How to Connect your Xbox 360 to Xbox Live with a Laptop or PC

Lately, I became utmost desperate to go online on Xbox Live and play games over the internet with other people around the world, plus watching online movies in HD Quality on my LCD TV using the Netflix service which now comes as standard on Xbox NXE(Next Experience). The problem on Xbox 360 is that it doesn't have inbuilt wireless adapter like Nintendo Wii and Playstation 3 which means one has to spend like $100 to buy the wireless adapter from Microsoft. Honestly, I never wanted to spend 100 bucks on an add on accesory and therefore was stucked at playing Single player games till now, it's been like 9 months on this mode.
Yesterday night at 3:30 AM, something got into my mind, I started thinking if my laptop has internet can't I connect it to my Xbox and make my Xbox internet enabled(Yeah you are right, I have got no Life).
This is what I did to connect to Xbox Live using my Laptop-:
1) Laptop running on Windows Vista Home Premium with Broadcom 802.11 G Wireless Adapter in it.
2) Got an Ethernet wire, with both end same just like we have ethernet wires in LAN.
3) Connected Ethernet Wire from one side to my Laptop and to other side to Xbox 360 Ethernet port.
4) Then went to Start>Settings>Network Connections.
5) Then in Network Connections. Choose Wireless Network, Right Click on it to go to it's Properties.
6) In Properties window, Click "Sharing Tab", Check "Allow other network users to connect through this computer's internet connection". Once you do it, it will ask you to select the network, choose "Local Area Network" since you connected your Xbox to your Laptop using Ethernet Port.
7) You are done, your Xbox 360 is now internet enabled and your are ready to dive into the Xbox Live world without spending 100 bucks on wireless adapter which has no other use than on Xbox.

I have tested this mechanism on Windows Vista laptop with G-Wireless adapter using Trendnet 802.11G 108Mbps Firewall router. I am not sure, will it be able to connect using Mac computer or what if your laptop has 802.11 n wireless card. But one thing is sure my 100 bucks got saved :-). Desperate times, desperate measures; mother of unholy inventions ;-).


Note: Try to reset the Wireless Properties to Non-Sharing if you gonna use Ethernet port(LAN) for internet at workplace or somewhere else, otherwise Ethernet port won't work and will be dependent on Wireless Network.
