That card has dual band but seems to be a problematic card.
Suggest change to ac 8260, but obviously must buy yourself, meaning got charge. Who gonna give free new card

Just went to service centre yesterday. I was told that the spec that we bought at retail price 4,399 one doesn't come with dual band wifi channel though, so have to upgrade manually.

I am looking forward to upgrade into intel dual band wifi 802.11ac 7260hmw + bluetooth 4.0. Seems like there will be an additional cost.
As far as I tried, the battery seems good about 3hours+ without gaming.
Btw, its hard to find DDR4 2133Mhz ram in the market though even in Singapore.
