Hi, I have a wireless router and during the night I have noticed that both the wireless light on my wireless netgear router and the modem lights flash, like someone or something is browsing the web. Anyway I changed the key to something very long and cryptic, but it had no effect. I unplugged the only windows computer on the network (all others use linux and I did turn them off) and it still flashes nonstop.

What do you guys think is happening?

You might need to logged into your router and check if there are other wireless devices connected by the status menu.

Well, I looked at the attached devices, and everything appears to be correct. And right now there is a lot of activity.

What is your security method are you using WEP or WPA or WPA2?

It look like you got a suspicious person?

Try to use a more secured method encryption(WPA2)

Go to your router page

Go to Wireless
Under wireless network
disable or unchecked SSID Broadcast

Under Security Options

Check WPA2-PSK(AES)
enter a complex password ie P@ssw0rd06

and hit apply

Now when you hit apply you have to know the SSID and WPA2-password

To reconfigure windows to use WPA2 follow these steps http://www.dummies.com/how-to/content/how-to-connect-to-a-wpa2-protected-network-in-wind.html

see if it helps the problem

Thanks for the replies. First off just 1 week ago I changed the WPA2 encryption to a 60 character long code. So as far as I know that eliminates the possibility of being hacked by a neighbor.

What devices are currently connected?

Well, I recognize everyone of them except 1. And the first time I checked the attached devices it was not there, then when I checked again it was there, and has been since.

Does the router give any information or description of the deivce? You can download Advanced IP scanner and scan your network. When the rogue connection shows up do a port scan and see what ports are available. Post your results back.

Would that tool run in virtualbox?

I just looked and I don't see why not as long as the virtual box has a network connection configured for the network you want to scan. Another choice (if u have an android phone) is one I use daily is "Fing" for android. (Free on the market) just connect to the wireless network and run the scan from your phone or tablet (similar apps are availalbe for iPhone I'm assuming)

Well I don't really even understand what I am looking at. It says I have like 4 alive connections (counting my vb machine) but according to my router there are 5 wirelessly connected devices.
