Zero upload speed, intermittent connection issues

$

0

As of last night, I've been facing ghastly connectivity issues. The Comcast speed test shows excellent download speed but fails to register any upload. I'll have periods where everything seems to be working fine, and then will wait 20 minutes to send an email.

 

In Berkeley, CA. Using a Motorola Surfboard, which seems to be working fine as below.

 

Comcast is displaying no outages? Everything's been power cycled. 

 

Anyone got any information/suggestions?
