Internet Loses Connection Constantly
I keep losing internet connection about every 5 minutes during the evening. It's almost like it resets itself and then comes right back for another 5 minutes. Gets very annoying after a while. I have the following modem:
Make and Model: DCI382R
It's something wrong with the internet or the modem as it happens with all of my devices (laptop, phone, iPad, etc.). Is there something I can try or do I need a new modem/router?
Thanks!

"Make and Model: DCI382R"
Are you seeing this on you Cox account page or bill? If so, I think that may actually be Cox naming for the DPC3825. Does it look like this? Also, is that the only device you have, or is it connected to a router?
"It's almost like it resets itself and then comes right back for another 5 minutes"
How do the change on the front during this process?

That is the device I have, and yes it is the only one I have.
I have not watched the lights on the front during the episode, but judging that but how my devices react. They disconnect, the network is unavailable for a bit and then reappears and I can connect again.

Are you using a wired or a wireless connection? I can take a look at the signal levels of the modem and check for any visible issues. Do you have any splitters connected to the cable outlet? Email us your account information, send to cox.help@cox.com.

DerrickW,
I am connecting to this device wirelessly. I do not have any splitters connected to the cable outlet.

It sounds like the wireless connection is dropping out randomly. How far away is the router? Is it in the most central location in the home? Getting a signal extender may fix the issue you are having with your wireless dropping randomly. How often are you losing connectivity?

One thing I see from here is the modem is logging interference on a couple of the wifi channels. Do your wired devices also lose connectivity? You may be able to work around some of the wifi interference issues by changing the channel setting in the router from auto to 1, 6, or 11 as well as removing potential sources of interference such as microwave ovens, cordless phones, baby monitors, etc.

How do I change the channel setting?

Here's a link to the manual:

Follow the links to the wifi section to learn more about customizing the settings including changing the channel the wifi uses.

I changed the router channel and saw no change in performance.
Any other suggestions?

Try scanning the wireless networks around you and see what channels and bands are in use, and try to pick the least populated ones. inSSIDER 3 or Netstumbler are good windows programs to do this, but there are other options for android or mac. Here is a good blog outlining how to get started.

I changed my to use channel 11, which no other networks were using. The next closest was 7, with only one network on that channel. Same issue continued. I watched the modem/router and it is not resetting every time. Just disconnecting and reconnecting.

It's not changing channels anymore at least. If you have a neighbor using channel 7 for wireless-G or N note that it would still slightly overlap the selection of channel 11 as how 7 uses 7-11. Selecting 11 would tell the router to use channels 11-15. That being said this is probably about as good as you can get for a wireless configuration. Are you seeing connection problems with the wired devices as well?

Just a minor nit / clarification:
The channel listed is the center channel, not the starting point. Channel 11 uses 9 through "13" (although very restricted in power past 12 in the US). Channel 7 would use the frequencies covered by channels 5 through 9. The person using 7 should not interfere if they are "nice" and don't have channel bonding running too. If they are running regular 20MHz wide, then there would probably be very minor overlap at channel 9 frequencies, obviously stronger overlap if you are closer to that AP. If running bonded (40MHz width), all bets are off.

Thanks for the clarification. Channel bonding (40Mhz width) generally relates specifically to wireless-N. One of the compromises made to get N finally ratified is that routers must self-disable this feature if requested to do so by neighboring routers due to interference. This will not be evident in the router's user interface.

If you're in an old house with two prongs, you may need a better ground connection. I had a similar issue.
When I moved to a three prong plug, with a good grounded wire, my problems were over...
