3CRWER100-75 no DHCP IP on child routers

When I connect two 3CRWER100-75 routers on for "base" and the other for "repeater" I configure both routers like:

Router #1:
The router "base" configured with WDS on and the option WDS-RootAP (Base router) DHCP enabled.

Router #2:
The router "repeater" configured with WDS on and the option EDS-STA (Repeater) DHCP disabled.

When I connect thru 4-port, the PC's does not connect, no DHCP IP assigned on the child router.

On the WLan pc's no iP assigned from dhcp server of the base router

    We have an OfficeConnect Wireless 11g Cable/DSL router, and we want to configure it as a wifi repeater. The modem-router which receives the DSL phone cable is a D-Link model. I configured the 3Com enabling the WDS and specifying the D-Link's MAC Address to allow repeating its signal. I also set a different IP for each router. I'm using two different SSID for each one, but the same WAP key for both.
    Our laptops connect to the 3Com but don't receive Internet access.
    What I'm doing wrong?
    The 3com product user guide says few things about it...

    Thanks in advance,

How to configure router & switch


You shouldn't have to configure anything except the PC's should have IP and gateway set to auto.

Here is how it works:

A router connects two separate networks and manage the traffic between them.

In most home network applications the router connects your local group of computers and devices known as the LAN with the Internet, commonly called the WAN or Wide Area Network.

The router usually assigns unique Local IP addresses to all of the devices connected to it via a service known as DHCP. The addresses assigned by your router are private addresses http://en.wikipedia.org/wiki/Private_net... and are not routable across the Internet.

Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks. Computers that are connected to IP networks must be configured before they can communicate with other computers on the network. DHCP allows a computer to be configured automatically, eliminating the need for intervention by a network administrator. It also provides a central database for keeping track of computers that have been connected to the network. This prevents two computers from accidentally being configured with the same IP address. http://en.wikipedia.org/wiki/Dynamic_Hos...

Your cable or DSL modem will get a Public WAN IP address from your ISP's DHCP service. These public IP addresses are leased in blocks by your ISP and are Internet routeble. The modem is connected to the WAN port on your router. The router will manage the traffic between the devices on the LAN and the Internet.

If your 5 port switch is connected to one of the router's LAN ports and router's DHCP is on then it will configure the clients attached to It automatically.

How to configure a Router?


How to determine the WAN configuration or Interntet configuration of a SOHO Router?
1. Connect the computer to the Modem via Ethernet cable. Make sure you are able to going online 2. After confirming you are online. Go to Start->Run. Type "cmd" on the Run window. 3. Type "ipconfig" on the command prompt or Black window or DOS window 4. You will be getting IP address,Subnet Mask and Default Gateway
There are 4 possibilities of IP address you can get
i)Public IP address under PPP adapter. -Router has to be configured in PPPoE mode to get a WAN IP. This will require a Username and Password from ISP ii) Public IP address under PPP adapter and Private IP address under Ethernet adapter -Router has to be configured in PPPoE mode to get a WAN IP. This will require a Username and Password from ISP iii)Public IP address under Ethernet adapter -Router has to be configured in Dynamic IP or DHCP mode to get a WAN IP -If it is still not getting a WAN IP address. * Click Mac clone on the router's WAN configuration * Power-cycle modem and Router. iv)Just a Private IP address under Ethernet adapter -Router has to be configured in Dynamic IP or DHCP mode to get a WAN IP -If it is still not getting a WAN IP address. * Power-cycle Modem and router.
After determining the WAN mode, it is time to configure the Router
1. Connect the Modem to the WAN port of the router. Connect the computer to the LAN port 2. Go to Start->Run. Type "cmd" on the Run window. 3. Type "ipconfig" on the command prompt or Black window or DOS window 4. You will be getting IP address,Subnet Mask and Default Gateway. The Default Gateway will the IP address of your router 5. Open a Web browser and type http://192.168.1.1(where this is the default IP of the router. This will be different from each manufacturer) on the address bar. 6. Go to WAN settings or Internet settings and select the options based on the above mentioned possibilities

