Securing Your Wireless Network
A mobile device can connect to your wireless network wherever it is within range of the signal strength from your wireless router. This also means that other people may be able to access your wireless network so personal data security is important.
How Do I Select My Wireless Network Mode?
In general, a wireless network can be operated using three different topologies; infrastructure mode, ad-hoc mode and bridging mode. When a wireless network operates in ad-hoc mode, client stations are connected directly and no access point is required. Using this mode, a potential attacker can gain access to a client station easily if the client station is improperly configured. Unless there is a specific business need, the ad-hoc mode should be disabled on wireless devices.

How Can I Configure My Wireless Broadband Router Securely?
Change the default user name and password because they are often easily cracked by attackers. Some manufacturers might not allow you to change the username, but at least the password should be changed.
Disable SSID broadcasting or increase the "Beacon Interval" to the maximum.
Change the default SSID. The new SSID should not be named to reflect your name or other personal information, otherwise the information could aid an attacker in collecting reconnaissance data about you.
Whenever possible, WEP and WPA should be avoided. Instead, use WPA2 or WPA3 if it is supported on the device.
The shared key mechanism should never be used. Instead, a stronger mutual authentication as defined in the 802.11i standard should be considered.
Enabling MAC address filtering is recommended as another layer of protection.
Disabling the DHCP feature, if possible, is recommended, as DHCP makes it easier for malicious attackers to access a wireless network.
