The handy WRT54GX serves as an Internet-sharing router, a four-port 10/100 switch, and an SRX-enhanced Wireless-G access point all at once. Relative to standard 80 2.11g technology, a network using all SRX products can extend network reach up to three times as far and boost wireless network speed by up to eight times. (Actual throughput, speed, and range depend on a host of factors, from building materials to network traffic and distance from the router.)
The device is Wi-Fi-certified and backward compatible with 802.11b (Wireless-B), 802.11g (Wireless-G) and, of course, other Linksys SRX products. Mixed wireless environments such as networks containing SRX, Wireless-B, and Wireless-G products can operate each client at its own maximum data rate. SRX products maintain their higher speed and range, providing the throughput and quality of service to deliver applications such as VoIP (Internet telephony) and video streaming.
SRX is based on MIMO (multiple-in, multiple-out) technology, a key component in the upcoming Wireless-N (802.11n) standard. To improve range and speed, MIMO uses two radios and three antennas on a wireless router or client adapter.
To enhance data protection and privacy, the router can encode all wireless trans missions with WPA (Wireless Protection Access). Its powerful Stateful Packet Inspection (SPI) firewall enhances protection to all the wired and wireless PCs against intruders and most known Internet attacks while also supporting VPN passthrough. Configuration is easy using a Web-browser-based configuration utility.
What's in the Box
Wireless-G broadband router, a setup CD-ROM with Symantec Internet Security, a u ser's guide on CD-ROM, an AC power adapter, an Ethernet network cable, a quick-i nstallation guide, and a registration card.

The new Wireless-G notebook adapter (PC Card adapter) from Linksys has both the 802.11b and newer 802.11g standards built in, so you can connect your notebook to existing 802.11b infrastructure and also the new, fast Wireless-G networks. The included setup wizard walks you through configuring the adapter to your network's settings, step by step. Then just slide the adapter into your notebook's PC Card slot and enjoy network access with your notebook computer, while retaining true mobility.
Wireless-G is the 54 Mbps wireless networking standard that's almost five times faster than the widely deployed Wireless-B (802.11b) products that are found in homes, businesses, and public wireless hotspots around the country. But since they share the same 2.4 GHz radio band, Wireless-G devices also work with existing 11 Mbps Wireless-B equipment.
Once you're connected, you can keep in touch with your e-mail, access the Internet, and share files and other resources such as printers and network storage with other computers on the network, wherever you wander. At home, you can surf the Web or use instant messaging to chat with friends while sitting out on the patio.
You'll also be able to connect to any of the growing number of public wireless hotspots springing up in coffee shops, airport lounges, hotels, and convention centers. And as those hotspots upgrade to the new high-speed Wireless-G standard, you'll be ready to take advantage of the increased speeds.
Get connected to current standard 802.11b networks today, and be prepared for the future with the Wireless-G notebook adapter from Linksys.

This is first narrative from two part series finding at the seemingly easy task of setting up Internet connection to protection Dvr. While this narrative will focus on general steps involved in proper connection forwarding to Cctv Dvr, the part two is all about dynamic Dns retain and workarounds. Before we step into the main subject, I like to elucidate very briefly a few key aspects of Internet connection for those of us not customary with term like Ip address, Ddns, port forwarding or Ip mapping.
Terminology:
Every computer or other network device, in our case Cctv recorder has its own address called Ip address, much like your home address it allows the facts to find its way in mountainous world of internet. Ip address has four groups of numbers separated by dots; the number range is between 0 and 255. There are two isolate networks that we need to take into consideration, Lan for Local Area Network and Wan for Wide Area Network. Lan has its own Ip addresses and handles connection on local network devices (computers or devices placed in your home or office network), if Wan Ip is your home address than Lan Ip would be your apartment number.
The Linksys Wireless-G PCI card connects you with Wireless-G networks at an incredible 54 Mbps. And for added versatility, it can interoperate with all the 11 Mbps Wireless-B (802.11b) products found in homes, businesses, and public wireless hot spots around the country. And in either mode, your wireless communications are protected by up to 128-bit encryption, so your data stays secure.
Don't hassle with running cables through your house--get your desktop connected the easy way with the Linksys Wireless-G PCI card.

