AC 1750 C6300 keeps dropping internet

Hello, our AC1750 C6300 keeps randomly dropping the internet. It's done this for about a week now. Firmware is up to date all the connections are strong. Troubleshooting ranges but the most frequent is "connectivity issues with your modem/router." We've had this model for about 5-6 years with no real problems and no real changes to amount of internet used.

Would really appreciate any feedback as to whether there's a fix for this or if it may just be time to replace. Thank you.

Have the ISP check the signal and line quality UP to the modem. 
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.


Any Wifi Neighbors near by? If so, how many?

Thanks for the tips, I'll definitely look into replacing the coaxs. I believe both the neighbors have a wifi setup. I can't avoid splitters unfortunately, could replace them though as they are fairly old.
