wifi jacking

I have an option in my router software to check the currently attached wireless devices. don't you?

also i can set a fixed list of devices to be available to connect, which I did. So no "unknown" device should be able to connect anyways..
 
i have a problem with someone who has the same mac address as my laptop but a different IP and a different mac address as their host name... that's in my DHCP list.

I have an idea that someone figured my WPA password, spoofed my mac address and was using my internet. However, i've changed the WPA password to something very long and complicated, and it shouldn't happen again.
 
Added info:

set your router so it doesn't broadcast your SSID. then change your SSID and channel. that should be enough so that people dont know you have a network...
 
I've never understood the hide SSID option. If its hidden how do you connect one of your own computers to it? Or do you enable then disable it?

hi is there anyway I can tell if someone has/is using my wifi conection?

WPA isnt very secure, I hacked my own in an hour just to see how easy it was and i've got very little technical knowledge of this area at all (although WEP only takes minutes to break so it could be worse). I think it can be done much quicker by someone who knows what there doing. I think only allowing certain mac address to connect is a a good way of doing it, I think cloning a mac address takes more advanced users so you're much less likely to get stung.

I was under the impression that WPA was VERy secure in comparison to WEP. Is WAP now also considered poor also!? Find this quite amazing as I thought WPA was where the key changed all the time. How are these still being hacked?
 
I dont really know anything about the encryption. I saw a program on the TV where they showed how insecure wireless networks were. That there are simple on google that can break the encryption. So I searched and found one. I set it up and changed the encryption on my router without entering it on my computer, left the program running whilst other computers were using the network and about an hour later I had internet on my computer.

Your not getting mixed up between WEP and WPA are you? (WEP is very easy to hack I know using the right tools).

If you don't know the SSID you can't connect, simple as.

The signal is so damn poor on most wireless routers that anyone outside would struggle to connect anyway.

Nope, the program would break my WEP encryption in minutes, it was harder to break the WPA. I've just been reading up on it just now and I think its because the key changes, so needs a really fast processor + a lot of traffic to be flowing on the network to break it reliable, otherwise you just have to leave it to run and it'll get lucky.

Its worrying because if I can do it, what could an actual hacker do to your network! Still I suppose the chance of someone going to the trouble is very low so most people will be safe.

So you can just type the SSID into the network settings box and then it'll let you connect? Sounds good if thats the case!
 
Yeah, when I set up the router I told it to use network name "abcd" (for example), however anyone doing a wireless network search would find nothing at all.

I'm on my laptop now, I simply tell it to connect to the network called "abcd" and away it goes.

But using something like Kismet, you'd find the network and its SSID in a matter of seconds... so its fairly useless.

I was under the impression WPA could only be hacked with a bruteforce attack on the PSK - so choosing a long complex password would make it completely pointless to attempt.

WEP, on the other hand: 64-bit - minutes, 128-bit - not much longer.

How? The router won't answer any pings, requests etc. You'd need to know the name first, so are you telling me there's a program to cycle through every single combination of letters?
 
I turned off SSID and put in the settings (which were already in the PC) and it failed to connect.

Netgear DG834PN here.

...so I switched it back on :o

It still broadcasts 'beacons' at a rate of around 10 per second. Just because it's not advertising it in a traditional sense, it's still very much saying it was there. Otherwise how would your PC know what to connect to? If the AP wasn't advertising it was 'abcd' in some way, then it would never find which BSSID (MAC Address) to connect to and on which channel.
