ENHACE SECURITY ON WIFI NETWORK
I have a network in my house and is configured by a router TL-WR940N and 3 AP TL-WA855RE and works properly. Constantly I am receiving an attack from my neighbor and has already hacked me on several times my network. I update in the last two years ago the firmware from all devices and change the security to filtered by mac address, hide the Wi-Fi, strong password for the Wi-Fi, disable all the possibilities to hack me but the "hacker" looks like has knowledge on how to disrupt my devices and network.
What can I do to protect my network and block the attacks from this neighbor?
Do I have to upgrade my devices to have a latest hardware version and change the router and Aps? Is there any advice you can give me to minimize the attacks and how and what do I have to implement inside my network?
