Unacceptably Slow Performance

For the past few days, and various times. Afternoon, evening, and late at night, our connection in the house has been fluctuating at an alarming rate. I believe we are on the preferred or premier package, one that offers 20-30mbps down. For weeks I've been seeing speeds just barely hitting around 20.50mbps download (on the days it works correctly) only for the connection to spend most of it's time at terrible speeds on other days.

Example below:






We had a tech come out several months back (this problem has been present off and on as far back as late 2012,) couldn't find a problem, had no idea what packet loss was, etc. It was worth mentioning Cox had been doing line maintenance in the area both before and after the problem was noticed. After their "maintenance," I started seeing it get as bad as the following:




Is there anyone in the Hampton Roads area, specifically around Portsmouth (State of Virginia) experiencing issues like this? Can anyone at Cox shed some light as to what the problem might be? I've called the automated support number numerous times. I've power cycled the modem and router numerous times and checked all my lines and connections inside the house, it's nothing on my end, at least nothing I can do anything about personally to my knowledge.

Any assistance would be greatly appreciated! Thank you.

Could you check the modem's status pages at http://192.168.100.1 and post the signal levels and logs (if available) please?  There might be useful clues there.

At the moment, the connection is working as it should, I believe. But here is a screenshot taken of the signal page.



And here is the signal page. I know I unplugged the modem once last night to power cycle it in hopes of resolving the issues. That was around roughly 1 AM EST.

One thing I see from this end is the modme is reporting making excessive power adjustments trying to maintain sync with the signal.  One possible cause for this could be a power related problem.  Do you have the modem plugged into a power strip with a lot of other devices?  If so it might be worth trying to move the modem's power to another circuit if possible.

The modem was plugged into a six plug surge protector with the following items always being connected:

1. Modem
2. Router
3. TV
4. DirecTV box
5. Fan
6. Empty Slot (used for gaming consoles when played)

I have since moved the Modem's plug directly to the one open wall socket. Hopefully that will make a difference. I'll see if the issue occurs again in the near future, but thank you for the advice so far!

What can sometimes happen in that scenario is the connected devices require more power than can be drawn causing power on that circuit to brown out on you.