Wan Ip is an external address visible to every user on the Internet. We will elucidate rest of the terminology as we go along.
Setup:
The best way to elucidate and elucidate guard Dvr connection setup is to use an example. In our example, we will setup Dvr model Vdv-074 from Dvrexperts through Netopia Router/Modem combo currently used by At&T Dsl supplier with static Ip service, I will also use Linksys Wrt54G Router for Cable Dsl connection. protection Dvr recorder needs to be related to the Internet through Router and Modem, in some cases Router and Modem are all in one devices, for example Netopia Routers.
For standalone Modems please associate the Internet out to Wan port, on your Router. associate Cctv Dvr and computers to available ports on the Router as well. Your Router will need to be setup now to log in to the Internet assistance supplier and fabricate connection.
Netopia Router users:
Open up browser on your computer and type into the address bar your routers default Ip http://
192.168.1.254. User name and password window should appear; the default user name and password for Netopia Routers are admin for user and serial number of your Router for the password.
Select Configure followed by Quick start link, type your Internet assistance providers user name (email address) and your Isp password. Click submit and alert icon placed in upper right projection (I know it is strange), finally make your mind up save and restart. Your connection should be up in small or so, click home link to see your connection status.
Linksys Router users:
Open up browser on your computer and type into the address bar your routers default Ip [http://192.168.1.1]. User name and password window should appear; the default user name and password for Linksys routers are admin for user and admin for the password.
The home page of the router has Isp settings, type in your email address as a user name and Isp password for the password, make your mind up save or submit. The Router will restart after small or so, log in again and go to status page to see if your connection status is Up.
If everything is ok and your connection is Up, we can now trek, to fun part of the setup process
There is great number of separate protection Digital Video Recorders on the market, so please ensue your Dvr's manual for details; I will only furnish the proper settings. In the Dvr menu, setup static Lan (Internal) Ip for the Dvr, in our example we have 3 computers and Dvr. Each gismo has assigned Lan Ip address as follows:
Computer 1 - 192.168.1.100
Computer 2 - 192.168.1.101
Computer 3 - 192.168.1.102
Dvr - 192.168.1.103
The guard Dvr will now be accessible within our network by typing its assigned internal Ip (192.168.1.103) into browser or connection software. What we need now is to transmit the connection from external Ip (Wan) which is accessible from surface of our network to the Lan Ip of the Dvr (192.168.1.103).
Netopia Router users:
Select Configure followed by advanced and finally Ip Maps. Ip map table should be empty, click on add and type into Ip Map Entry Name text box the name of your Dvr connection, in our example I just typed in Dvr so I know what this Ip map is for. In Internal Ip address box type in 192.168.1.103, for external Ip address refer to you Isp work sheet and find out what is your Ip. In some cases Isp will furnish more than one static Ip, you can select one of them.
Click submit and alert icon placed in upper right corner, finally make your mind up save and restart.
From now on anyone requesting external Ip will be forwarded to the internal Ip of the Dvr (192.168.1.103), therefore the connection should be established successfully.
Linksys Router users:
When setting up your Dvr for passage from the Internet, you will need to configure Port Forwarding on your Linksys Router. This can be done in one of two ways, definite Port Forwarding or the Dmz host. The Dmz host automatically forwards all incoming connection requests to a given Ip address on your local network. Open the Applications & Gaming section of the router and select Dmz. Dmz is not gather and should only be used with embedded, non-Pc based Cctv recorders.
To expose the Dvr to the Internet, enter the Dvr local Ip address (192.168.1.103) in the Dmz Host Ip address box. In some cases you may just want to transmit definite ports to your protection Dvr. If you are running any other device/server that hosts services available to the internet, you will want to use definite port forwarding instead of the Dmz Host, also if your Dvr is Pc based it is strongly recommended for protection reasons, to only transmit ports used by Dvr connection. Open the applications & Gaming section of the router and select Port Range Forwarding. Type in the name for the connection, starting port number, ending port number and internal Ip of the Dvr (192.168.1.103 in our example). Save and exit.
Your connection is now setup properly.
You probably noticed the term static Ip in this article, and are wondering what that is.
Well, static Ip is what the name suggests an Ip that never changes. While there is no qoute with internal Ip selection; we can use anyone we want or prefer - the external Ip, usually is dynamic. The static Ip has to be requested from the Isp and is more expensive than dynamic Ip. In our case we do want static Ip so we have address for Cctv Dvr connection that will never change.
Throughout this tutorial I have assumed that the external static Ip is available.
Unfortunately in many areas it is not, or the cost is prohibitive. Don't panic yet, there is at least consolidate of separate ways around this qoute and I will try to go over each arrival in my next narrative "How to use free dynamic Dns services for Dvr connection."
