Constant packet loss and line drops

Kagato
Tuning in

Hi there

For the past 3 weeks i have had issues with the service dropping at home but as of Monday it started happening every day to the point where i'm now dropping the connection multiple times a day and sometimes for up to an hour at a time.  It was only happening at night originally but its started doing it during the day which is when i am working so its starting to attract the attention of my boss.

Running a constant ping test i can see sets of packet drops happening every couple of minutes, i cant stay conneted to my work's vpn in the best instance, at worst i'm totally offline for an hour at a time.  It eventually settles but then repeats an hour or so later, so even in my private life i cant watch tv, play games, listen to music or anything that requires an internent connection.

I have tried rebooting the router multiple times, did a factory reset, removed everything except from my pc and it is still occuring multiple times a day.  I've just finished a factory restore so it may not show all the data from earlier today.  Is there anything that can be done about this?  When it is working it is running at a good speed but with it being down as much as it is right now that really dosent matter.  At the moment my network log is showing the following:

Lots of T3 timeouts in there!

Can you post up the rest of the logs? Upstream and downstream.

Power levels all look within spec!

U/S a little high side

Are there any outages in your area?

The most useful and up to date info comes from the 0800 561 0061 number. Try that to see if there are any faults that the web service hasn't picked up!

Hi there

I called the number but there are no reported issues in my area, the service status page didn't pick anything up either.

Hang tight for a forum rep to get to it - they will be able to diagnose and send an engineer if needed!

Thanks for trying to help anyway ^_^  The internet was much better last night and i didn't notice any drops but again this morning i've started to get the odd one every now and then and this is how it usually starts right before i get mass packet loss.  Hopefully someone can see something on the router/network that i cant.  It does not appear to be effecting my neighbours so it might be a router issue.

Hi @Kagato

 

Thanks for your post 🙂 

 

I'm sorry to hear you've been experiencing drops in service, I appreciate this is frustrating and we apologise for any inconvenience caused. 

 

I've had a look into your account and I can't see any issues that could be causing the drops on our end. If the issue persists, I'd advise running a Broadband Quality Monitor which you can access here. A BQM will continually monitor the state of your connection and will record any packet loss or network drop outs. It does this 24/7/365 and keeps a visual record of your connection. We'd advise keeping this running for 24-48 hours in order to gather enough data. 

 

Please keep us updated on how the service performs and if you have any issues setting up the BQM just pop another post on this thread and we'll happily assist. 

 

Thanks,

Thank you for coming back to me.  It has once again settled for the time being but i'll keep this ready to go if the connection starts to drop again.
