Wi-Fi connection problems

I just bought my Macbook Pro a few days ago (13 in. w/ Retina, Early 2015) and when I log back in after it was on sleep mode, I try to search something on Safari and the website doesn't load. I find that the Wi-Fi is searching. In order to reconnect with my Wi-Fi, I have to turn the Wi-Fi off and turn it back on and then it reconnects. Are there any solutions to this? My Macbook has a 2.7 GHz Intel Core i5 Processor, and 8GB memory.
