I'm running the latest version (as of yesterday anyways) of Ubuntu Desktop 64bit, but installed on my laptop if it makes a difference. I had Windows 7 preinstalled when i bought it and it worked fine with the wireless from my house and bridging the connection with a LAN to my xbox for Live. Now with Ubuntu I tried the same setup, but I'm unfamiliar with Ubuntu so I didn't get far. Best I got so far is wireless internet on my laptop and a wired connection to the xbox that continually connects and disconnects.

Heres my network settings. if theres fields not included its because theyre empty on mine or theyre my MAC address or network password

Wireless Network 1 settings:
Connect Automatically: Checked.
Available to all Users: Checked

Wireless:
SSID: Franco's
Mode: Infrastructure
MTU: Automatic

IPv4 Settings:
Method: Automatic (DHCP)

IPv6 Settings:
Method: Automatic

Wired Network 1:
Connect Automatically: Checked
Available to all Users: Checked

Wired:
MTU: Automatic

IPv4 Settings:
Method: Automatic (DHCP)

IPv6 Settings:
Method: Automatic

Any help would be greatly appreciated.

EDIT: 6:26pm It seems to be staying connected now. Doing the Network test on my xbox it pickups the network, but cannot detect any PC. Restarting the Xbox, however, leaves my computer unable to connect bringing up the Wire Network disconnected 'blip' every minute or so again. Before I had restarted the Xbox it said "Connected 100 MB/s". Now it only says "connecting". I did have my computer and xbox on in this Wired Network Disconnected blip cycle for a long period of time so it may have finally connected, just without the ability to detect my laptop. I left for 2 hours or so in the middle of typing up the original question. I finished posting this when i got back and then tried to mess with it a bit again, in case youre wondering why i didnt include this before... I've said too much. Forgive my long-winded fingers :p
