I would set the new wireless router to have a static ip address on the same subnet as the first router.  Then set the DNS and Default Gateway the same as the first router.  When computers connect they should pick up an ip from the first router.

The Network Key you're probably asking for is on a sticker located, underneath the router. Can you check?

Here's a way to configure your router for your existing network (assuming you already have one) :

If you have an existing network, chances are you have already configured network services on the network. In this case, you would use the router as a pure Access Point to extend the range of your network by allowing more attachment of wireless and wired computers. You MUST also turn off the DHCP server on the router if there is a DHCP server running to avoid IP address conflict.

To configure the router as an Access Point with the DHCP server disabled:

  1. Open your web browser and go to http://my.router, (or the default address

  2. Click the Basic Settings tab on the top navigation bar.

  3. Select Access Point Mode.

  4. Click the Next button.

  5. Click OK to dismiss the DHCP disabled message box (The DHCP server will be disabled in Access Point Mode by default).

  6. Click the Advanced Settings tab on the top navigation bar.

  7. Click the Advanced IP Settings tab on the left navigation bar.

  8. Assign an IP address to the Wireless Broadband Router.

    note.gif NOTE: The IP address should be reserved by the DHCP server. The Wireless Broadband Router cannot act as a DHCP client, therefore, it needs a static IP address for its LAN interface.

  9. Click the Submit button.

  10. Click the Save & Restart button.

  11. Note the status bar at the bottom of the screen.

  12. While the Wireless Broadband Router resets, the Power light on the front of the unit blinks.

  13. When your web browser returns to the main page of the Wireless Broadband Route, the device has successfully restarted with the new settings.
    note.gif NOTE: The main page may not return if you have changed IP address of the router in Step 8. To view the main page, type the new IP address of the router in the web browser to access it.

  14. Plug an Ethernet cable from the existing local network into any LAN port on the Wireless Broadband Router.

Wrt54g2 dhcp problem

You must enable the DHCP setting on wireless router if you've configured the computer's wireless adapter to obtain an IP address automatically. If not you will get the "failed to acquire an IP address" error when you try to connect to wireless network! Also don't forget to configure big enough IP range on router's DHCP setting, because the router won't be able to assign IP to 6 computers if you only configured 5 IP space on router.

To check your Linksys wireless router settings, open IE browser and type in the Linksys configuration IP address
and login = admin and the PW = admin (if you didn't change the default password) - The default password should be changes to stop unauthorized access into the Linksys router.
If you cannot get into the Linksys router configuration wirelessly, then you need to connect a LAN cable from the computer to the Linksys router.
Check the DHCP and wireless settings. Take a note of the wireless settings (ie SSID, encryption etc.) and check the wireless card setting in the computer, it needs to have these settings for the wireless/LAN to connect to the Linksys router. The TCP/IP settings on the LAN?wireless cards needs to have Obtain IP address automatically and Obtain DNS server address automatically.
Let me know if you need further assistance.

Need to change IP address for this or my Actiontec router

Take each thing seperately, in other words connect them directly to your computer first. Normally only 1 thing on a network should be a DHCP Server. But often a router will have a WAN port and and another router will be plugged into that. In that case the "another router" can run DHCP and will assign that to 1st router. 1st router now knows how to get to "another router" (2nd router). Which should allow you to get to it from 2nd router.

You can't talk to another /24 network if your computer is not on that /24 (aka Class C - The 1st three octets have to match. Unless ... there is a router inbetween your computer and "another /24 network" - that is on both /24 networks. In that latter case that router inbetween has the route to the "another /24 network" and can get you there.

To configure router gear where DHCP isn't working plug directly into it on ethernet switch or LAN port. Knowing it's IP Address you have to manually configure your computer (take it off of Automatically) to match the 1st three Octets (1st three of the dotted decimal numbers) and with a 4th octet in the range 1-254, because .255 is the broadcast address. Make sure you pick a 4th octet that is not in use to your best knowledge. Not the ip of the router, or anything else that you are aware of on the network range. I usually pick .10 because normally nothing is on the lower end of a dhcp range.

Anyway hooked up directly and manually IP address set, you should be able to go about changing IP Address of a router or access point. Keep in mind if you change it outside of the /24 subnet you and it WERE IN that you will lose access to it again. And will have to change your manually configured IP Address again. Or go back to automatic - if you have now also enable DHCP on that router device.

Note that for an access point (range extender?) it doesn't usually matter that it is on a seperate /24 network ... as it doesn't operate at Layer 3 (Network, IP Addresses and such) anyway. It just switches Ethernet / Wireless Ethernet frames anyway - all of the IP stuff just transparently passes through it. You probably get DHCP from your 1.1 router ... and talk the local network and Internet just fine. You could use the above MANUAL IP method whenever you want to look in the wireless access point. But unless it's broken / not working, you shouldn't have to. Access Points normally don't do any routing at the IP level and don't run DHCP - so all of that simply doesn't matter. Of course you might like it on the same network range (/24) as your other router for ease of maintenance. Just don't plug into a WAN port, plug into a Switch/LAN port on your main router. -

You may want to enable the DHCP reservation feature of the router.
What is DHCP Reservation and how do I configure it?

What is DHCP Reservation?
A DHCP reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client.
You can configure a DHCP reservation in your DHCP server when you need to reserve a permanent IP address assignment. Use reservations for the DHCP enabled devices like print and file servers or other application servers which always have the fixed IP address on network.

Step 1: Access the router's web-based setup page. For instructions, click here
Step 2: When the router's web-based setup page appears, click Setup.
Step 3: Click on Basic Setup.
Step 4: Make sure that DHCP Server is Enabled. Then, click the DHCP Reservation button if you want to assign a fixed local IP address to a MAC address.

Motorola SBG900 Assign network address to computer

I guess your modem router was already configured well since it worked already previously. It seems that your motorola router is set to broadcast dynamic IPs (DHCP enabled) and your last connected Pc and laptop were configured with static IP. Please check your "network connection" setting and make sure it is set to "Obtain IP automatically"
