For watever reason the D-link router refuse to assign an ip to my ibook. When I use Airport Express card to access the router, the router recognize it and assign an ip to the iBook. But when I try to connect from the router to my iBook using ethernet cable, the router refuse to recognize it. The iBook just says that the ethernet cable is connected, but no ip is being assigned by the router, therefore migh not be able to connect to Internet. Im using D-Link router DI-724P+ and Aztech High Speed Modem. Anyone please help me, I want my iBook to connect to the router using ethernet cable.

Check the settings on your iBook. You usually have to set up your client machine (the iBook) to accept assigned IPs via DHCP for each connection type you have ... meaning you may have it set correctly already for your wireless but will have to set it up for a ethernet connection as well. Lemme know if you can't get it figured out quickly and I'll show your what exactly what you need to check.

I have check several time already, but the router still refuse to assign a private address to the iBook. The iBook just assign an ip to itself which is incorrect. The built-in-ethernet status says that "Built-in-Ethernet is currently active. Built-in Ethernet has a self-assigned IP address and may not be able to connect to the Internet". I have the config on my router many times, no problem at all. But when I connect the iBook to the router, it just refuse to recognize the MAC address on my iBook ethernet card.

So, you are saying when you go into System Preferences -> Network and highlight "Ethernet" on the list of connections and then hit "Configure" it looks like this ? You must set your ethernet port of your connection to accept DHCP and hit 'Apply Now' at the bottom or it will not be properly set. Also, on the PPPoE tab, you must have connect using PPPoE turned off for Ethernet.

Krusty · Oct 14, 2004, 07:59 PM

Ahh .. I see you changed your post. Yes the "self assigned IP" thing is a sign that you need to change your ethernet to passively accept DHCP from the router.

tysoh85 · Oct 14, 2004, 08:01 PM

Yeah that is exactly wat I want to see for my configuration, but it did not assign any private address to my iBook. Instead the iBook assign an ip :169.254.120.185 to itself, which is wrong. And it does not display my router ip address. It does not find my router. I really hava no idea wats wrong.

What do you mean change your ethernet to passively accept DHCP from the router?

Krusty · Oct 14, 2004, 08:05 PM

did you hit "renew DHCP lease" ?

tysoh85 · Oct 14, 2004, 08:06 PM

Yes, I hit many many times. But no respond

When you connect to the internet via a router, you must TURN OFF any manual connection info on your iBook. All of the settings necessary to connect live in the router now and the router supplies the info to the iBook. Check these things:
On the PPPoE tab, turn OFF connect via PPPoE
On the tab in the screenshot, set the Dropdown to "Using DHCP" (as in the picture)
Hit "Apply Now" at the bottom
Hit "Renew DHCP lease" if necessary.

Also, to reply to post's directly (like I am doing with yours), just hit the little 'Reply' button directly above the post and it will quote my text in you response (so you don't have to cut and paste)

I have done what you mentioned above, still no help also... Will the problem lies with my router? But if the router could assign ip to my PC using ethernet port 1 and also wirelessly over to my airport express card, then wat could the problem be? Is my iBook corrupted?

Problem may be in your router .. but I couldn't help you with that since I don't have that router in front of me. However, the fact that you are able to connect via airport would imply that your router is probably set up fine.

Here's the next best advice I can give you. Hit the 'Assist Me" button beside the "Apply now" and it will walk you through setting up a new connection. Name the connection "Landline" or something so you know that it if for ethernet instead of wireless.

I have tried as well, but it keep prompting me to connect using a static ip address. It says" You cannot connect to your Ethernet network automatically, so you need to enter information to set up your connection. If you ..."

Krusty · Oct 14, 2004, 08:26 PM

Ahhh .. on you "location", did you select "Network Port Configurations" from the dropdown. This will list all available ports (wireless, ethernet, modem). Is "Ethernet" at the top of the list ? If not, it may still be connecting via wireless instead of via ethernet

Oh yeah, its not at the top list, but I have moved it up already, still the same...

tysoh85 · Oct 14, 2004, 08:33 PM

Im doing a disk utility scan now. . . This is the first time the iBook is giving me problem...

hmmmm ... it may be in your router. did you set up the router yourself of did the service provider set it up for you ?

I set myself.

Did you do anything like MAC address filtering ? Your ethernet MAC address WILL be different from your Wireless MAC address. The only time I've experienced a problem like yours is when I had 2 separate routers on the same network.

Can you ping the router from the iBook when it is plugged in via ethernet ??

[edit]
Oh hey, I just remembered something. Can you change "Using DHCP" to "Using DHCP with manual address" ? -- then manually pick an IP for the iBook. If you can connect this way, then its probably a problem with your router/network setup.

Yeah, I do MAC address filtering, but I did not filter off the ethernet card on the iBook. Nope, I cannot ping the router.

On many D-Link routers there is an option to set the router to Short Preamble or Long Preamble. Short Preamble is the default but Apple Airport cards require Long Preamble. Try changing Short Preamble to Long Preamble. The setting will be in your D-Link setup utility. Go to the Advanced Tab, then click on the Performance button on the left side.

I did not see any preamble settings

aaanorton · Oct 14, 2004, 09:12 PM

Are you using the same ethernet cable that your PC was using? Maybe the cable is bad. Use a known working cable. Have you tried all the ports on the router?
MAC address filtering does not affect direct wired connections, only wireless. So you need not worry about that for an ethernet connection.

What model D-Link is it?

Surprisingly, on my D-Link DL614+, MAC address filtering affects both wired and wireless connections. (On my old SMC, it affected only wireless.)

I had that Problem until I assigned a DHCP Client ID, for example I used number 4, somehow this maked things work

warren121 · Jun 3, 2005, 09:52 PM

go to ibook ->library -> system configuration -> preferences and put "com.apple.airport.preferences.plist" file in the trash. Then restart the computer. Just curious to see what happens. I have the same problem with the bogus ip through DHCP.

CABLES, CABLES, CABLES!!! tysoh85, have you done anything about the cables you're using? At this point you MUST use a KNOWN GOOD cable between your Mac and your router. You seem to have gotten into the "flat spin death spiral" of messing with settings, and it's getting you nowhere fast. Use a cable that you CAN PROVE IS GOOD (by seeing that it works for another computer and that router) between the Mac and the router, and restore everything to its default setting: "Obtain IP through DHCP" on your built-in ethernet port.

Also, use a router port that you know is working correctly. My first move would be to unplug the cable from your (working) PC and plug it directly into the Mac.

You ARE plugging the Mac into a LAN port, right? Not the WAN port...

John Strung · Jun 4, 2005, 09:35 AM

Try temporarily turning off MAC address filtering in the router.

MAC address filtering in DLink routers applies to both wired and wireless connections. If you have MAC addresss filtering turned on, you must also add the MAC address of your ethernet card.
