If you log in to the router's URL then you should be able to see a list of those connected. Isolate those you know are your devices, then you're left with the piggybacker.

It should give a 'device name', so maybe he'll have named his laptop something like 'JIMMYS-LAPTOP'. Otherwise you have a MAC address there. However that wouldn't be much used to you unless you have a rough idea of who it is. It would require you to cross reference with the actual device.

Good time to change your WiFi password I'd say.

dont know much about all this stuff, but i changed my password and it still happening

allen175

are you using WEP or WPA as the wireless encription?

Eircom Netopia router by any chance?

qwerty1a

its WPA, I can see a MAC address and ip address but thats all

qwerty1a

no its a Thomson router

I think you can block the MAC address with the Thompson routers?

Try blocking the MAC address. It's a feature available in most routers so hopefully you've that option available to you.

OP how do you know someone has hacked your wifi? Are you sure it's not just your phone or something connecting?

Use ip address lookup to find the location. Google it as in on the phone.

i Noticed it slowing down, so i went to the routers page thing and there is 2 address that are on the wifi that arent mine as i only have one computer and they wernt there before and i dont use the wifi for my phone

The list will show devices that still have a dhcp lease, it does not necessarily mean devices currently connected. It could show stuff from the last several hours or more.

Did you change the password to a word that was in the dictionary?

Set security to wpa2 and use a random password.

You could try pinging the address to see if it's still active. Could even try VNC to log into that IP address on the off-chance they've a server running.

You have no idea what you're talking about.



OP open start, type network and click on the network button, if its another windows PC it'll show there, if its unchanged it may just be "TOSHIBA-PC" or similar but as above could say "Johns-Laptop" etc.

^ OP....you should do several things, create a very unique hashtag/password for your wifi, minimum 26 characters long, a combination of upper/lower case, letters and numbers and symbols such as @_ etc.

Create a whitelist, your wireless card on your PC/laptop has its own unique MAC address, add this address to the routers whitelist....this means ONLY the device matching the MAC address in the whitelist can connect wirelessly.

Other precations, mask your SSID - also create a unique SID only known to you such as Thompson_4453667 etc., change the default username/password to access your router settings. Ensure you are using AES encription + WPA2......change your wireless channel from default to a higher number.

Of your router supports it change to the 5Ghz band.....good luck!

Mac address filtering = waste of time. Hacker can watch the traffic and use one of the white-listed ones.

Masking SSID = another waste of time, hacker can still easily see your network.

Changing password to something properly random and using WPA2 is the only advice needed.

This doesn't make much sense. The OP has said that they have changed their password a few times now and are using WPA. I would ask, what "password" did you change? Was it the password for the wireless network?

What are the first 6 characters of the MAC addresses of both devices?

Are you 100 percent sure you don't have a wireless printer/laptop/netbook/phone etc connected up as well?

Most people arent proper hackers...most just see an open wifi connection and use it, while whitelist and mask SSID might not stop a poroper hacker it will hinder an oppertunist, plus....it cant hurt to do as i say, every little helps.

srsly78

You don't need to be a "proper hacker". Anyone with enough of a clue to crack the password can also change mac address.

It does not help, it just provides a false sense of security - and creates extra work. Explaining to guests about the "invisible wifi"? Hassle!

In any case, I think the OP is just imagining about being "hacked".

+1 on that.

Im using WEP, but last time i tryed changing the password i almost f''''d up so im worried i might mess the whole internet in my household, but i really do want to change it to something else. I know you go into IE then type the numbers and you go into netopia page. Then what do i do? I don't want to mess up.

I don't get why people take it so serious anyway because my neighbours wouldnt steal my internet connection as they already have one and anyway why would a hacker use my wifi when they're like meters away it can't be access able.

You're best doing it when plugged in by ethernet as you will be kicked off the network if you do it on wireless. Every wireless device will then need to reconnect with the new password.

God-damn Jimmy, get your own WiFi!

Or, you could turn the tables, do a bit of an ARP poison, grab his Facebook session and stick him "In a relationship" with Justin Bieber.*

That'll learn him.. **
