I have onQ and my wireless router will not allow me access to the internet even when we are plugged directly into the wall, can't get on with xbox live either. I have unplugged and reset nothing works. I am thinking maybe its a setting in the computer?? Is this possible?

It may be the device you are trying to connect. shut down everything, unplug , remove batteries, plug in the ISP model, allow the self test, plug in the wireless device, allow it to self test, plug in, reboot the device, laptop, desktop, ipad, phone, whatever. You say you can connect using a Ethernet Cable? Just no connection wirelessly?

You can assuming all your devices support wireless. (Black XBox does). You may only get B or G wireless unless your devices support the N mode wireless. I will warn you that wireless on XBox can cause issues of lag while playing heavy network usage games on Xbox Live such as FPS's like Call of Duty. With the N150 you should also have wired ports in the back which would still let you connect wired devices.

What is providing internet to the RJ-45 Jack in your wall. If it is a college they may have port security turned on in their network which will not allow other Hubs/Routers to be plugged into the network.

Hi,

XBOX 360 is alredy wifi enabled you dont have to plug a thing in to it, if you want to configure wireless

All you got to do is turn on your wireless router/access point and try to search for available network in Xbox 360 and upon selectin the network it would ask for wireless key (WEP key cab found on the back or bottom of router) punch in the key and bingo...its done
Your box is ready to be wirelessly connected to internet and play online

alternatively if you dont ahve a wirelss router or you are facing difficulty is seraching wireless router or finding the security key

Connect the router to modem > then connect the router and XBOX with an ethernet cable
It will work

Else you can also try connecting the modem and XBOX with an ethernet or USB cable

(However in all the aboove scenario, please ensure the modem is getting the internet link through the normal RJ11 or phone cable, please dont unplug that else though your XBOX would be connected to Modem or router but it wont get internet connection)

1. Step 1 Have your Xbox 360 correctly hooked up to television with HDMI or component cables. Turn your television and Xbox on. Make sure your television is on the correct input. Make sure that your WIndstream DSL Modem is on. If you have a router, make sure that it is on.
   
2. Step 2 Obtain the security key for your wireless network, and write this key down. You will need this key to allow the Xbox 360 to have wireless access to the Internet. If you do not know where to find your wireless network key, you will have to access the security setup of your router. The way to do this varies by model, so check your user's manual to see how. If you don't plan on using the Xbox Wireless Adapter for your Xbox, you may skip this step.
   
3. Step 3 Run a network cable (Ethernet) from your router or directly from the modem to the Xbox 360. Once you have this cable plugged in you will have to access the "My Xbox" tab on your dashboard. Go to the "System Settings" portion of the tab, usually the last portion on the right, and access network settings. For wired setups, go to the "Configure Network" option and make sure both the "IP Settings" and "DNS Settings" are set to automatic.
   For wireless setups, you will need to have the Xbox Wireless Adapter plugged into the Xbox. Under the Network Settings, enter the security key that you obtained earlier to allow access to the Internet and Xbox Live.
   
4. Step 4 Create an account on Xbox Live. You will need to either have a credit card or an Xbox Live subscription card. You can purchase Xbox Live cards at your local game retailer. You will be asked to enter information and create a user name called a "Gamer Tag." This is the name that you will be known as in the x-box community hope this help you out
   

You can use your USB connection on your Cable moden for your Desktop PC and then bridge to another through that computer's Ethernet connection to another's Like your Laptop. you can go into your network center on your desktop and go to your connection's status, then go to the sharing tab and check "Allow other computers to access this connection to the internet" or such as.Thsi can work for you Xbox 360 as well, it worked for me

Is the main computer connected to the router or to the internet directly? If it is a cable modem for the internet, make sure you turn that off, as well as the router, and connect the cable modem to WAN on the router and put the modem on first, then the router. Connect the computers, xbox, etc to the router

Yes you can plug it in directly, i dont think youll need a cross over cable, you can use a router so you can share the connection between several pieces of electronics, if you get a wireless router you wont need ny cables. A router routes data between ether net cable allowing each line access to what ever is on the network.

First unplug router, turn off computer. Then plug ethernet into router then power up. Allow time for router to recognise internet connection and boot up completely. Then plug second ethernet into computer then power up computer. Allow enough time for the router to recognise computer and the computer to recognise router. You should be able to access internet within a few minutes. If not you might want to verify that the router is not outdated and fully functioning.

Make sure ethernet cable from XBOX 360 is connected to one of the 4 access ports on the back of the router.

-Connect your router to the wall and connect your laptop to the router using a cable.
-Use Internet Explorer and type the following line in the address bar: http://192.168.0.1

-Click on the WAN button on the left side of the screen
-Now you should see the WAN Settings Screen

-Click on the Apply button at the bottom of the screen.

-Let me know if you need more help with any of these steps.
-Good luck...and I hope this helps!!
