How to check if someones using ur wireless connection?
-
My internet has been really slow lately, and i suspect there are people tapping on my connection!
-
use mac address filter
-
No idea, but would like to know too! Maybe can post in Tech support.

Your nick suits you.
Back to topic, here's how to check:
1. Log in to your router. Don't know address, either refer to manual or do the following:
a. Start > Run, type in cmd and press Enter
b. Type in ipconfig /all and press Enter
c. You will see a Default Gateway address. Type in this address into your web browser (most common is Internet Explorer)
d. Log in when prompted
2. Browse around the settings, you will find one section called DHCP client list or something similar
3. Here's mine:
-
Not too sure about DHCP clients list as it is not necessary for clients to use DHCP.
Maybe if you can find something like 'Wireless Clients List'...? -

catch the piggybacker. haha

i usallu ask around to see if they ar using

near my house got i unsecured router. i managed to tap, access the router settings and delete my own mac address, at the same time i looked at the names of the owner's computers before i disconnected.
then i did a yellow pages search and found their address......
that said i didnt do any harm to them nor leech from their router... -
TS, if you confirm that there's indeed someone tapping your connection, you can always take revenge using Ferret and Hamster.

erm... isn't the simplest solution just to enable encryption?

The probability of that happening is very low.Originally posted by ndmmxiaomayi:It can be broken.
If he's worried about people tapping into his connection, most likely it's open.
If it is encrypted, even with just WEP, you're pretty safe. The chance that someone with the skill and desire to crack the encryption, would come along, is low.
If you really care about wireless security. use WPA2 with AES. No one can crack that in any reasonable amount of time.
It makes more sense to enable encryption than to constantly check if there are unauthorized users on your network.
Anyway, I suspect the problem is more likely to be with the ISP or wireless interference. I've been experiencing very slow speeds on Starhub.
To check for interference, check what's the signal to noise ration of your wireless connection. If you wireless client doesn't give you this info, download netstumbler and use that. -
Talking about using linux for cain and abel and airsnort, that would be a different matter! Gd luck.

Cain and Abel is windows only. Airsnort is 'multiplatform' though better on linux.Originally posted by Fire Star:Talking about using linux for cain and abel and airsnort, that would be a different matter! Gd luck.
There's no need to use either of those tools in this case though. -
Use Mac filter.
On the Outside it looks like ur connection is unsecured, but on the inside, no matter how u connect outside using an unknown wireless device, it will nvr work -
Encryption is still better.Originally posted by kenn3th:Use Mac filter.

MAC filtering is easier to bypass than even basic WEP. -
WEP is reasonably easy to crack even for script kiddies.Originally posted by Phaze:The probability of that happening is very low.

The six dumbest ways to secure a wireless LAN by George Ou

The only place where I disagree with him slightly is the part where he says WEP is useless. Although WEP is relatively easy to crack, I still think for the most part, nobody would bother to crack the typical home user.
The only reason to use WEP is if your wireless client doesn't support WPA. -
There's no Cain and Abel for Linux as far as I'm aware of. Linux has other tools to crack wireless networks, which you would find better than Windows.Originally posted by Fire Star:Talking about using linux for cain and abel and airsnort, that would be a different matter! Gd luck.
As a start, download the Backtrack CD and play around with it. -
Yes but why would anyone use WEP? If you are going to enable encryption use WPA.Originally posted by ndmmxiaomayi:WEP is reasonably easy to crack even for script kiddies.
I'm just saying that WEP is better than leaving your wireless open or using mac-filtering. But using WEP when you have WPA is like choosing a lousy cheap lock when you have a big strong lock available to you.
