SBG8300 Continuously Loses Network Connection We purchased an SBG8300 modem/router approximately a year and a half ago. Since we’ve had it, we haven’t had a month go by that the modem doesn’t lose network connection, reboot, lose network connection, & reboot numerous times before working again. There’s no rhyme or reason as to when it occurs (morning, afternoon, evening) and it affects every device connected to it. We’ve tried various things to solve the issue but it keeps occurring. I’ve had Xfinity come out to check it but they can’t find any issues. I’ve reset the modem on several occasions and even changed the network names but that hasn’t helped. I’ve changed out the coax cable to the modem & I even replaced all of the Ethernet cables going to and from the modem but no luck. I just recently stumbled upon the QAM Upstream Power Level solution. However, when I log into the modem settings, from what I can see, according to my research information, the power levels seem completely fine. I’ve attached 4 screenshots from the modem