Configuring a 3COM 3CRWDR200A-75 router as a repeater


SETTING A ROUTER AS A REPEATER 1. Connect your computer to the repeater router's RJ45 port with a LAN cable. 2. Open a browser, then enter the router's URL configuration's IP address, This is usually something similar to 192.168.0.1 3. Enter the configuration user name and password. The router will display the various router settings. 4. Go to the page that changes the IP address of the router. Changed the IP address so that it is not the same as the main router on the network, or any other network devices. If the main router on the network is set to 192.168.1.1 then the repeater router should use a higher number (ie. 10), such as 192.168.1.10 or higher, depending on how many devices are on your network. 5. Disable the repeater router's DHCP server. This setting should be on the same page as the IP address, (this may be different depending on the make of the router). When the main router is operating normally, this server assigns an IP address to every device that is connected to your network. Because this router is used as a repeater, the main router on your network will still issue the IP addresses. 6. Also turn off the DNS server, if it is activated. This function will be taken over by the main router. 7. Disable any firewall settings on the repeater router. This is usually in the "Security" section, depending on the make and model of your router. 8. Remove all in the "Port Forwarding" section. Some routers may refer to this as "Applications and Gaming," and it allows less-restricted access to the internet. 9. Set the operating mode switch to "Gateway" or "Switch" if applicable. Also, if the repeater router is a wireless router then disable the wireless access or set it to access point only. 10. Save the settings for each page, and reboot the router. When the router boots up, the changes will allow it to act as a simple repeater. 11. Now, place the repeater router in a new location and connect both routers with a Ethernet cable in each of the router's RJ45 LAN ports, and power it up both routers.

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.

Dhcp setup on a Cisco 2851 router


Let's look at how to configure basic DHCP on an IOS-based router. For this example, we'll start off with the default configuration on a Cisco 2611 router running IOS 12.2. (The configuration should be the same—or very similar—on all IOS-based routers).
To begin, connect the router's Ethernet port to a switch, and connect the switch to a laptop, which will serve as the DHCP client.
To configure Cisco IOS DHCP, follow these steps, which include sample commands:
1.Configure an IP address on the router's Ethernet port, and bring up the interface. (On an existing router, you would have already done this.)
Router(config)# interface ethernet0/0
Router(config-if)#ip address 1.1.1.1 255.0.0.0
Router(config-if)# no shutdown2.Create a DHCP IP address pool for the IP addresses you want to use.
Router(config)# ip dhcp pool mypool3.Specify the network and subnet for the addresses you want to use from the pool.
Router(dhcp-config)# network 1.1.1.0 /8 4.Specify the DNS domain name for the clients.
Router(dhcp-config)#domain-name mydomain.com5.Specify the primary and secondary DNS servers.
Router(dhcp-config)#dns-server 1.1.1.10 1.1.1.116.Specify the default router (i.e., default gateway).
Router(dhcp-config)#default-router 1.1.1.17.Specify the lease duration for the addresses you're using from the pool.
Router(dhcp-config)#lease 78.Exit Pool Configuration Mode.
Router(dhcp-config)#exit

I hope this is helpfull for you.

Thanks

How to set my wrt300n router to use static ip,... i´ve have a problem whit my ps3, and want to use static ip, instead of dhcp(dynamic) should i do it before i do it on my pc and how to do it on the...


Hi,
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.

RE: My posted. Connecting DSL/Router to DIR-628 internet router


Installing a router to work as the second one on a home networkrequires special configuration. Do the following on the second routerto ensure it (and the devices attached) function properly:1. Connect as local device or bridge - If connecting the second router via Ethernet cable, plug it into one of the LAN ports on the first router. If connecting the second router wirelessly, ensure the second router is set for client mode.Note that some home wireless routers do not support client mode; thesemust be connected by cable. Check your router documentation for detailson its client mode configuration support.

2. Check / change IP address - Most home network routers use a default IP addresssetting. Often, these default IP addresses will not work in a tworouter environment. Check the second router's IP address value andreset it if necessary to work within the valid address range of thefirst router (and to not conflict with any other device on the network).

3. Disable DHCP- To avoid IP address conflicts between all of the devices on the homenetwork, only one of your two routers should assign addresses via DHCP. All mainstream routers provide an option to disable DHCP as part of the router's configuration screens.

(My netgear router supports client mode. The 2wire supports bridged and router mode. My 2wire is the main router. I set up my netgear using my laptop. Once you change the address on the router.. You will only be able to directly access through the main router to the 2701.)

Configure your 2701 IP address to a static address in the 192.168.2.1 range and diable DHCP. Only 1 router can run the DHCP service. To disable Dhcp on the 2701.... log on to 2701> click on home network>advanced settings>uncheck enable DHCP>Next section is Public routed subinterface...Check enable and Aout Firewall Open>Input your main router address and mask>save config..

This worked with the Netgear router.. May not with your router. Good Luck! Hope this helps!
