Apparently the Comcast network had a big upgrade on the west coast. Pull the power cord/reinsert it to cycle your modem (not the router.) Then do a speed test to see if you've gotten a boost. Maybe do a speed test first for comparison if you don't do them regularly.

Click the "begin test" button.

I averaged 35 down and 5 up before recycle. Now am seeing 45-50 down and 10 up. Nice upgrade! Thanks for the heads up!
