Disconnected from "Received Response to Broadcast Maintenance Request"

Hi, it sounds like there are some signal issues to the modem.  I'll check things from our end, please email the account information to cox.help@cox.com.  In your email include the name and address listed on the account.  We'll get this figured out.

Can you try testing a wired connection and see if it has the same problems?

Wireless interference doesn't cause T4's. What are you gateway's signal levels?

Have you had any success in solving the issues? Because, I'm having very similar issues. I have a Surfboard SBG6782 cable modem. I have to reset several times to even hope to get on line and then only one or two of my devices will be able to connect. This all started about a week ago. I've called tech support twice and their advice is to reset my modem and unplug it. Hasn't solved a thing. Below is my event log with MAC deleted. Have you had any success in solving the issues? BTW Wired or wireless give me the same issues

BTW I was just booted off again. Posting from my cell phone. My frustration level is maxed out. 

@RPVStone

I looked from this end and the modem is reporting poor signal levels.  Are there any cable splitters you can try bypassing to see if that helps?

The issue is not the wireless. My computer is hard wired to the modem.   I have tracked this for two weeks now. It has been very frustrating.

 

The only cable splitter I am aware of is at the cable box. There are four cables from the box into the house.

RVPStone,

I have not resolved the issue and it appears we are having the same thing. My started about 2 weeks ago. What about you?

I am not sure how the check the gateway's signal strength.

Every time this "Received Response to Broadcast Maintenance Request" appears in my log...boom disconnection has occurred.

Chris,

It happens with both wired and wireless connections.

Do you have cable or phone with Cox? If so, any problems there? In general, your signal levels are on the low side. I would suggest a technician.
