I realize you're using the "Main" edition, but I have the same V2000 notebook. If haven't been able to resolve the networking issue and if you're willing to try this out, I'd like to say that the wireless networking in Linux Mint 13 XFCE (32-bit) version works perfectly. Wireless networking also works in version 14, but for me, there are other things in version 14 that didn't work so well... namely, MESA 9.x doesn't support our onboard intel graphics, and so we lose hardware graphics acceleration.
*Linux Mint 13 XFCE 32-bit (Until the next LTS release)
*Linux Mint 15 XFCE (RC) 32-bit (Tried...Failed)
