RunningMan: Have you ever had a previous Vodafone supplied modem that has since been given away or sold to someone else?

otherside: We've had the exact same issue with our connection. It started with strange upstream traffic (which I made a topic here about but really wasn't able to resolve in any meaningful way).

Now we're getting upwards of 1gb downstream, especially between 12 and 1 am, and it's happened with our modem OFF. As in off, no power. It's sporadic too, we might get a few hundred mb or 3+ gb.

Vodafone told us that the line sends "keep alive" data, which I understand. However, that's a ton of data to be burning through isn't it?

We're about to do the exact same thing you've done, and switch to unlimited so we don't have to unplug our router (which isn't doing a fat lot of good anyway). We've also got friends who've had the same problem, but Vodafone gave them the same answer - that it's their devices/computers/spyware/insufficient security.

Really has been a giant pain in the butt.

otherside: I can't speak for my friend's modem, but we're relatively new customers to Vodafone (from last November). We have a Netcomm router that was provided with our cable connection, although I'm afraid I can't recall the model number offhand.

I don't know then if Greg's checks are applicable, but we've been through the ringer with technical support, and I've tried every check under the sun (isolation tests, password resets, spyware scans, disabling network capabilities on all our devices). No real resolution so far.

robyndiane: It is now over 4 weeks since we first asked Vodafone to try to sort out the massive uploading on our wireless VDSL modem.  It was only when our October bill came that we realised something was very wrong.  Extra $233 of internet charges not seen before!

We used to have an 80gB plan of which we only ever used around 50 gB a month and this worked fine from December 2013 until late September 2014 when something changed and we started accruing close to 8,000 - 10,000 mB each and every day!  Nothing changed in our house with laptop, modem, ipad or iphones.

The laptop is only used for email and facebook and maybe the odd google question plus office word, excel etc and has never been used for gaming or uploading movies.

Despite hours and hours spent on the phone each of the past weeks while Vodafone try to sort out the problem, password changed, modem powered off but still no difference, still huge data even when the modem had no power for 15 hours out of 24 one day, several reports requested from Vodafone support, remote control of laptop to try to find the problem, nothing found, scans run, new scanning programmes.

Vodafone can see a couple of IP addresses that apparently are uploading huge loads of data but cannot tell us what they are.

We are thoroughly sick and tired of the process and the time and effort we have had to spend communicating with Vodafone and we are ready to consider a new ISP unless this gets sorted out immediately.

I have offered to go into the Vodafone office and meet Management who may be able to help and would be prepared to sit there until the problem is sorted.

Not good enough Vodafone!!!

We have done everything you asked us to do and still no resolution. 

The saving grace was after a week of trying to get it solved, I requested a change plan to unlimited broadband so that at least another $200-$400 on our usual monthly bill, would not occur any more.  It is costing us extra to have this plan which we never needed prior to this problem.

HOW CAN WE GET IT SORTED!  Robyn
