*Alter defualt user names and passwords for network devices.
*Use WAP.
*Alter default SSID for each access point device.
*Alter the default IP subnet.
*Stop SSID broadcast.
*Turn off DHCP.
*Enable Mac filtering.
*Adjust signal strength to bare minimum needed
*Disable or change Simple Network Management Protocol (SNMP) settings to prevent outsiders from obtaining personal information.
*Install firewalls for every computer.
Thanks in advance.
Although I agree with many of the rules, some of it is overkill. For example:
*Use WAP.
WEP is highly insecure, so WAP is a good alternative. As long as your devices support it. Many older computers and laptops still only support WEP, so you may be forced to turn down your level of encryption.
*Turn off DHCP.
Although it can be an easy break for a cracker if they can find your computers, you can enable DHCP safely. One way is not to use the default IP address ranges that your router is preconfigured with. Another (and far better way) is to use Static DHCP. It's as secure as self-assigned IP addresses, and it's easier to maintain when it's all in one central place.
Adjust signal strength to bare minimum needed
This will work on most days, but what happens when you get some interference, maybe due to some bad weather? Then your network goes down. It's a good idea not to put on way more strength than you need, but putting down the bare minimum is NOT a good idea.
