Protect wireless network without Encryption

There are six steps to secure the wireless netword. I feel it is too complicated for me at home.
I don’t want to remember the Password or WEP key.
So I choose the step 4 to protect my Home wireless network.
It is Enable MAC filtering
Allowing wireless connection only to known MAC address. MAC (Media Access Control) address is an unique identifier attached to most network adapters.
I wrote down all nic mac addresses. Including desktops, by command ipconfig/all, XBOX, DS lite, Sipura SPA voip adaptor, Wii, by look at the back of the box.
Encryption does slow down the transfer speed. Even the CPU overload on the router.

Upgraded to MovableType 4.23

It is a mandatory security upgrade. There is no MT4.22 for some unknown reason. So I upgraded my MovableType 4.21 to 4.23.
change logs here.
* Release Type: Security Release. This update fixes a potential vulnerability which has not yet been exploited in the wild.
* Mandatory? Yes, this is a mandatory security upgrade.
* Performance Implications: None.
* Plugins Affected: None. Your current plugins should continue to work as expected.
* Templates Affected: An update to the profile view template is required for those customers who use the community template sets and user profile feature.
* System Requirements: This release has no new or additional system requirements.
* Licensing considerations: None. MT 4.23 is a free update for users of any version of MT 4.x.
* Upgrade Fatigue: No further mandatory updates are planned for Movable Type in 2008.
If you use MovableType also, don’t wait, upgrade it now.

How to progect your WiFi

Let’s discuss the most important eight steps to protect your WiFi connection.
1) Don’t use default SSID
2) Change the SSID to something that does not identity your business or location.
3) Use a boring name for SSID, something like network5 or ntdile09ldk.
4) Change access point’s default IP and admin password.
5) Use WPA rather than WEP.
6) Change encryption key often, once or twice every month.
7) Restrict network connections to network clients with specified MAC addresses.
8) Do not broadcast your SSID.
And the last not the least step is to use wired connection if possible.

6 Steps to Secure Your Home Wireless Network

I use D-Link WBR-1310 as a sample to show you the 6 steps to protect your home wireless network.
1. Enable Encryption
* WEP (Wired Equivalent Protection) 64-bit and 128-bit: WEP is an old wireless encryption standard. Never use WEP encryption, which can be hacked within seconds.
* WPA (Wi-Fi Protected Access): WPA-PSK is also refered as WPA-Personal. This is a new version of wireless encryption standard and more secure than WEP. Most of the wireless adapters on your laptop will support WPA.
* WPA2: This is the latest wireless encryption standard that provides the best encryption. Always use WPA2, if both your wireless router and laptop wireless adapter supports it.
SETUP > WIRELESS SETTINGS >, WEP part. It has WPA2 too.

2. Change the SSID name
SSID (Service Set Identifier) refers to the name of your wireless connection, that you see on the “Available Wireless Connections” list from your laptop while connecting.
SETUP > WIRELESS SETTINGS >, Wireless Network Settings part.
ssid-settings

3. Disable SSID broadcast
You can avoid your wireless name from getting displayed on “Available Wireless Connections” on all your neighbors laptop.
Check the picture above. You can choose the “Enable Hidden Wireless”.
