What will be an ideal response?
The first step in securing a Wi-Fi wireless broadband router is essential but is frequently overlooked. It involves "locking down" the device by creating a password to protect its internal configuration settings. Most wireless routers come preconfigured with a default password, and these passwords are well known by attackers. Protecting the router with a strong password prevents attackers from accessing the wireless router and turning off any security settings.
