Router or Repeater?

[broadbucket776]

Hello Everyone,

I have currently got a new ISP Connection and they gave me an ADSL Modem with Wifi. The problem is that the WIFI has really bad signal and barely covers a few rooms in my house. Anyway i have either two options. One would be to get a TP Link router that has a high range with 3 antennas and connect it to the current modem/wifi via Ethernet cable and keep it next to it to cover my house or i could get two Wifi repeaters and install them in different places in my house. What would be more efficient, easier to set up and give me a better connection and speed?

Thank you for your recommendations.
