What is a good power range. What would be a great power range
I have a C6900 modem/wifi that when I enter the main page 192.168.0.1, I see "Good" on the Cable connection. Is there a Better or Great or Excellant entries available? My 24 download ranges from...
On the main page all you'll get is good or bad. Its not very descriptive.
Its hard to tell you with what you've put for ranges as all the details are need. A screen snip is better to help us. It sounds like your power readings aren't good and cox is probably right with that.
You don't need a new modem/wifi to fix it. Its usually a line issue either from cox or within your house.
1. Remove any splitters, amplifiers, 90 degree elbows, kinked cables from the line.
2. check all your connectors for corrosion, loose fitting, bad connections, cheap connections.
3. Check your coax cable for extended (long) runs, moisture in the line, corrosion, wear/tear, and kinks. replace them if there are.
One of the easiest things to do is to move the modem right to where the cable comes into the house and connect there. It reduces the chance of a cable/connector in the house causing issues. Cable companies are required to provide you with a good signal entering the house. After its in the house, its on the home owner to maintain within the house. So move it, and then check your signals.
here's a website with more info on signal strength. Its helpful with troubleshooting.

- Thanks Netgear Community,Here are some screen shots of my modem...maybe you could give me a insight to my ranges, and at least tell me what the numbers mean, especially the BAD ones. Of course, COX looked another image timestamp, than the one I'm sending you.I'm running a cat5e cable directly to the PC. There is one split-er coming out of the wall. I did tighten all the coaxial cables and then power restarted. Thanks for you time and info.. I also notice that not the same Channels numbers have the same power settings upon requeing the modem display....also, the Power units are different on the down/up and the up does not list any SNR! I'm not sure if the Inserted PDF file works here...I tried an Clipboard image insert that did not work so had to add it to a pdf file.***After posting, got an error....How do I add a file or a clipboard image to this forum??I get download power/SNR range -8.9/37.8 to -13.2/33.6. On the Upload side, I see ranges of 48.4 dBmv to 50.4.
So technically your power is within spec but its a bit low. Optimally its -8 to 8 dbmv for downstream. within spec is -15 to 15 dbmv. Thats why I say you're technically within spec. And your upstream is within spec to.
From the pdf it also doens't look like there's any errors. Have you tried taking the splitter out of the line for testing? if power levels significantly increase, you might need to replace it. also is it a 2 port splitter or how many is it?
Are you having issues with the modem?
What are they?
Thanks Netgear,
I started to read the link you sent about power levels and will continue to search.
I do not "feel" any problems with my modem, don't experience any dropped signals...an I'm on all day. My download speedtest ranges about 210-230+Mbps, but my downloads have dropped to 5-7, was 10+ a few weeks ago. Contacted Cox, and thy said my modem has issues, so I started to inquire my modem readings...Of course, I didn't understand the numbers. I did ping, tracert ran Pingplotter and read many Cox forums where so many people complained about speedtest and dropped signals.
I will investigate connecting my modem directly to the wall, requires moving a desk. Now that I have printouts, I can compare some numbers and maybe understand the numbers.
On another note...when posting to your forum reply box, I was not able to directly insert a clipboard saved image. Just got a blank screen. So, I created a PDF saved file and used the Browse below to insert. When I posted my reply, I was told that there was something in the body of the reply that had to first be removed...I accepted and continued. You said that the PDF file was sent and it was not the item removed. Maybe it was the failed image or something else? Just wondering about image...I see RichText, so could be text only?
