    Xbox 360 - troubles getting IP address (updated)


    I'm trying to figure something out. Here's my setup:

    Internet -> DSL Modem -> Primary Router -> Secondary 'bridge' router -> Xbox 360

    My Primary router is setup in Access Point mode and is serving as the DHCP server for the network. My Secondary Bridge router is setup as a 'Wireless Ethernet Bridge". Both are setup to use WEP, same channel, same SSID, etc. The internet works fine for all wireless desktops and laptops. No problems picking up a signal.

    However, my Xbox 360 is connected via ethernet to the Secondary Bridge router, it has the DHCP server disabled so the primary router can handle it, DHCP lease time is set to infinite (but shouldn't matter on the bridge router, right?), and 'Use Internal Caching DNS Forwarder' is enabled. The 360 cannot connect to Xbox Live unless I force a Test Connection to Xbox Live". It goes through a process of verifying IP address, DNS, NAT, etc. Once this is done, the 360 is able to get onto the Internet and everything works fine (ports are forwarded and the 360 detects it as 'Open' NAT, aka none).

    I'm trying to figure out why the 360 does not have Internet access without running the connection test first? I've tried setting a static IP address on the 360, along with pointing the DNS at the primary router. However, this did not work and the 360 could not get on the internet at all. I've setup a static DHCP entry for the 360 on the Bridge router and tried on the primary router, to no avail. Hard coding an IP address to use on the 360 results in it not passing the connection test.

    Any ideas?

    UPDATE: I think it might be something to do with the MAC address I'm putting in to make it static. But that still doesn't explain why I need to force a connection test for the 360 to get online! If it didn't have a static IP, it should request one from the bridge, which should forward the request to the Primary router, which in turn should assign an IP from the pool. But it doesn't work.

    The 360's MAC address begins with 00:1D:*:*:*:*. The bridge router is showing the device list as: eth1 00:13:*:*:*:* IP Address: (this is blank) Name: xbox360 RSSI: -74 dBm Quality: 20 Noise Floor: -94 dBm.

    Obviously, they're not the same MAC address. Why is it not showing the MAC address I got from the 360's menu? I understand that on the Primary router, it might not show the 360's MAC, since the Bridge is transmitting the signal and it would show up as the Bridge's MAC...

    I'm lost and confused on how to get this working. This 'Wireless Ethernet Bridge' mode is a lot more complex and confusing than it needs to be. I can't even turn on the DHCP server on the Bridge router and let it handle the IP because the DHCP server is automatically disabled in this mode.

    Give WDS a try. My son connects his 360 to my WDS router and within 30 seconds he is on the net. I had no luck with setting up a wireless bridge, plagued with disconnects, no IP and so on. I switched to using WDS 1½ years ago and never looked back.

    The router defaults to displaying the WET node's MAC address instead of the true MAC address of the client PC (or XBOX) connected to that WET node. This behavior has been discussed at length in this forum, and most agree that it's just a cosmetic anomaly. Things should work.

    I used to connect my XBOX 360 with the primary router via WDS just fine, so you may want to give it a try if you continue to have problems with WET. (I've since switched to wired Ethernet and eliminated the WDS router.)

    One thing to note though if you normally have everything turned off at the XBOX end and only turn them on when you use them. I sometimes must turn the secondary router on first and let it establish the WDS link with the primary router before turning the XBOX on. Otherwise, the XBOX may request, and fail to obtain, an IP before the network is fully established.
