You should also make sure you block guest access to local network devices and prevent them from accessing your router’s settings, if those options exist. Some routers only allow open guest networks, which I’d recommend against, since they allow good-for-nothing rogues to snoop on your guests’ traffic. Answer (1 of 5): You mean like, if he wrote it down on a banner and posted it in his window Sure - it’s possible to see that, unless you’re blind, of course. Information can spread easily and if only one neighbor knows your WiFi password, you’re out of control. Look for an option in the settings called “ Guest Network” and set it up with a WPA2 password if you can. If you have ever given your WiFi credentials to any of your neighbors, don’t be surprised if they keep using your bandwidth. If you aren’t sure of the correct numbers, check the sticker on the bottom of your router or open up its user manual. Head to your router’s administrator page by typing 192.168.1.1 (or something similar) into your address bar. Instead, you should create a separate guest network that will allow them to access the internet but keep them separate from the other devices in your home. This will give their laptop or phone access to all the devices in your home, which means they-or any malware installed on their system-can compromise sensitive data on your personal devices. Log all your devices using the new credentials. The device must have a Broadcom bcm4329 or bcm4330 wireless. Change the password to something new and more complex and change the SSID name.

Ideally, you don’t want to give people access to your main WiFi network. Not every Android phone or tablet will be able to crack a WPS PIN.
