I have just seen this post & am interested in any responses as have had virtually the exact same problem this month! There just does not seem to be any solutions to this but something seems to have gone wrong or is using data that we are not aware of! I have a post going above that I have posted today so will be keeping an eye on responses on this one too! It is so frustrating when you cannot see any reason for this, I am a very low data user! I have a 40 GB monthly allowance, I never go above 19 GB per month & have not changed anything!
I too am very interested in this. I have been a BT business infinity customer for nearly 2 years. I have *Never* exceeded my 100GB cap up until the 'surprise' bill last week. They stated I had gone over for Sept and Oct. I thought this was strange and picked up the phone.
The lady I spoke with stated that I had used ~110GB in Sept and 329GB in Oct! This was lunacy. My particular setup is a Linux flavoured box running as the firewall / gateway for the internal network and this connects directly to the BT Hub. All internal devices will funnel through this particular firewall host with the exception of - my children's tablets. Avvid youtubers, I was mindful that they may make a dent in the capped allowance. With this, many months ago I installed the BTWifi App. In my mind, this would mitigate the risk of them quota busting.
It bugged me no end, so I installed / configured vnstat to watch the linux box's external network adaptor. I have the following the usage over the past few days.
day rx | tx | total | avg. rate

Today, I called up BT and somehow managed to mess up on the IVR and ended up talking to different group and a fantastic chap called Steve. Great guy. He was able to tell me what he was seeing with respect to usage. He could not see today, but could see yesterday. He had 1.417GB ... My box tells me 436.67MiB = 457.88MB So there's a HUGE discrepancy right there!
So I thought, righty, connect up to the Hub and see what it says. Hub says ->
Internet Connection Configuration
Connection time: 4days, 08:11:14
Data Transmitted/Received (GB): 0.4/1.4
Which is closer to what I see, but somewhat less.
Also, he looked back at my historical information this year. 20 - 60GB was the norm pretty much for the previous months, and some of those included my youtube loving kids. The only explanation I can think of is that maybe they lumped in the BTWifi usage with my regular usage. But even still, 300GB... In ONE month. My kids would have tablet shaped eyes (looked at a web calculator - 50 hrs youtube is ~15GB -- src- http://www.three.com.hk/website/appmanager/three/home?_nfpb=true&pageid=281001&_pageLabel=P600193131...
Steve, one of the most helpful people I have ever spoken to advised I email the query to a liteuseage address. However, I have absolutely no idea how long they're going to take to respond or get back to me. I just know in a few days time, BT are going to take out the £££s for this highly questionable overuse. I, personally do not believe their numbers.
Any help would be greatly appreciated. This is driving me insane (and potentially, understandably, moving on....)
As a business user you need to post here https://business.forums.bt.com/
this is a residential forum
the wifi hotspot does not come out of your usage allowance you were miss advised there
It shouldn't but has in the past and was fixed by BT. The mods have said it was a one off but there was never any explanation of what caused it - I suffered high usage prior to the official problem where the usage was extremely close to my wifi usage so I am of the opinion that there is some problem where wifi can be misrecorded albeit on a random basis.
This is the relevant thread https://community.bt.com/t5/Bills-Packages/Broadband-Usage-Massive-Surge/m-p/1326723#M43582
Whilst the usage of BT WiFi on the "average hub" may be minimal, the thing with averages is they are obtained by looking at ALL values.
Our WiFi usage for example is almost always in excess of our normal broadband usage, hence well above average.
We got charged for exceding our allowance when the BT error highlighted in the previous post existed earlier this year because of this very detail.
