I have been having this problem for a while now. during the day the modem is never connected, and the US/DS light flashes constanly. Usually i can get it to connect after a power cycle. Later on at night the modem connects no problem and stays connected. I have been through many modems mainly due to upgrading/changing my service. all have had the same issue.
heres the modem info -

I have seen the power levels get up to about 49 before...
These numbers are with one splitter installed. this splitter needs to be there. it is the 5-1002 MHz splitter supplied with the install kits from comcast.
I attached the system log fromthe last 90 days if it helps any.
