Hey guys, need some help please. Head office has sent us a bill for excess data usage of nearly $400, we have a 200gig spark business plan and pay per meg over the 200. We only have 4 people in this office and there is no way we have used over 400 gig. It happened just before xmas and they sent us a please explain email and we couldn't explain it but didn't think about it too much, but now this time they have just sent us the bill and asked us to pay with our own money as they suspect we are using it for personal use.
We all have unlimited ultra fiber at homes so internet is not an issue for us to be downloading movies or something of that nature at work, this is a copper connection at work.
Head office won't send us or help us with any logs of when the heavy traffic occurred, by how much and on what days etc.
Two of our PCs are windows 10 and I can see in the data log they have both used about 10gig each, the other 2 PCs are windows 7 and I don't think they have that feature? We also have our mobiles connected to the wifi but they are saying about 10 gigs each also and that's with home use included etc.
The router here is a Huawei HG659b with very little logs I can pull off it, (well that I can find in the settings)
Can someone help with some ideas on how we can track this data leakage, I just did virus checks on all PCs and they're all clean, I have changed the wifi password but we aren't really close enough to anyone else to use our wifi.
Is there some software that is recommended I could download to monitor the network traffic?
Is their some logs I can pull off the router and send somewhere? I called spark but because I'm not the account owner they cant help me at all.
If you have any suggestions or need any more background info please ask. I am the branch manager so now have to come up with $400 that I don't have.
Thanks
