I need to know what's role of the cables AUX and MAIN because i cut one

M a n i _001 - Reply

AUX and MAIN cables are antenna cables. In this laptop there are two antennas, MAIN and AUX.

If you have a soldering iron, simply solder the two parts of the cable you cut and everything is gonna be fine.

I also recommend using shrink tubing to isolate the soldered part.

Note : laptop can work without this câble, but WiFi speed and stability will suffer.

If you can't solder the câble or can't by a new one, you can try to use only main by pluggin the only remaining antena câble to MAIN and leaving AUX unlpuged.
