We've been having problems since 12:30am with our cable connection (130/10Mbps) going up & down every minute or two. Nothing has changed recently.
I've discovered that one of the downstream channels on the Cisco cable modem reports zero for both signal power and SNR. Internet still works for half a minute then the modem restarts the ranging process, presumably to try to reacquire the signal on that missing channel. It's been restarting all day.
Has anyone seen this issue before?
Any tips or suggestions for explaining this issue over the phone when I get through to VF?
