I have attached the error messages from my modem. I have bypassed the wireless router and still have the problem. My modem is a Motorola Surf Board SB5101. Any suggestions? It may work find for and then this starts. I will say I have used Comcast speed test and some times the speed drops below 1mb when testing but usually is above 20.
