Connect XBox 360 to 3CRWDR200A-75 wirelessly

I am trying to connect my Xbox to my 3Com router wirelessly. The Xbox sees the router but can never establish a connection. I have tried turning firewalls on and off, the same with encryption and many other variations of settings. In fact I have been doing this for a week now.


Prior to this router I had another make which worked flawlessly via wireless but did not have an ADSL modem. So the wireless adaptor on the XBox does work and is in fact only a month old. I have tried a wired connection to the router and it works beautifully. Unplug the cable and it all falls down.


Signal strength according to the XBox is 100%. SSID is correct. I have tried using DCHP on as well as off with static settings. All these settings work wired but not wireless.


Please let me know if there is a solution to this issue.

Im trying to connect my xbox 360 to xbox live but its gives me an error about eh MTU setting being to low i checked the router page but i cant find the tab/button to change it.

Sounds like a firmware problem on the router. login to the router and check the firmware version against the latest from 3com - the router should be able to check automatically.
Double check the universal plug and play (uPnP) is enabled - it should be under security settings on the router.

I have a Cayman 3347w wireless router and I am trying to use one of the wired slots to connect my xbox 360 to the internet. the xbox will not connect. is this router xbox compatable?

Please try the following steps below;

To make a router connection to Xbox LIVE:
  1. Before you connect any cables, turn off your router, modem, PC, and Xbox 360 console. (Unplug your modem from its power source to turn it off.)
  2. Connect one end of an Ethernet cable to the Ethernet port on your modem and the other end to the Ethernet input port on the back of your router.
  3. With another Ethernet cable, connect one end to one of the router's Ethernet output ports. Connect the other end to your PC's Ethernet port.
  4. With the third Ethernet cable, connect one end to another of the router's Ethernet output ports. Connect the other end to the Ethernet port on the back of the Xbox 360 console.
  5. Turn on your modem, then your router, then your PC.
  6. Make sure your PC can access the Internet. If not, you may need to configure the router for Internet access. For help configuring the router using your PC, check the instructions that came with the router.
  7. Turn on your Xbox 360 console and sign in with your profile.
  8. If this is the first time you've turned on your Xbox 360 console, see Create Your Gamer Profile to get started with both the Xbox 360 system and Xbox LIVE play.
If you're unable to connect to Xbox LIVE, you can try to diagnose the problem right on your console. Go to My Xbox and open System Settings, then select Network Settings (setup XBOX using Automatic Configuration DHCP), Test Xbox LIVE Connection.

Hope this helps!
