Internet intermittently disconnects

So for the last few weeks I have been noticing that my internet connection randomly fails. I use both WiFi and Ethernet connection and the service will drop for a few minutes before connecting once again. Sometimes the outages last a much longer time than usual and has become disruptive in my gaming. I've tried resetting and restarting my modem countless times and the issue persists. I wish I could connect to my modem via its IP address, but I forgot that login info as well.

Any help would be greatly appreciated.
