldn't.

My question is: how do I make the switch to give each of the computers it's own unique IP address? I've called my ISP and they don't know how to do that with a switch, just via the modem..

UPDATE
I have:
Hardware Version: D1
Firmware Version: v4.01

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modem Mfr. and model # do you have?
• What ISP Modem service link speeds UP and Down do you have?

Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.

• Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
• Ensure devices are set to auto obtain an IP address.Do not use Static IP addresses that are set on the devices.

Thank you for the reply.

ISP Service: ADSL
ISP Modem: Zyxel 2601
ISP Speed: 21 Mbit's

I've tried to reserve IP addresses but then the internetconnection died. When I removes the values, the internet came back again. I dont know what to do anymore.

It would be very good if you can help me with this annoying problem.

• If this ISP modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) and How NAT Works (http://cognitiveanomalies.com/cisco-nat-how-nat-works/). To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.

Okey. I looked at the Device Info, and I don't have a 192.168.0.# address. I have a 85.224......

So the modem router is bridged. Should I call my ISP one more time and see if they can guide me, or do you guys have any answers?

Thanks!
