Wireless won't start up after reboot!

[earfer]

Hey everyone,

So what I'm trying to do is to get my wireless working again after reboot.
Here is the detail.

I have a laptop that connects to the internet (wireless), but lately I've been using a program call PMS (PS3 Media Server) which help me stream videos to the PS3. The laptop connects to the PS3 via ethernet cable.
Whenever I connect to the PS3 via the ethernet cable, the internet will cut off.

Laptop Internet --> Connect Ethernet Cable (That is also connected to the PS3) --> Laptop Internet *CUTS OFF*

[NOTE]
The PS3's IP Address is 192.168.1.10
The PC's Ethernet IP Address is 192.168.1.9
The PC's Wireless IP Address is 102.168.1.4

Then a friend of mine, gave me this code to copy over to etc/network/interfaces. This allowed the laptop internet to workwhile the PS3's ethernet cable is connected.

auto lo eth0
iface lo inet loopback
iface eth0 inet static 
    address 192.168.1.10
    netmask 255.255.255.0

But whenever I restart the computer. The wireless will not start up, leaving me with no internet at all.
The only way to get internet again is to reset the code that I typed in back to default and restart.

[NOTE]
My network device is all working, the problem is the mapping of the interface settings???

Thanks in advance~

Can anyone help me with this problem?

This is shown as solved, but there's no solution here. I've never been able to get networking going at startup in any of the 10.x releases of ubuntu. Any suggestions?
