My DSL modem is a Siemens SpeedStream 6520
The modem has its wireless function turned off...
The Router has WEP protection enabled b/c the WPA cuts the range too short so I couldn' t connect wirelessly.
UPnP is off b/c it interfers with just portfowarding and/ or DMZ increasing the NAT level to Moderate.
IF anyone can help me plz do.

Thx

The Solution: (for those who don't want to read to post 3)

Alright I fixed the problem.... here's some advice for future ppl that come here with a similar problem.

For the guy who tried I appreciate it, the thing is that the WRT54G does support multiple devices as long as you have the UPnP on. The reason I was having trouble was b/c I never tried this config after I received a new modem.(B/c the first one was giving me NAT problems)

-If you're having network problems or in other words don't have open NAT bring a TV and xbox (preferably a 360 b/c it is easier to diagnose with) up to your internet modem. Hook up the xbox directly to the internet modem and see if your network problems are gone. If they are then its your router that's causing the problems, if not then its the modem and you need to contact your ISP for a new one that is recommended as a compatible device by xbox/Microsoft Compatible Devices ISP(Internet Service Providers) usually will try to troubleshoot the problem, just stick with it until they give up and send out another modem.

- Verify that your router is compatible, if it is it most likely can route multiple devices (like two xbox 360s) If it isn't compatible, replace it with one from the list Compatible Devices

- If it is compatible and you have UPnP you want to enabled UPnP and make sure that the port forwarding and DMZ functions on your router off b/c they'll interfere with it. You can access your router by using its IP address. If you don't know it then look it up from the company that you bought your router from. (Here is some common ones and ideas one how to find an IP address out Linksys routers are usually 192.168.1.1) Also make sure that your xbox configures its IP address automatically as well as it DNS sever. (so use all automatic options on your xbox)

- If the UPnP isn't working and you only need to network in one xbox, then use port forwarding of UDP 88 TCP 3074 UDP 3074. (the xbox live ports) In this case you have to assign an IP address to your xbox. The one that you assign depends on what router you own. (Linksys users usually assign 192.168.1.101) You can't network two xboxes this way.

- IF that doesn't work then you could try the DMZ, but I don't recommend it.

Most likely you will have fixed your network problems after the first two suggestions, but if you don't you can post here for help.

Also it isn't a bad idea to call tech support lines, but sometimes they aren't very helpful... hopefully the most help you get will be from me... But you can also try posting on The xbox.com tech support forums. I also tried posting on my router company's forums, but they weren't very helpful...

Good Luck
