Cannot connect to Router after day or so

Seems like every other day I have to reboot my router in order to connect to it via IP or NetgearGenie. I get "Hmm, we can't reach this page" or from Netgear Genie I get "Netgear router not found or is not supported. Also make sure the devie is not connected to guest network of the router, and no IPv6 is enabled." I disabled windows firewall and disabled IPv6. I still get internet and I can still see the other device on my network via Network Map. I just can't connect to the Router setting. My password is correct, since after a reboot I connect fine, both by IP and Netgear Genie. ANy assistance or ideas appreciated
