OK. Thanks. Now just have to think of the wiring .
1) Becoz if i put my router at living room, i can use the smart TV box, then i have to purchase a wireless card for my desktop(In My room, Upstair).
Although the wiring come from ceiling i bet, it still need cover to conceal it.
2) if i put on my upstairs bed then can directly connect to my desktop. But it seems i wont be able to use the smart TV box.
(Not sure whether the smart TV box still can be use ,have wireless feature) Becoz my TV is in my living room only.
Headache

ask how yr neighbors do it.
some houses, the cable come from the house front to grdflr, some from the back to top flr.
that will determine how long the total cable run will be for where u want it to end with the BTU (modem) - the cost for u.
if your house is small, good chance wifi will cover nicely most places, incl yr pc upstairs.
but if it's large superlink 100x30ft... tough.
note the STB (unifitv box) will likely be in living room beside yr tv, will need ethernet connection; ethernet good for yr smart tv too.
if u place the router upstairs, u will then ask "how to do unifitv with wifi"
do not make the mistake of placing modem/router in a poor place only to struggle with bad wifi issues later.
