How can I know whether someone is tapping into my internet wireless network?

Question

This is an IT question. I hope that someone can tell me where to click and such, to find out.

Answer 1

Put a security code on your network and you wouldnt have to worry about that

Answer 2

I m not Wifi savvy, but I have a bundle package and Internet, cable and phone is all included. Lately I ve noticed that any time I receive calls on my home phone from known callers, I immediately receive calls from unknown callers or names associated with the calls too (sometimes the names show up and it can be at 1 am, 3 am, 10 am, whatever). I ve changed my cell number several times (due to a stalking ex who changed the router password before he left and hacked my emails and monitored my Internet usage at the free wifi cafe across the street), and I ve noticed that when I used my cell, the same thing has happened, calls come in and this time I tried calling back, thinking it WAS someone I knew who didn t leave a message. Much to my surprise the number was blocked. I called whom I thought it was and the company said they never called me. I m beginning to think my wifi may have some sort of device that alerts my ex that I ve made calls and to send spam calls to my numbers? Is that possible? It sounds so far fetched, but it s so unreal that this is happening every time a call comes in or goes out that I m getting calls on my home phone, (the bundle company rep told me my home phone is being monitored by my ex on his computer, he isn t living with me now, but he s paying the bills), and now my new cell phone is receiving new spam calls every time I make or receive a call (I m responsible for that on my own)? All I can think is my wifi is being tapped and I changed the password twice on my router, but I couldn t change the wifi name on the wifi account. Help?

Answer 3

its usually called 'Attached Devices' (Connected Devices, Devices Connected, Devices something ect) in your router setup
if you dont know how to access your router setup, it probably will tell you in the manual, its usually at http://192.168.0.1/ or http://192.168.1.1/

'Attached Devices' will show you all the devices your router has assigned an IP to over DHCP, and usually show the device (computer) name

if you see a name that isnt one of your computers names, someone is probably tapping into your wireless network

though, if you have a WEP key enabled (which you should) there probably isnt anyone tapping into it, and if its not enabled, i suggest you do some immediatly (i tap into peoples wireless from my pocketpc all the time, its amazing how many people dont have it enabled)

(note: if there is someone on your network that shouldnt be, and you dont have a WEP key enabled, enabling it will automaticly disconnect them from your network, but will also disconnect all your wirelessly connected computers, untill you provide them with the key you have set)

Answer 4

Your router should have a list of connected wireless devices. If you have your sireless security set up, this probably isn't happening. In any case, where to click depends on your router. look for something that shows wireless devices, logs, or status.

Answer 5

There are many firewall that can tell you whether someone is connected to your wireless network or not. I saw that feature in PC-Cillin Internet Security once. So maybe you should try that out. I think Zone Alarm has that feature too. You can also disconnect them from your network and prevent them from connecting again.

Answer 6

There is no way to do that but there are "signs" :
-Your internet connection is slower than usual.
-it takes more time to load webpage and download a file.

I suggest you put a network key into your wireless network.
See the manual of your router.
Try 192.168.1.1 or 192.168.0.1 on your browser to access the router setting. (These are default for most routers, your might be DIFFERENT)

Answer 7

You can't tell, but you can secure it by password so if they are stealing your connection they won't be able to for much longer.

go to Start > Settings > Network Connections, and you'll see the wireless connection. I can't remember whether you right click on it or what, but it is pretty straightforward to set a password - just fumble about for a bit and you'll find it.

sorry I'm being vague, but this is from memory!

if you are using wireless router you can do several settings..
1- disable DHCP(dynamic host control protocol) settings and use Static ip...if you use static you have to enter a default gateway ip which is your router IP...and a subnet mask..
2- mostly the easy the easy way...you can enable DHCP and provide one ip range...in DHCP the router gives ip address to its clients..assume you put the start ip address is 100.100.100.2 and the end ip address is 100.100.100.2 this makes only one ip address availabe..then no one can share internet with you..
