Question about usage

[#1]

My  usage screen is saying I've used 6.2gb for gaming off peak this month.
I never play online games, and certainly not after midnight.
Is this a miscategorisation by PlusNet, or might I have a problem with being hacked?

If you have a wireless router, then yes hacking is possible if you haven't got your security set up. You really need to make sure you are using WPA/WPA2 encryption with a strong password (ie. not a dictionary word or name etc) such as a mix of numbers, letters and other characters if it allows.
It is also possible to mis-classify, have you beem watching youtube, or iPlayers etc off-peak?

Thanks. I have security (WPA2) enabled.  No activity bar P2P off peak.

Hi there,
I suspect it's occasional bits of p2p traffic being misidentified, it's not anything to worry about (in fact if it's identified as gaming it'll be in your favour). I don't think it'll be anyone else using the router.
