Net Connection Bridging through laptop.
 

**Note: This is more of a record of an experiment than a request for help, but if you have any useful advice I'd appreciate it.**

Even though this involves an Xbox 360, I still think it belongs here because it has a lot to do with DNS configuring and IP addresses.

So here's my situation. My net connection is fed through a wireless router downstairs to the laptop in my bedroom. I know the connection quality is good because I can play online games with no lag on my bedroom laptop.

I just got an Xbox 360 and didn't want to pay €85 for the wireless adaptor accessory just to use Xbox Live, so I had an idea. I connected the 360 via Ethernet LAN cable to my laptop and setup wireless bridging between my laptops wireless adaptor and its Ethernet port.

I ran network diagnostics on the 360 and it passed the IP test, but failed the DNS test. I have a feeling I just need to fill in some extra ISP details somewhere in the config to get it running, but since it's very late here, I'll continue testing tomorrow.

I did this at a friend's house but the bridge for some reason disabled his wireless connection on the computer- so I tried Internet Connection Sharing instead and that worked. I'm glad; I didn't want to mess with settings for things I have no clue of.

Actually I run a usb cable from my dsl modem to my laptop, then the ethernet cable to the 360 with a bridge enabled- didn't have to make any adjustments to anything. Now WMC is another story...

But, yeah, try ICS- is there a difference between the two?

I guess the bridge method might be a bit complicated. I thought Internet Connection Sharing requires computers with the same OS or compatible. Not games consoles.

Edit

I set up Internet Connection Sharing and it just works now. Weird. Thanks.
