Connection over phone line

[tereu5]

Hi!
I was wondering if it is possible to get connection in the house by phone sockets.
The thing is ,
There is a cable modem and it goes wireless. But the connection speed is better on cable ofc. (got only 11Mb/s Wifi card). I am curious if it's possible to connect somehow cable to phone socket and to modem and then upstairs to connect Ethernet card throuhg another phone socket so i am not creating the cable web over the house.
Cheers
P.S I know i can get new WiFi card but still prefer cable

Yes, phone network is possible but its been overtaken by faster, cheaper and more reliable networking over mains power circuits. Your unlikley to find the equipment needed. Have a look at 'homeplug' power adapters instead
