finding out if someone else is on my Network.....

by lightsout / January 27, 2008 11:26 AM PST

Over the past while I have noticed that my highspeed connection is slow at times. I am connected to a wireless router which is connected to my DSL modem. I have two PC's connected to the router by Cat 5 Ethernet cable and a wireless Laptop which connects wireless. I am wondering since my house is pretty closely build to the other houses beside me, is it possible that someone else could be on my network, connecting to the Internet through my router?

i would go into your router setup and make sure that you have the wireless connections set so that WPA encryption is turned on.

I would use a key from which is a pretty well random key you will get (hint: the more random the less likely someone could *EVER* get on your network)

If you don't have WPA and only have WEP turn that on (though this was designed to be secure a person can crack it in less then a minute because of faults)
(WPA has no faults that have been found so it would take YEARS to crack into it)

Let's say your WIFI is not encrypted or is using WEP. Then the person who is using your network could be using MACSPOOF or another software so it looks like one of your machines is using the connection.

This is why it's nearly impossible for most owners to figure this out. But there is hope in our forum sticky.

By moving to WPA, SSID broadcast enabled you will lock them out.

In reply to: yea

They were running OpenWRT and maintained they could tell. With the MAC spoofed and the name as well they couldn't tell if it was their machine or mine.

Time to not offer WEP?

Make sure that your router driver are correctly installed or not and check your cable port. If don't work properly you can reinstall the driver.
