Not getting the speed I'm paying for.

I have been experiencing frequent drops and low speeds. I am currently paying for Internet Preferred 50Mbps down. I am only getting 19.72 mbps down and 6.58 mbps up at 9:30am on a weekday when everyone is at work. My understanding is that there could be a possible firmware upgrade for the model modem that I have , DSA321N. Could you please apply this to my modem? I am become increasing dissatisfied with my service.

update: 10/11/16 @ 12:19pm AZ time Download speed is down to 4.96mbps and upload is 2.66mbps. This is ridiculous!

Can you tell us if the speeds you are getting are on a wired or wireless connection.

Many cases I've noticed a big slow-down in wifi speeds the more congested the spectrum is.  There are ways of working with it.  Here's a decent guide: http://www.makeuseof.com/tag/4-reasons-wi-fi-slow-fix/

The 3212 is a mature modem, doesn't normally need firmware updates this late in its lifecycle.  More often speed issues are signal or wifi based.

Great suggestions but I have looked into all of the things in the article already. I scan my wireless network frequently to make sure there is no channel overlaps. Like you, I am also a CCNA and not your average internet user. All other devices in my home that are on wireless were powered off or unplugged and I was the only one home at the time. This is just a problem with degraded service. I have been noticing it for several months. Sometimes it was due to outages in the area. It became a real problem yesterday when I was working from home and my Citrix session kept dropping. Makes it very difficult to get my work done.

That definitely sounds suspicious here are a couple of questions that come to mind:

  • Do all clients/devices see the same speed issues?
  • Is the problem in effect when on wired connection (direct to modem)?
  • I'm not sure if Cox has locked out http://192.168.100.1 on the Cisco modems, can you check that diagnostics page?

You are probably aware of the standard troubleshooting methods for these types of issues.  Isolate each network/device transition and test pre/post.   I'm very curious as to the signal levels at the network demarcation or at the modem..
