How to Check If Someone Is Using Your Wi-Fi.
Check the devices related to your router.
The first factor you would like to try to to is login to your router's
body console by typewriting its scientific discipline address directly
into the browser address bar -- usually 192.168.0.1 or 192.168.1.1
depending on that router you've got. If you do not recognize your
router's default address scrutinize this guide or just head to the
prompt (Start ; Run/Search for cmd) and enter ipconfig. The address you
would like ought to be next to Default entrance below your native space
association.
Alternatively, if you're on a waterproof, you'll realize the default
address by planning to Network below System Preferences. It ought to be
listed right next to "Router:" if you're exploitation local area
network, or by clicking on "Advanced…" and heading to the "TCP/IP" tab
if you're exploitation Wi-Fi. Next, purpose your browser thereto address
and enter your login details -- if you haven't modified the default
settings it ought to be a mix of "admin" and "password" or blank fields.
Here's a default username and arcanum list (PDF) you would possibly
realize helpful, however we have a tendency to advocate you alter this
after.
Once within your router's body console search for a vicinity associated
with connected devices or wireless standing. In my previous DIR-655 from
D-Link it's obtainable beneath standing Wireless however you will find
it as "Attached Devices" in Netgear routers, beneath DHCP shoppers Table
on Linksys routers, "Device List" if you're victimisation the Tomato
firewall, and so on.
This should give a table with the ip, mack address and different details
of each device presently connected to the router. make certain list
against your gear to seek out any intruders. you'll be able to ascertain
the MAC/IP address of your computers by getting to the prompt once more
and getting into 'ipconfig /all'. The mack address are going to be
shown because the physical address. i will allow you to figure it out
for mobile devices like smartphones and media players since i can not
presumably list all choices.
Taking action
The best and simplest resolution is to line up a strong password WPA2 or
WPA -- WEP is extremely straightforward to crack thus avoid that if
doable. There area unit another ways you'll be able to use to support
security, like shift off the SSID broadcast (which prevents it from
advertising the name of your network to near Wi-Fi devices) or setup a
filter for allowed or blocked devices by waterproof address. It will not
stop the foremost determined interloper however it'll slow him down.
That should be over enough for many users however if you wish to really
capture who's been breaking into your network it's doable to pinpoint
his physical location employing a tool referred to as MoocherHunter. you
will need to burn a Live CD in addition your laptop computer with and
walk around to trace down unauthorized wireless purchasers. consistent
with the program's description, it detects traffic on your network and
might notice the supply inside a pair of meters accuracy.
