broadband

How can i tell if someone is using my broadband connection? Thanks

first question is why do you think someone is using it?

have you got WiFi security enabled?

which router (make/model)

because you are asking the question - I don't want to overface you

you want a sniffer
first open a command prompt
typr ipconfig {enter}
connection-specific DNS Suffix . :
IP Address. . . . . . . . . : 192.168.254.1 - this is your PC
subnet Mask . . . . . . . : 255.255.255.0 - ignore
default Gateway . . . . : 192.168.254.254 - this is your router

I think the easiest to interpret is
http://www.networkactiv.com/NetworkActivPIAFCT Mv2.2.exe
But - it doesn't work with a wifi adapter - so you'll have to use a wired connection
d/l and install
http://www.networkactiv.com/NetworkActivPIAFCT Mv2.2.exe
click graphical packets mode
press enter

you'll get a real time map of what is talking to what
192 addresses are your internal network - if only you are surfing there will be your address and the gateway address

when you surf ... you'll get addresses that DON't start with 192

an alternative is Look@LAN

d/l and install

create a profile
(if your gateway is 192.168.1.254)
the range will be 92.168.1.1 to 192.168.1.254

it will scan your netwirk at fixed intervals ... and tell you what's connected - and will warn you when another address connects.

Thanks for answers.As i only use internet to surf and never download and have 3gb I always exceed my usage allowance.

[ACtheTROLL]

it depends what you surf
iplayer will eat 3gb in a few days
fancy sites also use a fair amount
utube ... blah blah

keep tabs on your useage
