i have comcast new gigabit fiber speed and have two modems with two ip adress is this normal it will go offline for some minutes and then return to normal there is internet as this happen randomly and technicolor modem is this normal

Also I can't understand your writing.

Did comcast provide you with a modem and/or router? Do you own your own modem/router? How long ago did you "upgrade" to a new comcast connection and did this issue just start after upgrading?

[Windows7ge]

You only need one modem/router. If the two routers are trying to lease addresses at hourly intervals it's possible they're handing out duplicate addresses. Duplicate addresses on a network is very bad. It can ruin communication for devices.

This depends. I have a modem and a router. Some modems have built in routing functionality but that is not the norm. (At least here)

Sorry it depends on how they're configured. If they're in parallel with the outputs plugged into a switch. That could be problematic. If they're wired in series it's less of an issue because the LAN on modem 1 would be 192.160.0.0 then after passing through the second router the LAN for the home would be 192.168.1.0. Of course this is not guaranteed. Every situation is different. This is just was is most expected.

here my account of comcast and this are force for fiber speed only in some cities s they sues this as adapter as they don't have ready the xb6 avance gateway modem

How are they connected together?

by the coax cable but they add one metal adapter as the tv outside but add it two cables to them as cox

If this was fiber you would have an ONT and they would be using Ethernet to plug in to a router. I know this because I looked in to the Comcast Giga pro service. My guess is your on Comcast's new Docsis 3.1 Gigabit tier, which should be 1Gbps down and 35 Mbps up. 

 

Looking at your setup. You have an digital voice modem (For Voice only) and a standard cable modem. I just confirmed yours is a DOCSIS 3.1 modem. The issues with DOCSIS 3.1 is the tolerances on where the signal needs to be is lower and Docsis 3.0. Can you post your signal levels from your modems diagnostic page? 

 

Im thinking your signals are just not good. Part of the issue is, your having to split the signal to a second Modem. In a good setup you would only have 1 modem. I dont think any DOCSIS 3.1 digital voice modems have been released yet though. My guess is your signal is split too many times and the signal is not getting to the DOCSIS 3.1 modem in the way it needs to be.

were do i test it

You have to access the modems diagnostic page. Not sure how to do it, in an environment with two modems. Normally to go to 192.168.100.1 in your favorite web browser. Then there should be a signals tab. You just need to copy and paste those results. But its hard to say what modem you will be accessing when going to that address as you have two modems.

Your upstream is a little on the high side. For DOCSIS 3.0 service the max is 52 and for DOCSIS 3.1 service its 50. Signals can change 3db during the day depending on temps outside. My guess if your signals are swinging out of spec. 

 

Firstly what you can do yourself. Check the wiring and make sure it all looks good. Check all connectors. You might even want to unscrew your wall plates and make sure the cable on the other side is tight. Remove any unnessary spliters between the main line coming in and the modem. Proper installs tend to have a two way spliter or an unbalanced 3 way spliter on the main line. This is limit loss going to the cable modem. 

 

If all else fails, call your ISP and get a tech out. It could be a bad line coming from the pole or a bad tap as well.

if i get one modem for everything can this fix it too

No, because your ISP will make you pay for Internet on each modem. Also, its a signal problem. Spliting the signal more will fuck shit up even more. Adding more modems mean spliting the signal. You need to figure out why the signal is messed up. Like stated, it could be a bad wire, connector or the TAP your connected to on the pole. 

 

The easy way is making sure all the connections are secure. Checking for bad wire. At the end of the day, your ISP is the only one who can fix stuff on the outside of the home.
