Express/Extreme: Losing Internet?

[Jedi5]

Can someone please explain what I'm doing wrong here?

Extreme located in the basement office.
Express located in the 2nd floor to help extend/strengthen wifi signal.
Using utility, I have Express set up to extend wireless network.

When I connect (ethernet cable) my express to the router, I lose all my internet/network.

What am I doing wrong?
Do I not have the right configuration?

Thanks

What are all the devices on your network? Do you have a modem/router from your ISP?

The modem I'm using is the Motorola surfboard which I own.
Modem only, NOT the combo version.

Correct, extreme is connected directly to the modem.

Express is then connected to extreme

Is the Express a newer or older version? Plus is the Extress have NAT turned off since there is already A DHCP service in the main router?

The express should not be doing NAT! Get into that router and make sure it is in"Extended" mode to turn off NAT in it!

Hi Jedi5,

1. if your Express is connected to the Extreme via Ethernet, and if the Extreme is your router, then the Express must be configured that way :

Wireless : "Create a wireless network", with same SSID (wifi network name), same security (WPA2), and same password as the Extreme
Internet : connect using DHCP
Network : router mode OFF (bridge mode)

2. If your Express in NOT connected to the Extreme via Ethernet :

Wireless : "Extend a wireless network"
Internet : connect using DHCP

Setup 1 is much better than setup 2.

Awesome!

This did the trick.

Thanks both for your help.
