I have a c6300 WIFI Cable Modem Router and it dropps wifi daily

I have exactly the same problem. Bought one of these in June 2016. Netgear replaced it after I spent the $16 to ship my defective modem back. Now, the replacement unit has staretd droping OFF both the 2.4 and the 5GHz nets. Their support is really, really bad. They put you on "quiet" hold for a long time, and before you know the telephone line gone dead. The Item is still under warranty but you cant get them to talk to you about the defective item unless you buy paid-support after the 90-day free tech support! I will NOT BUY another NETGEAR product again.
