Planning to subscribe unifi. Any new promotions for 2017?

i just ordered unifi today via internet. So im scheduling the installation to come on Friday.

So right now i noticed my house have 2 wall sockets for phone and internet. 1 at living room and 1 at family area at second floor. At the moment, i have 1 used ASUS modem lying around. (my boss gave it to me for free, he bought a new ASUS modem RM1k++) Question is:

1. Can i use 2 modems for my internet line? Thinking of one (TM provided) to be placed at living hall (together with hypptv) and one ASUS at the second floor. Because i think single modem will not be able to cover my whole house because of blind spot etc.

2. Can i ask the contractor to set it up my modems for me for free?

3. Can it be done with 2 modems or I need to resort with TM modem only? Or is it best for the contractor to set up ASUS modem instead of TM modem?

Sorry for noob question

I need to re-phrase my question. it's router not modem.

FYI, my house is UNIFI ready because i saw there's a box beside my DB box and one box thingy outside my house.

I just subscribed to unifi yesterday and the installation went smoothly.

I ran speed test immediately and the speed is 28Mbps. But I noticed accessing websites feels sluggish compared to my streamyx 4Mbps years ago. Mind you that FB n lowyat forum also slow so there no issue with US or Malaysia site thingy.

Anything I can do to decrease loadtimes of Internet browsing by tweaking my router or modem?

i have subscribed tu Unifi last week, am i eligible to get free 1 year iFlix as well? Tried to access it via my hp, says i need to subscribe it
