  •   Wireless connections up to 300 Mbps*
  •   MovieEngine QoS feature to prioritize streaming traffic
  •   Built-in AirShare Storage USB 2.0 Port
  •   BitTorrent client
  •   Web Access remote Access
  •   Greater coverage compared to standard 802.11g

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.

Improve VOIP traffic in WRT54G

WRT54G Router,
DD-WRT 24 Sp1 firmware.
To improve VOIP traffic in the network, I put VOIP adapter mac address into the QoS features.
* Under ‘MAC Priority’, enter the MAC Address of the device
* Click ‘add’
* click ‘Save changes’
I put my SPA-2002 VOIP adapter at Premium priority.
After one week using, I fell the VOIP telephone/ conversion has better quality without jiggly.

Got a Linksys WRT54G router

I have a D-Link WBR1310. After two months usage, I found it is not suitable for my network environment.
The features are so limited. I need a powerful router will tons of advanced settings.
OK. I bought a Linksys WRT54G router last week. It is a discontinued product. I got one from the Office Depot, Vancouver Store.
Just because it is a discontinued product, it is only $40.

It is v8 edition.
CPU 240 MHz, Memory 8 MB, Flash memory 2 MB
Broadcom BCM5354KFBG Chipset with non-replaceable antennas.
I upgrade this device to the latest Linksys official firmware. Then I installed DD-WRT firmware to make it better.

DD-WRT Emule setting to improve performance

To get better performance and let other Internet activities work, I set my router’s DD-WRT as below:
Change IP Filter Setting,
Max Ports 4096
TCP Timeout 120
UDP Timeout 120
The smaller timeout will drop in-active connection faster.
Emule is one kind of P2P software. All P2P needs a lot of connections anytime.
If “ip-conntrack” table in router is full, the router will hang.
So give big Max Ports to allow more connections.
Any other P2P software can use this settings to improve performance. Including eDonkey, BT, etc.

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.

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.

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”.
