No IP address via LAN (+)

Milan have you got the user manual as it clearly explains how to set up the router and configure it manually !

Your modem device already on your network has to have an IP address of 192.168.0.1 and according to the user manual the router detects the conflict in ip address and allocates its IP address as 192.168.1.1. If you IP address is different say 10.0.0.1 then you will have to plug just the router in to your Laptop and alter the i/IP address to 10.0.0.2 and turn off the DHCP server if the modem or existing router has DHCP. You will need to alter any existing DHCP server to have the first 10 IP addresses skipped for available leases to the computers.

How did you connect the computer to the router. If you are using a DSL modem it will have a DHCP server in it that is allocating IP addresses across your network. If you added the router to the computer via a hub or network switch what is the computers ip .
address. Remove the WI FI router - turn off P.C and then Go to cmd or dos prompt if windows based system and type in ipconfig and press enter to see if ip addresses are 10.0.0.2 if they are your dlink router uses 192.168.0.1 so you need to make the dlink router ip addressand subnet setting to match the Modem ip addresses of the DHCP server. Change the ip address of the dlink router to be 10.0.0.2 and change the modem to allocate DHCP IP addresses from 10.0.0.10 to 10.0.0.255. Only do this if IP addresses are 10,0,0,1 to 10.0.0.,254 on the desktop p.c with the dsl or cable modem connected.without the router being involved. (you may need to ask the ISP what the user name and password is of the modem and it should be ip address xx.xx.xx.1 so type this into a browser to change the modem settings. 10.0.0.1 or 192.168.0.1 just remember if the modem is 192.168.0.1 so is the Wi router from d-link and you will have an ip clash problem)
. How do you do this by ethernet connection from only the desktop directly with only the Wi FI . router. Go to a internet browser and type in the URL 192.168.0.1 and then change the router ip address to match what the DSL modem DHCP issues..
Page 14 of Router instructions see http://files.dlink.com.au/Products/DIR-615/Manuals/DIR-615_C2_Manual_v3.10.pdf
in the manual it states to use a direct ethernet connection for the setup program but you need to be connected to the internet for it to work but if the IP addresses are wrong or clashing will have no internet. You also want to set the modem as the DCHP server and disable the DHCP server in the set up of the wi fi tand set the WI FI router default gateway as the ip address of the Modem. if any DHCP server options in the WI FI router sert to the modem ip address. .

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.

Plug the printer to a DHCP capable LAN. Give it a moment to connect. While the printer is on, hold down both, the feed and X buttons on top of the printer. It will print out a configuration page with the DHCP address. Type that address in a web browser. Click the network tab. Select manual address; then type the address you want. Then click save. DONE

Yes, it must be attached to the network 0. Install the yellow machine software on the PC 1.Log on to the Yellow Machine Manager. Go to “Logging On To Yellow Machine Manager” on page 8. 2.From the Yellow Machine Manager, click Network > Network Interfaces. The Network Interfaces window appears. 3.Click Edit. 4.Select Yes to Enable LAN Interface. Default: Yes (Enabled) • If you select No, all other LAN option fields are blocked. • If you disable the LAN Interface, the only access to the Yellow Machine appliance is through the WAN port. Anthology Solutions does not recommend this configuration. 5.Check Enable DHCP Service if the DHCP service is needed for the PCs attached to the Yellow Machine appliance’s LAN ports. This setting makes the Yellow Machine appliance the DHCP server for your LAN (or sub-network), providing IP addresses dynamically for the clients connected to the LAN ports. Default: Checked (Disabled) 6.Select either Obtain IP Address Automatically from DHCP Server, or Static IP Address. Default: Static IP Address • Choose Obtain IP Address Automatically from DHCP Server if your Yellow Machine appliance connects to either a router that has DHCP service enabled or to a cable modem. This setting makes the Yellow Machine appliance a DHCP client on your network. • Obtain IP Address from ADSL provider is greyed out. • Choose Static IP Address if your network is locally defined and controlled and does not use DHCP services. Type the IP address manually. 7.Specify IP address and Subnet mask if you selected a Static IP Address, and click Apply. 8.Click Yes to confirm, No to abort. The changes takes affect within five seconds after the network interface change notice appears.

The LAN should not ever log off but either you are talking about the Internet, which can, microwave devices (ovens, wireless phones) that intermittently interfere or dynamic ip addressing cycles that assign you the 169.xxx.xx.x from within Windows attention deficit disorder manager. You can assure static assignments of ip addresses for your LAN (write down the ip address and default gateway when you are logged on to see what they should be) or log on to your router (Start>Run> type http://192.168.1.1 for Linksys, user name linksys, password is admin and you can configure your LAN and WAN. Select DHCP for cable modems, PPPoE for DSL or STATIC for ensuring LAN ip address assignments. ~Steve

that is right the access point does not have a dhcp server. that will give an ip address to all of your computers or device connected to it wireless. If you have a modem with a dhcp server there will be no problem with the IP but if the modem does not you must have a router and now an access point.

Connect a computer to linksys lan port 1-4, point browser to linksys http://192.168.1.1 under Setup->Basic Setup->Internet Settings choose "Static IP" and fill in the fields below... the field for gateway should be set to the static ip of your cable modem. the field for netmask should probably be 255.255.255.0. It may help to turn on DHCP for local network so that lan hosts can get their ip's from the linksys.

The D-Link DFE-916 hub is unmanaged, there is no web management console. You will need setup your broadband modem setup as DHCP to assign your workstations IP address, (or you could go static IP, but DHCP is suitable for most situations)
Topology should be like this:
MODEM-----Hub/Switch-------Computer.

here the link the manual,

concerning the bandwidth pirate, you will need the offending computers mac address, (Media access Control)
to do this:

click start,
Run,
type in: ipconfig /all
the line that reads: "Physical Address" is the MAC address
the format will read like this: xx-xx-xx-xx-xx
Now check your broadband modem or you routers management console for a MAC filter, this is where you can allow or ban a device or computer from the network.

Good Luck!

you might have configured your lan settings wrongly.

If your modem was setup for DHCP then you configure your lan to receive IP address automatically, DNS automatically.

If DHCP is disabled on the modem, you have to USE static IP Address for your lan ip and default gateway should be your modem default ip.

the default IP for modem is usually 192.168.1.1
if DHCP is disabled on the modem the sys ip is 192.168.1.3

So Configure your LAN setting as follow and Type http://192.168.1.1 in the address url.

Lan Settings:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1

click ok.
and type the above url, press enter the modem will ask you for username and password.

Good Luck.
