may i "tumpang" here as well

My modem and routers are all on the 1st floor and my TV is on the living room ground floor is there a cheaper way to connect the HyppTV set to the first floor?

will it be cheaper to get:

a) a very long ethernet cable or
b) buy a router and link it up to my other routher (as per sekinnie's recommendation)
c) buy power line plug (i'll need 2 right? 1 each for upstairs and downstairs)

please

so meaning buying 2 powerline plugs (those from Aztech) is the safest way but yet is quite costly (RM100+ each)

may I know anyone who uses HyppTV instead of Astro? Im planning to cut my subscription with Astro and use HyppTV only as my family and I rarely have time for Astro

any feedback on HyppTV?
