Hi;
I hope that I am in the right forum. First post.
I have a a problem which I am unable to figure out and hope somebody out there can help.

Network setup:
ADSL modem : DSL504T : 10.1.1.254 : DHCP enabled
Wireless router: DI524UP: 10.1.1.130: DHCP disabled plugged into a lan port on the modem.
Vista Ultimate desktop : 10.1.1.100
XP SP3 Laptop : obtain ip automatically. Unable to assign ip as I plug it into a firewall (plugged into the modem) to connect to work server.
Xbox (old) : 10.1.1.101
Xbox connected to wireless network via DWL-G810 Access point: 10.1.1.135

I can FTP files across to the Xbox from the laptop via wireless. My desktop pc can't even ping the xbox or the access point.
I have disabled the pc firewall and anitvirus (not that I expcted that to work)but it is still the same.
The xbox shows as connected to the wireless network and I am able to ping and connect from the laptop.

Funny thing is I connected to it from the desktop pc for one day and then it just stopped working. I didn't download any windows updates, no firewall settings has changed except I had to untick the 'ftp from external network' in the firewall settings of the adsl modem and reboot as my desktop pc is also a ftp server and wasn't working.
I have tried reticking the ftp setting in the firewall and reboot but that didn't work.

I don't know what to do from here.

Thanks

I have now found that it may be something to do with the subnet. When I plug the laptop into the firewall it gets an ip of 192.168.xxx.xx I can then connect to the Xbox. When I plug my desktop into the firewall I can also connect to the Xbox because it gets an ip of 192.168.xxx.xx. The problem is I can't leave my desktop plugged into the firewall for security reasons. Which leads me to believe that it is the xbox whixh is on a different subnet. I have found 3 places in the dashboard where I can change the ip and have done so accordingly. The xbox shows as connected to the wireless network. Yet I am still uanble to connect from the 10.1..... pc's.
Anybody else have an issue like this? Oh yes, EvoX on the xbox.

Go Hawks!

When you changed the IP address of the XBox, what did you change it to? It sounds like the xbox is picking up an address from the firewall? I assume that the firewall is a separate box - can you provide some more details about that?

I changed the IP of the Xbox to 10.1.1.101. Same subnet mask and default gateway as the desktop pc.
The firewall is a separate box (fortinet) plugged into one of the LAN ports of the ADSL modem. It has a static IP of 10.1.1.1.
What doesn't make sense is that I can connect to the Xbox from the laptop when it is wireless (Auto IP of 10.1.1.103) and when hardwired to the firewall (Auto IP of 192.168.xxx.xx)
I have switched off the firewall so that it is completely out of the picture. The XP laptop still connects to the xbox fine but the vista pc is still a problem.
The firewall is completely out of the picture. I have set the laptop with a static ip: 10.1.1.110 and plugged it straight into the ADSL modem (next to the desktop port:))
The laptop and desktop is now on exactly the same setup just the IP's differ by a couple of digits.
The Vista PC can't even ping the xbox but can ping the laptop and access shared folders.
The XP laptop can ping the vista machine and access shared folders.
What is up with this?????

Please help.

If the wireless router has an ip address, it is probably running it's own DHCP server and operating as a NAT.

Put it into bridged mode, that should get rid of the NAT and allow the wired network to see the wireless one.

The DHCP has been disabled in the wireless router. It has a static ip which it gets from the ADSL modem as the DHCP is enabled in the ADSL. I can access the xbox when the XP laptop is hardwired to the adsl modem. The Vista pc can't 'see' the Xbox and it is plugged into the same modem as the laptop.

You mention in your first post a "DWL-G810" - does that have DHCP server that is also disconnected?

Are you able to put together a diagram of your network - I'm not following how everything is connected from what you've described.

Vista pc and XP laptop connected to ADSL modem. Both have static ip's.
Wireless router plugged into LAN port of ADSL modem. This is all in one room.
In the loung: the Xbox has the wireless access point plugged into it. Xbox and access point have static ip's. I can ping the xbox and ap from the xp laptop when it is hardwired to the modem or wirelessly connected to the network but not from the vista pc.
Please let me know if that doesn't make sense and I'll try uploading a diagram.
Thanks

You are correct in saying the Vista pc has issues. I need the Vista pc to connect as all movies and music is on the hard drives of the Vista machine and the laptop is used for work purposes, so no clogging up the measly 160Gig drive on it :)
Diagram coming soon.
Cheers

Do you have two xbox's, or is it switching ip address if it moves between the fixed and the wireless network?

I wouldn't expect it to change address, since the DHCP addresses are assigned by MAC.  That means if it is changing, it is seeing a different DHCP server.  At least that's been my experience.

No. One Xbox always connected wirelessly via the access point. I am unable to connect straight to modem because of location in the house.

So, are you having troubles connecting _to_ the xbox, or _from_ the xbox (or both)?

This will depend on the implementation of DHCP in use.

Both ways from and to the Xbox on the Vista pc. I am more concerned with the fact that I am unable to connect TO the Xbox FROM the Vista pc. I need to FTP from the pc to the xbox.
