Internet keeps dropping on computer several times a day. Please help. :-)

While browsing or watching live streams our internet drops connection and we get just spinning. We shut off internet and turn it back on and then it works fine again. We had a tech out and he changed the router and the cords. Our download speeds are around 186 and upload speeds around 28. We just bought hybrid mesh wifi pods to put throughout the house, has helped some but still freezing and losing internet. Any suggestions?
