Just a quick and boring one;

My cellular network data monthly bandwidth allocation is to run out soon as I've been teethering the connection from my phone to my lappy since the first day I'm here in Kota Kinabalu.

Was not able to use the lappy's WiFi, and so I tried to fix my lappy's WiFi by swapping the WiFi card (suspecting the one installed was broken),

but in the end I figured out the real problem was that I disabled the mini-pci slot of the lappy (the slot where the WiFi card is installed) in the BIOS to reduce battery consumption of the already broken lappy's battery. I also disabled Intel's Speedstep and that solves the problem of the 5 year old lappy not being snappy.
