On Friday (2oth April so IDNET inform me) I had over 1GB download whilst the computer was off at night.(also had over 2GB of download on Friday, even though was only using computer for email, light download (*.doc and *.pdf etc)).
I use a wireless router (had not set security on it).
Is most likely cause wireless use by others (i live close to other houses)?
Or have other people experienced similar large downloads whilst computer is off
?Any thoughts?

That sounds like someone was taking advantage of a free connection I'm afraid. :( You need to use WPA-PSK or WPA2-PSK, with a key of between 20 and 63 characters (opinion is divided on the exact number).
With the computer off, the router will carry out a small amount of 'keep alive' signalling, but it's never going to amount to more than a few bytes.
Get some GOOD security on that router,then see if it happens again.
Thanks
Have now fixed the security on the router - will see if that works
(have just noted that there was also over 2GB upload during the same period)
I have a SpeedTouch585 - how far do these things transmit???

Certainly looks like you've been used unless of course the usage figures are wrong.
It's quite common for people to be using unsecured networks without even knowing it for example I can pick up at least 4 in my neighbourhood as soon as I fire up my laptop.
As to the range it's a tricky one to try and answer obviously there is some degradation of signal through walls etc but still going off my own local experience I would say 50-100 metres unless all of them are hiding in my garden shed.
Do all you can to secure your network like
WPA-PSK as already stated by rik
Turning off the Broadcasting of your SSID it's also worth changing the name.
Change Username and Password to your Router
Enable Access by MAC Address only
No Wireless Network is 100% secure but by following these proceedures you will at least be a lot safer than you originally were.
Hi Neil
Like Jack, I pick up four other networks, two secured, two unsecured. I can log onto the latter two and, because they haven't changed the default SSID or logon to the router, I could create havoc if I was so inclined.
I have to differ with Jack on disabling SSID. I think it's much better to change it, together with the default login to the router - it makes it easier for you to connect to your own router, and harder for a hacker to work their way in. This (http://blogs.zdnet.com/Ou/?p=43) article may interest you.
MAC filtering can be overcome, but, used in conjunction with WPA-PSK and a strong key, is certainly an extra level of deterrent to the casual hacker.
As Jack says, no wireless network can be 100% secure, but like fitting good locks and an alarm to your house, you can make the casual hacker go look for an easier target.
