Avoiding "public" network security

What's the best way to setup a home network? Why should I care about BGP?

Avoiding "public" network security

Well, first of all, I don't know NOTHING about informatic security, so please be simple to explain things, well as the title says I want to avoid some network security.
When you connect from a wired connection, or even if you have the network password, you cannot enter, unless the admin wants it.
So, I want to enter to the network without the admin permission, also, I used EtherApe with Backtrack 5 r3, connected vía ethernet, and shows me all the computers connected to the network.
Can you help me please?
PD: it has a WEP password.

First just to set the record straight. We can't support doing something illegal. So there it is.

Now, for educational purposes. We need some more information. Are you prompted with an additional login after connecting? You mentioned a wired connection and then said WEP down at the bottom. Paint the picture for us. Don't leave out any details.

I'm sorry.
It has some computers that are already connected by ethernet, but also it has routers to distribute wifi.
and no, no logins after there

Well in that case, nothing is stopping you from cracking the WEP password and getting in. I'm still confused on this part though:

If this a larger network you might be running into an ACL confliction. But I'm just thinking out loud for a moment. What do you mean exactly by that statement? How would someone normally get access?

If it were me. I would crack to the WEP key and setup and wireshark capture to collect a good segment of network traffic. While at the same time use a clean device (like a phone) and turn the wifi on. After a couple minutes I would try and connect. Once it's clear I'm not getting internet access I'd take the packet capture, decrypt it (since you have the wep key) and see what is going on.

When you connect does it show that you are connected with limited access? Does your internet browser redirect you to any other page than the one you selected (ie google)?

First of all: I'm trying to do it from the wired computers (so they do not catch me)
And nope, there's not a warning with "limited access", just "disconnected"

Create and use a custom user-agent for your browser. Preferably one matching the windows OS for which everyone else uses.
