Erm im planning to buy this. but i see alot people complain the wifi is terrible. always dc and very slow. is this true?

Mind to ask?

Which source say that Acer V Nitro is having bad connection when connected with WIFI?

I did research on some populate website like http://www.pcmag.com/article2/0,2817,2472500,00.asp do no mention weak wifi as they built with dual-band 802.11n Wi-Fi, which isn't bad, but will be slower than the 802.11ac found on most current systems.

My experience with this laptop, didn't have such problem.
Not quite sure with other Acer V Nitro owner.

No la, no such thing on slow wifi, dont trust all reviews la. It depends on your luck also. But i never heard Malaysia unit got such issue. Mine doesnt at least.

I think depend on which wifi card you using lo. For old stock I think they're not using Intel wifi card. So there's a problem on it lo.. New stock is using Intel wifi card I believe

My unit is the old stock with atheros card. 

no problem with my wifi reception, speed and stability thus far. I must admit, i, too was worried bout the wifi issues that i've read in multiple sites prior to purchasing the nitro. However, after owning it for nearly two months, i found none of that to be true. The wifi card is working flawlessly. My only gripes is still, the touchpad. Quite unusable at times. But..its an awesome product as a whole.
