Network connection issue recurrence

Hello - Hope someone can help me identify root cause of network issues i currently face. I have been noticing daily modem timeouts which leads to few mins of lost connection everytime it happens.

Please see modem logs below. I am not sure if its a modem, wifi router or external line issue. I cant do a direct PC to modem connection test because i wouldnt know when exactly this issue would occur or what would trigger it.
