I an buying a used XBOX 360 from a friend and I am curious if the XBOX 360 can use an N wireless adapter instead of the standard B/G wifi? This will answer the original posted question because it solves two problems at the same time. It is wireless and N wireless is very fast (130 Mb/s).

Thank You for your help.

I use a 15€ wlan-router for my living room. You still have to use an ethernet cable to connect it to your 360..

I gave up on wireless for gaming cause it causes too many issues and is very unreliable. Now besides finding a good deal on a used 360 adapter(I got mine for $33), you can use a wireless router as an access point. The basic concept is to connect your router to another(wirelessly) and connect your 360 and whatever other game system you have to it via wire. You can use all of your systems with the access point(assuming that it has more than one ethernet port, which most routers have 4) if it gets better reception than the built in adapter for a PS3/Wii/PC.

Ebay usually has some in the 35-45$ area.

The solution I use is to go online wirelessly with my PC. I then connect the 360 to the PC using the ethernet cable and then use the PC's internet connection to get online on the 360. Means your PC has to be on of course but at least avoids having to pay for the ridiculously overpriced wireless adapter.

You saying that I can connect an ethernet cable to my laptop and then connect that cable to the 360 and go online?

That would be amazing! My laptop is always on anyways so it would be fine.

If what you say is true then I have to try that out.

change the following settings for hook up with an xbox or as a hub for a wired device.
connect with a wired computer (see instructions)
Basic setup
1.Station Infrastructure Mode.
2.Same Ch and SSID as your router.
3. I left mac address blank
click apply,
then go to security section and configure the wep (if needed) - you must do this step last, if you do this and then change the settings in the basic setup, it returns the security to disabled.

Change computer network settings back to automatic ip and it should work.

It should give you better network performance than the PS3.

Here's what you got to do.

Step 1: Connect the Xbox to the computer via ethernet cable.
Step 2: Control Panel>Network & Sharing Center>Manage Network Connections (on side panel)
Step 3: Highlight the ethernet (local connection) & Wireless adapters.
Step 4: Right click>Bridge connection
Step 5: Game on.

This works, I've done it several times on my laptop and PC.

1. Control Panel
2. Network Connections
3. Right your wireless connection and select properties
4. Go the Advanced tab
5. Check "Allow other network users to connect through this computer's Internection connection."
6. Connect XBox Ethernet to computer or laptop, restart

That should do it.
