Unicast Ranging Received Abort Response

Hi losvigils and welcome to the forums! With that error and the drops in connection, the first place to start is usually to check connections; is the coaxial cable unkinked and unbent? Are the connections at either end snug, but not super tight? You can also do some rudimentary troubleshooting through the My Account for business app or portal: https://business.comcast.com/help-and-support/accounts-billing/comcast-business-services-online-troubleshooting/ . If none of that does the trick, please click on my handle (Comcast_Gina) and send a private message with your name, the business name, the complete service address (including city, state, ZIP, suite number, etc), and the phone or account number and I'll take a deeper look into the modem's signals.
