Intermittent disconnects

[hamont]

internet dropping sporadically

We upgraded our modem to a Rocket CGN3 a few weeks ago and had it bridged to an Asus RT AC-1200 router.  Almost immediately we experienced drops in service. We "rebooted" the router and modem by unplugging them both. That would fix things temporarily but the drops would start again. The firmware for the router has been upgraded recently.

Called Rogers multiple times, they would check the router, the speed, the area's service (Hamilton) and everything checked out as fine. I finally unplug ALL cables (Cat5 and power) from everything and waited for 10 minutes and plugged everything back in. That seemed to work for the most part. We still seem to have small service interruptions (10-30 seconds) occasionally, which seem to fix themselves. I've called Roger a few times and they can't offer a solution, they just blame my router which, prior to the new modem, operated flawlessly and never dropped anything (in conjunction with the old modem).

Can anyone offer any potential solutions?

Thanks

I am assuming that they did check your signal levels.. but  you never know ( have seen them NOT do it).

The newer modems, while offering more channels and capabilities, is a little more picky with the signal being perfect.

If your willing to log into the CGN3 and post the signal levels, we can take a peek an see if anything is amiss.

As that is the usually one of the main things that can cause it.

@hamont have you made any progress with the intermittent service problems?

[Datalink]

@et17 are you still experiencing problems with your internet and tv service.  I was rereading your posts which indicate that the cabling for you and your neighbours are located in your back yard.   Does that mean that the utility pole is located in your back yard and each house is serviced by its own cable from the utility pole?  Or, does that mean that you have a waist high green pedestal in your back yard and all of the cabling runs underground with each home using its own cable?  

From your comments you can do a couple of things. 

1.  Call tech support and ask the CSR to run a signal check on the internet modem and the tv receiver.  Let him or her know what you're experiencing in terms of internet and tv channel issues.  It sounds like you are experiencing a cable or connector issue.  There is probably a good chance that the signal check will fail and that the CSR would arrange for a tech visit at your convenience.   The missing tv channel problems should be sufficient cause for a tech visit.   

2.  Log into the modem by entering 192.168.100.1 into the address bar of your web browser.  That will work in Gateway mode or Bridge mode.  The only exception would be if you happen to have the modem in Bridge mode and happen to be running a router that requires a route thru the router to reach the modem at 192.168.100.1

When you have logged into the modem, navigate to the STATUS .... DOCSIS WAN tab, copy the Downstream and Upstream table, top to bottom all in one go.  Ignore the data that sits above the Downstream table as that is modem specific and shouldn't be posted in an open forum.  Paste that data into a post.  The copy and paste process will paste the text data into a post.  

If you call tech support please let me know the results of the signal check and whether or not the CSR has arranged a tech visit for you.

Hello Datalink, thank you for your response. I’ve tried to do as you said above with no success. I don’t have a separate modem. When I enter the above address into my web browser on my phone, it asks me for my username and password? What would they be? I tried using my network name & password, but it says wrong username.
You asked before about my lines to my house. It’s a green box waist high. The wires are for us and our neighbors buried just slightly below the ground, on our property. Now I’m no longer able to access Rogers on demand, Home Edition on my phone will no longer link up with my PVR. I’ve never had so many issues in my life. It all started when we switched and upgraded to the new PVR & had to change to the huge ugly white internet modem in order to get unlimited wifi back in November. We are still fighting with billing as they are still overcharging us. It’s been nothing but a nightmare!

One quick note, we received an email from Rogers the other day saying sorry for the interruptions in your area. No other explanation. So I guess it’s not in my back yard?

Support says nothing wrong with my internet, says an escalated ticket would be deleted.

I got my internet installed yesterday by 2 contractors. 
My internet had dropped roughly 8 times in a 24 hour period. It is very short, but happens.
I am on the same Ethernet cable I was on with my bell line that has 100% stability.

Here is my streams. And error log.

Yes it is still happening.
