update your router's firmware... or use a firmware that allows to see device list.

I agree with you.

For those who care about security, they should use WPA2 with a strong key.

We kinda got off point though. My fault probably. :p

The point I was trying to make is:

If you are worried about people tapping into your wireless network and using your network resources, you should secure your wireless networking using the strongest means possible.

Rather than checking all the time who has come through the door, you should just lock the door and give the key to people who are authorized to enter.

that said i didnt do any harm to them nor leech from their router...

it's easy to tap into mac addresses.
but normally those "less tech savy" will try to access, if they couldnt then they would switch to another.

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.

Yes but why would anyone use WEP? If you are going to enable encryption use WPA.

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.

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.

As a start, download the Backtrack CD and play around with it.

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.

Encryption is still better.

MAC filtering is easier to bypass than even basic WEP.

Cain and Abel is windows only. Airsnort is 'multiplatform' though better on linux.

There's no need to use either of those tools in this case though.
