additional cable connection

[Avi07]

Hello all,

in order to work with my PC from work , I need to plug a cable in to it , my router in in the living room and the cable is not that long .....
so i got a tp-link N300 (300 MBps 2.4 GHz ) - Wi- Fi Range Extender that gets the WiFi from the living room and from this tp link I plug a cable to my PC , it works but not that good,
so my questions are :
A. could you recomend any better device ? 

B. how much it will cost to add additional "spot" in the bedroom in order to get a cable connaection ?
Thanks to all

Hello,

You can have an additional socket installed by a private technician. We can not give you the prices.

Unfortunately, we cannot give you any recommendations for private end devices.

I'm sorry that I don't have any better information for you.
