Re: Connection Dropping.
 

How long does it usually take for a reply on the VM forum? Usually within 2 days i receive a reply.
But a Member of the Mod team questioned my upstream levels after tech visit they booked for me and have not seen a reply and it has been 5 days since.

Link us the forum topic?

Re: Connection Dropping.
 

Note the log entries on the SHUB1 VMDG480 are a month out, so those latest messages are from July not June. Error by 2 commonest error in computer systems. :)

Re: Connection Dropping.
 

hmm, not sure why they've not responded yet. Try just posting asking for an update.

Re: Connection Dropping.
 

When i initially reported the problems to VM on the 13/07/15, my network log was blank.
It was only until the day after the engineer arrived which was the 22/07/15 that two items was added to my network log.

Re: Connection Dropping.
 

These items have recently just appeared within the Network Log (Not sure what is going on with the date of them though! as they have just appeared!)

Answers/comments/observations/suggestions already posted on your VM thread!

Always worth a second or third opinion...... admittedly....

Re: Connection Dropping.
 

Thanks for the input horseman
Just thought i would provide a little update.
Also -VM are offering me a Free upgrade to up to 152, which needs to be ordered online through the customer portal for some unknown reason? - But both my set-top boxes last night rebooted themselves- around about 5pm.

I am not sure what has been done to adjust things as i have had no contact from VM regarding the issues i was reporting, but obviously something has been adjusted.
