CM 700 Cable Modem drops connection - upstream LED flashing

I have RCN in Chicago abd the internet drops off multiple times a day. They say all is good on their end. Usually it will come back online after several minutes, but sometimes it requires a reset of the cable modem (unplug, wait 30 seconds, replug). When this happens the upstream LED is flashing, like it isn't able to lock onto an upstream channel. What can I do to fix this so that I don't drop connection in the middle of work meetings anymore? I've also attached the event log from the modem if that helps. 

Thanks in advance for your help!
