Snow Leopard internet connection issue via Ethernet

[acevergreen]

I currently have MacBook 13" and iMac both running on Snow Leopard. I have no problem connecting to the internet via Airport Express wifi but if I have to connect directly to internet from Ethernet port using Ethernet connection I can't connect to it. The Internet and Server lights are showing "amber" in the network diagnostic tool.

The modem is the DLink DSL 302G. I have used http://10.1.1.1/ to ensure the username and password of the ISP are correct.

What I don't get is if it works via Apple's Airport Express router why wouldn't it work with straight Ethernet connection from the modem?

Is it something really simple that I am not doing correctly?

Thanks in advance.

Not too familiar with Airport Extreme, but do you have the ethernet cable running from your modem going into the WAN port on Airport?

Link to the airport page so you know which one is the WAN port... Sorry if you have this done already, I thought maybe you hadn't from the way you had worded your post

The ethernet port on an Express is just for input, not output. It is there for if you had only and wired network that you add the express via ethernet and distribute IPs via wireless. If you wanted the wireless router to distribute IPs via the ethernet then you should have got an airport Extreme (or some other third part wireless router).

Plus if you wanted to use the Airport Extreme directly to the ISP modem did you reset the modem first 9waiting at least three minutes before turning it back on)?

May be I didn't explain clearly.

Connection1 - Dlink modem is connected to Airport Express router and it provides wifi network.

Connection2 - Remove Airport Express Router from the DLink modem and connect the laptop (MacBook) directly to the DLink modem using Ethernet cable.


Connection1 works for me without problems. But Connection2 does not.

When you swap-out devices that are connected directly to the modem, you must reset the modem.

Yes I did that. Still didn't work.
