Been getting packet loss for a while so decided to start a think broadband graph.

BQM is poor - possibly because your upstream qam's have dropped from the usual level of 64 on each channel

Can you post up the Network Logs as well

had an outage from around 6.30pm-9pm today provided an updated BQM for the rest of the day. Need to setup a new one as WAN IP has changed.

Upstream power levels have changed but not so much the qam if that might be the issue.

Concerned about the logs, nothing really there and the date is all wrong. Everything is showing as 01/01/1970.

Upstream power levels are very high and the qam is dropping from a "normal" 64 and you have too many T3 errors. You will need a Tech visit to correct this.

Call it in and see what they say - or a VM person will respond on here in a day or so

Hi Semerson, 

Thanks for your post.

I have managed to find your account and can see your hub is not contactable for me to check your stats and power levels for today, can you please ensure it is switched on and modem mode is off so we can check this for you.

Zoie

Hi Zoie

Hub 3 has been in router mode since I opened this thread as it's normal practice not sure why you can't contact it. 

 

Today's BQM

Hey @semerson,

 

Thanks for confirming. We'll need a tech visit to look into this as we are unable to retrieve the data from your hub.

I'll just send you a private message to confirm some details and we can get this booked in. Please look out for the purple envelope at the top of the page.

 

Kind regards,

Hey @semerson,

 

Thanks for coming back to me via private message. This is all booked in for you and one of our engineers can take a look over things and hopefully resolve this issues swiftly for you.

 

The appointment can be viewed via your online My VM Account and you can change the date/time there too if needed.

 

Keep us posted!
