i've thermal paste already.. max go up to 75C instead of 80C.. idle at 43C-46C .. outside temp is 34C or inside my house probably higher~

for wireless card.. horns already replace it with better one.. dual band i think..

for wifi card, my advice is to use an external dongle (i think it's cheaper than MYR 150.00); unless if you wanna spend MYR 300.00+ for killer bigfoot wireless-n wifi card (the only ones that i think work fine :/)
1. 1202 (2 antennas; dual band; with bluetooth)
2. 1103 (3 antennas; dual band; wifi only; from our friend at ROG forum, 1103 can reach 300mbps with the stock 2-antenna setup in the laptop).

forget about intel 6235 or 6300. the driver has issues (i tried almost all of them); or there is something wrong at the bios level (wifi white listing).

edit:

to install wifi card is simple:

1. make sure you take a picture of the positions of black and white wires;
2. take off the keyboard and display panel (the display panel blocks part of the card);
3. take off the wires;
4. replace the card;
5. put the wires back on;
6. put the display panel and keyboard back to their positions.

you are correct. after looking around for clues and hints, i found out many are still having problems with 6235 and 6300. many pointed the root cause to be the drivers (but i suspect it might be other factors involved). that's why i do not recommend this to you.

fyi the issue is the connectivity not being stable (fluctuates randomly). some run at very low speed.

yeah i am still using 6235 for a number of reasons:
1. to me i don't feel any degradation of wifi access (not like others; many reported that it's below 40mbps; it's not in my case);
2. i am having 150mbps to 270mbps connection speeds. it's fine for me even if it doesn't reach the full 300mbps.

running 8.

edit: .ac wifi adapters have been released, like in certain models of g75vx. new aw 17 is using .ac adapter, too. maybe you can search for broadcom 4352, 4360 too.
