After trying to contact Lian Li for weeks, with regards to obtaining an “Antenna Kit” for their Faraday cage, err, I mean Xbox 360 case , I decided to make my own.
Took one of the antennas from my old wireless router
Added the plug and socket so that I can still remove the RF module without having to de-solder.

Seems to be working great so far, but I may do this mod later, to see if I can extend the range even further WIFI-Antenna-Hack!
Fuck you, Lian Li ,,|,,
