I have an Airport Extreme. I also have a Samsung Blu Ray player that I want to connect wirelessly to the internet. The Samsung recognizes my network, and I can successfully connect. But when I run a network test, it passes Mac Address, then IP address, etc. (meaning it is making a network connection with the password I input), but then fails on Gateway Ping. Samsung says some type of security needs to be dropped. Can anyone tell me what to change on my Airport Express to get through?

Dell, Windows XP, Also have a Powerbook

    I got zero help from Samsung, except that I need to contact my ISP. I contacted ATT and they could not help since I had the Airport between the ATT Modem and the Airport based network. I have a combined ATT modem/Router and thus a spare unused ATT Network. We were able to get the DVD connected to the internet via the ATT network which is where it is now. I prefer to have only one active network hence the question to the Apple community.

    When your AirPort was in the network configuration, was it configured as a bridge? Was it connected to the AT&T gateway by wire or by wireless?

    Not sure of what you mean by bridge. My Network is wireless. The connection between the Airport Extreme and the ATT Modem/Router is a CAT 5 cable.

    Sorry, by "bridge," I mean was the Extreme configured for Router Mode = Off (Bridge Mode) when it was connected (by Ethernet) to the gateway?

    The Airport router mode is set at DHCP and NAT. Given that the network, with 12 connected devices, works flawlessly I assume that these are the correct settings.

    Now that I have gotten into the inside of the Airport via the Utility app I think I am seeing router address that are far different than what I was using in my earlier failed attempts to connect the Samsung DVD player to the internet via the airport based network. There were 4 addresses I manually entered, in the absence off a automatic connection, on the DVD Player "airport" network set up screen as follows:

     

    IP      10.0.1.36

    SNM  255.255.255.0

    G       10.0.1.1

     

    DNS  10.0.1.1

     

    When I went to the ATT network,essentially eliminating the Airport Router, and successfully connected to the internet, the same addresses, as provided by ATT, were:

    IP       192.168.1.25

    SNM    255.255.255.0

    G        192.118.1.254

     

    DNS   68.94.156.1

     

    The "airport" addresses I see on the Utility app are more akin to the ATT addresses than what I was using in the Airport set up attempts. The only missing address on the Airport Utility app is the Gateway (G) address, any thoughts as to what may be for the Airport router?

     

    Is the bottom line the fact that I should have been using the Airport Router addresses instead of what appears to be a device address?

    ... and what you are seeing would be "normal" if you have two routers in series that both have NAT & DHCP enabled. The AirPort base stations default to an IP address range of 10.0.1.x. Most other manufacturers' routers have a range in 192.168.x.x. That's why you are seeing these values.

     

    The issue here is that you will have a "double NAT" condition. Not a very efficient way to operate your overall network. That is why, if you do use multiple routers that only the "main" router be configured for DHCP and NAT, and all other routers as bridges.

    Is the bottom line the fact that I should have been using the Airport Router addresses instead of what appears to be a device address?

    No. The bottom line is that you want to reconfigure your AirPort as a bridge. This way any network clients, connected to the AirPort, would get the same IP addressing as that provided by your AT&T gateway device ... and all of them would be on the same network.
