My client has a Apple Mac Book and dont have connection

If initially the Win XP laptop was connected to internet at the cable/dsl modem, its MAC address would have been registered on service setup. If the router is now in place between the Win XP laptop and the cable/dsl modem, you would need to go on the Win XP laptop and log into the router as admin to clone the Win XP laptop's MAC address to the dlink router's WAN interface (internet facing side) so that the cable/dsl modem will see the previously registered MAC address and will enable the internet access.

That's not your Macbook but your internet provider.

Try rebooting your network, which would involve powering off, powering on your cable or DSL modem, and your router. This should refresh your networked devices with a new set of IP addresses. Usually, when you can't connect to your wireless network, it's due to an IP address conflict.

You'll need to set up the internet connection. Connect your modem, and open 'Network Utility' (/Applications/Utilities/Network Utility). Follow through the steps and you should be able to connect fine.
If not, the people at the Apple Store are always very helpful. Explain what type of modem you have and they'll be able to give advice.
Does the modem/internet connection work with other computers, out of interest?
Hope that helped!

Yes, you just need to connect the Airport to the modem. That way, the Airport will fetch the internet connection and distribute it to all your WiFi enabled device. You don't need any other hardware. You just need to configure the airport using your Mac computer.
Here's a quick setup guide from Apple.com:

I believe you have an IP Address conflict or the router needs to be configured for PPPoE. Here's how:

Basic DSL Setup - PPPoE


Most Internet Service Providers offer PPPoE authentication. Please consult your ISP if you are not sure if PPPoE could be used.

To configure your router for PPPoE you will need to set your router's WAN (INTERNET) port to 'PPPoE' option. However majority of Modems nowadays already have PPPoE enabled. If your modem has PPPoE client built-in, you need to select the 'DHCP' option in your router. The router is set to this option by default.

Configuration steps:

Step 1
Connect the broadband modem to the WAN (INTERNET) port of your router. If the modem has USB connection make sure that it is NOT connected to any computers via the USB cable and that the modem is switched to Ethernet (not USB). Only the modem's Ethernet port should be connected to the router's WAN (INTERNET) port.
Connect your computer(s) to the router's LAN port(s) or establish connection to it wirelessly.

Step 2
Open your Internet Explorer and log into your router by typing in its IP address (in most cases the default IP is http://192.168.0.1 ). Note that you do not have to be on the Internet in order to access this address because you are just connecting to your router's address. Specify username and password for your router, the default is `admin' (optional) and password is blank (nothing).

Step 3
After logging into the router select Setup. Set Internet Connection to 'PPPoE' option.
This can be done by either clicking on Internet Connection Setup Wizard or if you want to set it up manually, then click on 'Manual Internet Connection Setup'. Note that it is very common for broadband modems to carry out the PPPoE authentication for you. In this case you need to select the 'Dynamic IP' option (DHCP) in your router, do not select PPPoE. If you have such modem proceed to Step 5

Step 4
If your broadband modem does not have PPPoE function, select the 'PPPoE' option in the router and enter your account details (username and password given by your ISP). Note that some ISP's require username to be as your full e-mail address (ex: [email protected]).

Step 5
Click on SAVE SETTINGS and then on REBOOT THE DEVICE to apply the new configuration. Recycle power to modem.

You do not have to run any login client (like PPPoE) on your computer in order to connect to the Internet. If you had it setup when using the modem without the router, disable it in Internet Explorer under Tools > Internet Options > Connections > set to 'Never dial a connection'.

If you did not have to run PPPoE login client on your computer when modem was directly connected to your PC, your ADSL modem has PPPoE built-in. In this case set the router's WAN (INTERNET) port should be set to the 'Dynamic IP' option.

If your ISP requires PPPoA connection you need to make sure that your ADSL modem supports PPPoA (PPPoA can not be used on Routers which do not have ADSL Modem built-in). If your modem will be carrying out PPPoA connection you need to set your router's WAN (INTERNET) port to the 'DHCP' option.


If you are having difficulties accessing the Internet:

- Turn the modem and the router off for a minute and then turn the modem first and then the router.

- Log into the router and go to Status page. Note what IP address it is getting on the WAN (INTERNET) interface. If the IP address you see under WAN (INTERNET) appears to be in the same range you are using on your network (e.g. 192.168.0.x), you will need to change the range you are using on your LAN to something different, e.g. 192.168.88.x. You can do this on your router under Setup > LAN Setup. Note that after changing the IP of your router you will only be able to access it through its new IP, e.g. 192.168.88.1.

- Select the MAC Cloning option. Click on Clone MAC Address button. Do this from the computer which the broadband modem was directly connected to the last time. This will place the MAC address of your computer into the router. Save settings and reboot the router. Reboot your broadband modem as well.

- Uninstall your antivirus software (sometimes disabling or closing the software is not enough) and reboot your PC.

Router's have their usual way for them to work with your preferred Cable / DSL Internet Service Provider.

Cable Internet usually requires a MAC clone and power cycle to work properly while DSL Internet often required a username and password that came with your DSL povider.

If you want to configure your D-Link router then try accessing it Web Interface;

This instruction is for Cable modem installation however if you're using DSL modem then just change the WAN connection type to PPPoE and type your user name and password.

Step 1 Log into the web-based configuration by typing in the IP address of the router (default:192.168.0.1) in your web browser. The username is admin (all lowercase) and the password is blank (nothing).

Step 2 Click the Home tab and click the WAN button. Dynamic IP Address is the default value, however, if Dynamic IP Address is not selected as the WAN type, select Dynamic IP Address by clicking on the radio button. Click Clone Mac Address. Click on Apply and then Continue to save the changes.

Step 3 Power cycle the cable modem and router:

• Turn the cable modem off (first)
• Turn the router off
• Leave them off for 2 minutes**
• Turn the cable modem on (first)
• Wait until you get a solid cable light on the cable modem
• Turn the router on
• Wait 30 seconds

Step 4 Follow step 1 and log back into the web configuration. Click the Status tab and click the Device Info button. If you do not have a public IP address under the WAN heading, click on DHCP Renew and then click Continue. It may take a few minutes to obtain an IP address.

Hope this helps!

If you can detect wireless connections in your area, then you have a wireless card in your Apple.
You cannot connect to the Internet unless you have a DSL or cable modem that connects to an Internet Service Provider.
You can connect to the Internet using a public access WiFi hot spot, these are located at McDonalds, Star Bucks and at the airport etc. and some Internet Cafe. There maybe some charges for these Internet connection.

The local Apple Genius Bench was nice to reload iChat and OS for us. But he could not get iChat going for me and my relative. It looks like iChat will have trouble between DSL and Cable but DSL to DSL and Cable to Cable each case is fine. Anyway, after connecting to Apple iChat Test Site
Appleu3test04, my MacBook started to work better with iChat as my relative is able to see and hear us although on my end the incoming picture is not too clear. Then finally Upgrade of New OS seems to make the picture sharper. Thinking back, the original problem came from Modem upgrade to higher speed but I did not use the new DSL telephone filters. Please post this up to help other frustrated iChat users. Anyway, we still like Apple! By Jim on 05/30/2009
