Critical Signal Errors SB6141 Modem
Signal is dropping intermittently, several times per hour. I cleaned and de-oxidized my coaxial cable at the modem which seemed to reduce the frequency of the failures. Need to know if this is something I can fix or if this is something Cox needs to address? Please Help

Chris and Allen, thank you for the email support on this issue following my post.
The problem was not a 100Mbps router, but instead the wiring outside of the house.
Solution: Cleaned and deoxidized coxial connections outside of house (With DeOxit D100L).
