I had created a strong wifi with My WIFI Router,but my neighbor alway connect to it,how can I to keep him away from my wifi connection?
Did you use WPA2 with a strong password?
Depending on your network, you can mask out his MAC address and stop transmitting your SSID?
Try turning it off when you're not using it (its a pain I know but you can be sure he's not on it).
MAC filter (black list will prevent certain devices from connecting, whitelist will allow only specified devices to connect), change the IP range, set up WPA2 authentication with a long, complex password, hide the SSID. If your neighbor is STILL hacking into your WiFi (at this point it IS hacking), have a chat with them and encourage them to stop and that if they don't stop you'll press charges on theft of services
MAC Filters are useless to anyone with basic networking knowledge and the same to hiding the SSID. Securing with WPA2 is the best method for home users.
However, if there are other networks in the area that don't employ those techniques it makes those more likely to get attacked. In my case, I see no fewer than 4 other networks that are actually broadcasting.
I think you should disconnect your Wifi router, cancel your broadband, cancel your phone and turned off all electric appliances. Not only will you be safe from your Wifi stealing neighbor, but also from Chinese hackers and identity thiefs. Get off the grid man, it's not worth it!
True. But if this guy is more than a dirtbag not wanting to pay an Internet bill it is easily circumvented. Just stating the facts here...
