We have had our Internet taken over by a P.I. It appears that there are two of our Belkin networks. One is real, and one is a shadow of the other. When we unplug our wireless, another with the exact same name accepts us in. Please help.

See the How to Ask page for help clarifying this question.If this question can be reworded to fit the rules in the help center, please edit the question.

Try changing your WPA key. Your devices shouldn't be connecting to the other network unless it has the exact same security settings and password as your wireless router. – Josh Sep 5 '13 at 5:52
Welcome to Super User! Can you explain a little more about your situation? Couldn't you just change your wireless network to another name (SSID)? – slhck Sep 5 '13 at 5:53
If it connects to the other that means your wireless is unprotected? – Magnetic_dud Sep 5 '13 at 6:54
If it were me I'd turn off my WIFI connection for a while and use a tool (like Wifi Analyser) to track where the fantom AP is based on signal strength. I'd then get law enforcement envolved - there must be laws against it. Another useful channel might be to find the IP address associated with the phantom Internet connection using as a starting point, and getting law enforcement to take down the culprit. (Actually I have more fitting ideas, but It would be inappropriate to expound them on this site - but think along the lines of turning the tables on him !!) – davidgo Sep 5 '13 at 8:36
There are no laws in the US that prevent this. You have the responsibility to protect your own wireless and your connection (such as encrypting the connection). This happens at airport all the time, and it is your fault of connecting to the "Shadow" wireless. – Mark Lopez Sep 5 '13 at 13:45

On most routers (also called a wireless) changing both the SSID and the MAC address is possible. This would also make your access point completely different than the "Shadow" access point (also called wireless). Consult your wireless documentation on how to do this. (I recommend this also because changing your SSID will prevent a couple of known security flaws from compromising your network)

Also adding a WPA2 key (encrypting your wireless) will also prevent your computer from connecting to the "Shadow" access point. This is a built in security feature of WPA2. Changing/adding a WPA2 key will prevent the "Shadow" wireless from shadowing YOUR wireless.

Whilst you have not said which model your Belkin device is I would agree with others here about changing the name, however I would strongly recommend you select to HIDE YOUR SSID which mean that they will not know your new network name. YOu can get more information from Belkin here

IMHO a more critial issue should be WHAT where there intentions in doing this ? Was it to just use your internet ? Or was it to capature your wireless clients data ? At the very least I would take this time to change all your systems and website passwords ( remember to warn your users as weel ).

security by obscurity is bad advice. hiding ssid doesn't help. – JackeJR Sep 5 '13 at 6:45
Hiding your SSID is bad advice - it can be found easily enough when your computer broadcasts its connection attempt. – davidgo Sep 5 '13 at 8:37
