Intermittent Internet Connectivity Fail

For the last few days but especially this morning I'm experiencing lots of periodic connectivity failures. Large enough to kill a Remote Desktop connection to my, um, other employer over in Redmond. Maybe 4 or 5 in the last hours. Other machines have had spinnning "waiting for website" at the same times. I've rebooted my "Comcast Business Gateway" once, problems still afterwards. Have been watching the "Cable Modem" tab to see if I can see that level of connection fail at the failure moments but no luck yet. Moderately annoying that when you press F5 there you get kicked back out to the home screen and have to nav back in and scroll around. Can't really use as "dashboard".

Anyone else in similar boat? Or just me?
