Where did you see that message? Try to set static IP address on your XBOX. Go to Network Settings > IP Settings of your xbox and set it to Manual IP and type the numbers below

IP Address: 192.68.2.200
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1
DNS: Automatic

Reboot your router and xbox after that.

You must configure NAT (Port forward) in the router.

Step 1 : Check the IP Addressof the Xbox And take a note of it

Step 2 : Open RSP By typing 192.168.2.1 on the Address bar of the internet explorer

Step 3 : On the left side Click Firewall

Step 4 : Leave the Password blank and click Submit

Step 5 : Disable it And Apply Changes

Step 6 : On the left side Under Firewall Click DMZ

Step 7 : Add the IP Address of the XboX in DMZ

Step 8 : Click Apply Changes

Step 9 : Restart the Router

Step 10 : Test the Connection

after upload the frimware its goes to default setting then you have to re-configure it sir

I just got it and yes latest firmware as of end of mai has been downloaded

I suggest setting this up with a WPA encryption rather than WEP encryption. This should get ya setup without a problem. Also, I've noticed live to be a bit buggy since Christmas. If you continue to have troubles after trying this call 800-4my-xbox. The recording will tell you if they are having network issues.

I bet this helps!

DHCP Host name is what your looking for.
you need to name each item ie. psp as psp and ps3 as ps3 when you setup each item for connection. so when you setup or edit the settings for your ps3 on your ps3 you need to look for DHCP Host name and name it ps3. etc
do the same for all.
