Weird ISP issue while uploading only. Access Communications.

[Rizzly]

Hello,

 

This might be a far shot but I am having a problem with my ISP and this question is probably more directed at people who have experience deploying an ISP network.

 

I live in a small Saskatchewan town and my ISP, Access Communications, recently switched from providing 25Mbps DOWN and 3Mbps UP to an amazing 450Mbps DOWN and 25Mbps up.

I opted to select a 350Mbps DOWN and 20 Mbps up plan as it’s a better value than the 450Mbps one.

 

The download speeds are consistently as rated. The problem is when uploading you get 2 minutes of 20Mbps followed by 1 minutes of 3Mbps then it bounces back to 20Mbps for 2 minutes, 1 minute of 3Mbps… and the cycle repeats indifferently.  This result can be replicated any day, anytime, 100% consistently.

 

I’ve done all the proper network troubleshooting trips within my house and its not related to my setup (with the possible exception of the modem? Its a Hitron CGNM-2250)

 

This exact same result has been replicated by another member of the community who lives a few streets away from me.

 

This attached graph shows the behavior – the peaks are 20Mbps and valleys are 3Mbps.

 

I’ve called the ISP and talked to a first level tech and successfully explained and demonstrated the problem and the case is being escalated to their Network infrastructure technician with myself as the primary contact for troubleshooting.

 

The issue I have is beyond identifying a problem and replicating it I don’t have any idea what direction to point them to resolve this issue.  Has anyone encountered a similar issue when deploying a network and if so what was the resolution?

 

My personal setup is as follows.

Hitron CGNM-2250 in Gateway Mode

Asus AX86U Router

All of my devices use Intel NICs - the desktop and laptop I used for testing are wired.

 

I've tried different network cables, rerouting the COAX away from power lines, and different computers - I'm sure its not my network because as mentioned before, someone else at a different house was able to replicate the same thing.

 

Thanks for taking your time to read this,

Sounds like some sort of DSL vectoring solution over LTE with 3 Mbps being the DSL base speed. Maybe there is an issue where the network infrastructure is not powerful enough. Did you already try disabling wi-fi on your gateway, that could be the issue as well?

I'm pretty confident that the service isn't over LTE in any shape because they offer rural internet that is specifically that. The service we have is a cable one that is also offered in all the large cities.

 

Yes WiFi is disabled on the gateway - when it enters gateway mode it automatically does.

 

I've tried using their Modem/Router combo with only one device plugged in hard wired and get the same result.  I also get the same result if I have their Modem/Router in gateway mode and use my own Router.

Is the signal coming over the phone line or cable as in tv? We had an issue years ago with our ISP, they ended up changing us to a different frequency because of interference. My cousin hat a worse issue where the upload dropped down to 36k (should have been 2 mbit) thus causing our CS sessions to be super laggy back in the day. The solution was to a new copper line from the house to the switchbox using commercial grade wiring. Never had an issue after that. I am not sure if this applies to you and how the internet comes into your home. I have a friend in vancouver on one of the smaller islands and they had to rewire the entire neighborhood 3 years ago. Luckily it was all private property so we did it ourselves, except for the last part that needed to connect to the mainframe.
