I've been reading several threads to try to get help with my problem but I've got to admit that I am just getting a bit overwhelmed. I am not nearly as computer savvy as I can clearly see that most of you are.
Here's my problem:
In my home I connected a small network by means of a dlink router. While it has wireless my two computers are not connected wirelessly at all. The wireless was more for my son and his video gaming equipment.
Now (some time ago) when I got the dlink it came with the network magic so I loaded it which the trial has long surpassed but still have it on my computer and can clearly see the network path (ect.).
A few days ago I checked the network path and saw intruders. I'll be honest and did not have the security set up (I know my bad) but have now set up the wep key. Dlink tech helped me do this and we chose wep due to the fact that I didn't know if I could use the wpa (?).
Now I was informed that creating the wep would instantly kick off any and all wireless intruders BUT according to my network magic I still have an intruder. *grrrr*
The only equipment that is on in my house is mine and my sons computer... none of his gaming stuff is on (Wii, DS, PSP).
If what this network magic is indicating is true and I still have an intruder on my network I want to block them.
As I have mentioned I have been reading lots of threads on here and it's just getting a tab bit confusing to me as to where to start to rectify this problem so I am in need of some guidance.
What I would really like to do if I can:
First, Can I see who they are and what they are doing? Now from what I have read is that I can track some kind of packets but do the packets tell me what they are actually doing or do I need some kind of keylogger to do that - or can one even do that?
Second, I saw there is some program that can actually sent the remote computer a message (now wouldn't that show them!)?
Third, I want to block them and anyone else from using my network.
Any help with doing this would be greatly appreciated.
