Intermittent Connection

For the past week, I have been having an intermittent connection. I have contacted VM many times and they have found no solutions to my problem.

Here are the errors I have found in the network logs:

Is there anything that can be done to resolve this? I have suggested to the support team that I need an engineer to fix the issue, but they seem very hesitant in sending one.

Re: Intermittent Connection

Post up the rest of your hub stats! - Someone should be able to spot something!

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)

Re: Intermittent Connection

Downstream power is too high! That'll require an engineer visit!

Re: Intermittent Connection

Hi zainul,

 

Thank you for your post and welcome to the community. 

 

I'm very sorry to hear about the issue you're having with your broadband. 

 

I have been able to locate your account and have ran an initial check and nothing is showing as causing a fault. 

 

What I need to do is private message so we can confirm some data protection and proceed through some checks. 

 

^Martin
