As Neo pointed out your signals are within the window of optimal operation, however ... your downstream power level is on the verge of being borderline.

To add to that I would also check for flucuation. From your last post I believe you are saying you are having an intermittent connectivity issue and that is usually caused by flux in a signal.

You can check that by logging into your modems internal signal page and monitoring for a few minutes and refreshing the page if it does not auto refresh. Looking for any sudden signal changes of 2 or more.]]> http://www.dslreports.com/forum/remark,18907019 Sun, 19 Aug 2007 16:01:52 EDT http://www.dslreports.com/forum/remark,18904019 Tecklord : I was hoping I would not have to call in but it seems as though I have no choice. I lose connection alot and seems to be ok at night. My node is way overloaded and my speeds are pretty low during peak hours but thats another story. Thanks for the help people.]]> http://www.dslreports.com/forum/remark,18904019 Sun, 19 Aug 2007 00:33:10 EDT http://www.dslreports.com/forum/remark,18903752 BBT IV : Call in for a service call, your signal levels are way out of balance. ]]> http://www.dslreports.com/forum/remark,18903752 Sat, 18 Aug 2007 23:34:32 EDT http://www.dslreports.com/forum/remark,18902323 neofate : Possibly.

Your Rx power level is slightly on the edge/borderline.

With a Tx of 40dBmV, it gives me the indication that your modem isn't behind many splitters,..

That information would help validate the need for a technician.

How many splitters, and of what type are between your drop and the modem?

Looks like maybe a 2way at most -- Unless your Tx powerlevel is 'extremely' low at the demarc.

What exactly is occurring, and at what intervals?

Again, the layout of your cabling and splitters from Demarc to Cable Modem will be of great help.

Also what speeds are you 'expecting',.. if that is an issue. Currently it shows you should be getting about 500K Down, and 50-60K on the upload.

or , on a speedtest -- 4000-5000 Download, and 400-500 on the upload.

I am guessing you are having intermittent connectivity issues? Is that the case?

Also, how does the power level fluctuate during the day vs the night? (Ie: Take a reading at 7-8am, and then one at 2pm, then at night if you wish) -- To see how much the heat is pushing the signal.. Trying to see if its pushing beyond -12dB, or if that's the 'limit' at the worst.

This might be something you can adjust on your own, if your lines going to the modem are out of wack, and/or splitters/ground block.

If you want,.. take your modem and wireless router (or modem and a laptop) to your groundblock. (Or run a new cable from the ground block straight to your cable modem (bypassing all existing cables and splitters) -- To get a reading of your signals at the Demarc.

What I'm driving at, is if your Rx power level is a bit low coming into the home,.. if that is the case, then a Technician definitely needs to come out and fix you up. :)

We'll help you try to sort it as much as possible from our end, but if the Signal is low coming from the Drop, then you'll need a technician. (Redundant, I know.. ;) )

Take care,

I have had bad luck with Charter lately and it all started when I moved into this area. The were great on the other side of town.
