Motorola SB6141 Restarting Multiple Times A Day

After many years with no problems, my SB6141 has recently begun losing internet connection and rebooting 5-10 times a day. I have tried:

• Tightening all inside cable connections
• Unplugging power, waiting one minute, plugging back in

I have also compared my signal & log data to many responses on this forum but it looks okay to my non-network-savvy self. Appreciate any insight as to whether I should book a tech visit or replace my modem.
