I know this doesn't sound like it should be the first step, but do it anyways. Trust me, It will work out in the end.
We have to change the internet properties so that your computer will share wireless internet with the Ethernet adapter. See pictures. They are in order as they should. They also have notes. After doing what all the pictures say, hit ok.
This is simple. Right click the Ethernet Cable icon in the task bar, and hit "Repair"
Pictures say it all.
Right click the non blurred icon. Then hit repair. It shouldn't have a red X though.
1. Go to start
3. Type in ncpa.cpl
4. Hit OK
Thanks for the help idogis1
If your xbox says it cannot connect to the internet, but it can to the local network, try turning your firewall off, it worked for me.
The Xbox 360 is a home video game console developed by Microsoft. As the successor to the original Xbox , it is the second console in the Xbox series. It competed with Sony 's PlayStation 3 and Nintendo 's Wii as part of the seventh generation of video game consoles.

The Xbox 360's successor, the Xbox One , was released on November 22, 2013.  On April 20, 2016, Microsoft announced that it would end the production of new Xbox 360 hardware, although the company will continue to support the platform. 
The Xbox 360 was released on November 22, 2005, in the United States and Canada;  December 2, 2005, in Europe and December 10, 2005, in Japan. It was later launched in Mexico, Brazil, Chile, Colombia, Hong Kong, Singapore, South Korea, Taiwan, Australia, New Zealand, South Africa, India, and Russia. In its first year on the market, the system launched in 36 countries, more countries than any other console has launched in a single year. 
The Xbox 360 began production only 69 days before launch,   and Microsoft was not able to supply enough systems to meet initial consumer demand in Europe or North America, selling out completely upon release in all regions except in Japan.     Forty thousand units were offered for sale on auction site eBay during the initial week of release, 10% of the total supply.  By year's end, Microsoft had shipped 1.5 million units, including 900,000 in North America, 500,000 in Europe, and 100,000 in Japan. 
So, you've decided to buy an Xbox 360. Good for you. There are some great games on there: Halo 3, Grand Theft Auto 4, Bioshock, Madden , and the list goes on. What you might not know is that there's more than one version of the same console and some of them have some very significant differences. Hopefully, this article will set things straight and help you avoid making what might be an expensive mistake.
The first thing to know is what any of the 360 consoles can do regardless of its SKU.
Note: Even among original Pro or Premium systems, there are divisions. The 360 Pro edition is split between three different hardware models. Know what you are buying to avoid machines with faulty motherboards.
The Xbox 360 Elite comes packed with a 120 GB hard drive. Your 360 can fill up fast, and with this roomy bad boy, you'll never have to delete anything ever again. At $299 dollars, it is the most pricey of the available models, but still a great value. Costing only one hundred dollars more than little brother Premium, the Elite comes with a $150 hard drive, making this a $50 savings.
Slim Xbox 360 replaced the Elite line. Here are the differences between the two:
