My downstairs tenant is using my wireless connection (he knows my ssid and password), can he hack my network?

My downstairs tenant knows my ssid (wireless network name) and password, is there any way he can somehow get into my network and see what i'm doing? if so, how tecy savvy does one need to be to do this? and how would he go about this? If it's possible, i'm just going to tell him that my internet connection is slow, due to too much bandwith being used and i'll just change my wireless name and password. PLEASE HELP?





unfortunately, my brother gave it to him because he needs the internet





if i change it hes gona be like why did you change it i need it ...besides hes gona say hes paying and blah blah



It is possible for him to load spyware and keyloggers on your computers, but he would have to know how and your machines would have to be vulnerable.





Since you apparently know how to change the SSID and encryption key, I'll suggest you also do the following:





1. Stop the SSID broadcast. Just changing its name isn't enough: He's likely to try the new name.


2. Make sure Wireless Router Administration is turned OFF. This won't affect wireless Internet in the least, but it can keep your router from being hijacked out from under you.





And if he says he's paying, ask him where in the lease it says he can use your network?


Hope that helps.




Well, first of all.. if hes pretty tec savvy, he could sniff your wireless traffic whether he was on your wireless access point or not..using a sniffer.





and if he is connected to your access, he could potentially see and take what you have in your "shared folders".





you could change your accesss point password. which would prevent hi from accessing the files on your pc




Yes, he can possibly see the data you send and receiver from your computer.





How can he do this? With something called a "sniffer" tool. If he is smart enough to do it (most people are not), then he could download some software and compile the data to see what you are doing.




Well if he's paying what's the problem? he will only be able to watch your porn if you agree to file sharing.




If he is able to get into your network connection, then yes, there are freely available tools (one called Cain and Abel at www.oxid.it) that can be used to sniff passwords that you enter on websites and other data that you enter, without you even knowing. It does require knowing some terms and being a bit familiar with computers, but there are many tutorials on the internet for that one program alone. C&A is capable of gathering lots of info.


Also, if you are using WEP encryption on your router, you can easily be hacked by anyone in a matter of minutes since it is very weak. Use WPA protection if your router supports it.
