Hi there fellow lowyat users!

I am currently using a Maxis Fibre 30mbps. My modem is set up in the storeroom at 1st floor of my house, and I hardly get stable wifi in my room up on the second floor. I'm getting 5 mbps on average, with occasional disconnections on a daily basis.

I am considering to buy a better router for better range and speed.
I am considering NETGEAR R6700 Nighthawk AC1750 Smart Dual Band WiFi Router (R6700). It’s quite popular overseas but I’m just concerned that it might not work in Malaysia. Should I be concern of anything?
Do kindly let me know if you have better suggestions on other routers! 
You guys rock. please help a brother out.

(I have attached my current set up).

Yeh, I know it's a common case, especially for IT noobs like me :\
Both modem and router is in the storeroom. It's the only place I can set them up.
It's a 2-storey house. I would estimate arnd 80 feet to my computer location.
Im just thinking to maximize my current 30mbps since I only get 5mbps on average.

I believe mine's a VoIP. the package comes with a phone line.

I'm more of a quality guy so if the product is good I'm willing to pay.
But if both performs at the similar level I think I'll take your suggestion to get the Asus router?

I'll also take suggestions from others to try locating my router outside of the storeroom (but I gotta get a longer lan cable to relocate the router ay).

Thanks for the suggestion, would you mind suggesting a dual band wifi adaptor to pair with it?

Thanks man.
I think a TP-Link C3150 v2 router + Asus USB AC55 adapter should work for me.
