11-21-12: Initial release
WiFi running a bit slow lately? If your router is still using old security methods such as WEP, then there’s a very real possibility that someone has hacked in to steal your WiFi. Apart from the obvious fact that your internet will be slower, the hacker might be using your internet to do nefarious evil things – all of which could easily be traced back to you. So how you can find out if someone is using your WiFi, and perhaps more importantly – what exactly can you do about it?
Check the devices associated with your router
This method is 100% guaranteed to see any devices registered on your network, but not every router contains this valuable info. Log in to your router by typing it’s IP address directly into the browser address bar. In most setups, eitherhttp://192.168.0.1 or http://192.168.1.1 should work, or it may be written on the router itself, along with the username and password you need to log in with.
Once logged in, look around a section called Attached Devices or Device List. On DD-WRT flashed routers, this is under the Status -> Wireless screen. You will find a list of all the IP addresses currently being used
Monitor wifi network use
Of course, not all your devices will have helpful names, so you’ll need to figure out the IP address of each computer and WiFi device you own in order to cross-check them against the list. I covered how to find your IP address a few days ago when I showed you how to control your torrent client from your mobile. Don’t forget that an iPhone or Android phone will also have it’s own IP address if it’s using your WiFi, so you’ll need to account for those too.
Basic Security – Stop using WEP
Any router purchased in the last 5 years or so should be able to support a more secure authentication protocol, so log in to your router again and find the Wireless Settings screen.
Change the security options to either WPA or WPA2. WPA2 is more secure, but it’s incompatible with some types of devices.Chose the option that allows for both. Don’t choose the Enterprise option as it is designed for companies with authentication servers. When choosing your password, make sure it is at least 15 characters long, includes upper and lower case letters, numbers, and punctuation.
There are some other methods that people will typically advise you to take, that help ,but are not bulletproof.
Hiding your SSID: You can hide your network name so it won’t be seen, but freely available wifi hacking tools will reveal them instantly.
IP filtering: This blocks out a specific IP, but changing IP is as simple as refreshing the connection.
MAC filtering: More secure since it blocks a device via the unique hardware address that is given out when it’s manufactured, but again, anyone trying to steal your WiFi can easily “spoof” their MAC address.
So your WiFi is feeling a little sluggish? The truth is that someone probably isn’t stealing your WiFi. More likely your computer is running slowly, or your router needs rebooting. You could also try boosting the WiFi signal.
“Having survived its freshman hazing, the Zune is back for its sophomore revenge, and the iPod has every reason to be frightened. The Zune 4 (4GB, $149) and Zune 8 (8GB, $199) offer a leaner, lighter version of Microsoft’s full-size Zune 80 MP3 player (80GB, $249).
With a new hardware and software design, wireless sync capability, subscription music compatibility, and integrated support for audio and video podcasts, the Zune 4 and Zune 8 are poised to compete directly with the third-generation Apple iPod Nano.”
Now if you’ve been following iPhone news at all, you’ll know that one of the most sorely missing features of Apple’s all-in-one device is built-in GPS for real-time navigation with the GoogleMaps application. However, fear not, for there is now a suitable solution to this problem.
Navizon is a company that offers P2P wireless positioning via cell towers and WiFi connections for devices that are lacking a GPS module. Just last month, they released a version of the application for the iPhone, giving users a viable GPS solution to use in conjunction with GoogleMaps.
An important point to note, however, is that it is not as accurate as true GPS. According to those who have tested it, it can be as far off as a city block, or even fail to give a position at all in more remote areas. [http://iphone.macworld.com]
Despite this, it still has a relatively sleek and easy to use interface, and works well over a WiFi connection. It should suit the needs of a basic user, and is easier and less expensive than buying and carrying around a Bluetooth GPS module.
