Aspire A515-51G Wifi connectivity

Hi my A515-51G is continually having an issue where at random points in time I will be unable to access any website. The wifi shows it is connected and that the internet is available. Turning off wifi and then right back on solves the problem. Everything works fine the wifi connects to my network and all websites work fine for a while then the cycle begins again. This happens throughout the day. I have loaded the latest wifi drivers and I thought that made it better but today it seems to back to itself old self. I have tried forgetting the network then reestablishing it. I have run the troubleshooter all without any success. Not sure where to go next.
