Since you're losing your internet connections on both Wi-Fi and ethernet LAN devices, the issue seems more likely to be either your router's WAN interface to the modem, the modem itself, or the coax side of your modem. It is quite common for marginal crimped coax connectors, splitters, unterminated coax connections, etc. to cause issues over time. If you call your cable company and tell them you're having some internet issues, ask them to run remote diagnostics to your Rogers modem. They can run a number of tests and loopbacks between their equipment and your modem to determine the quality of your coax signals. Signal levels, SNR, etc. They should also be able to view modem logs that might indicate marginal connections in the past.
