Cisco is the worldwide leader in networking for the Internet. Cisco provides the broadest line of solutions for transporting data, voice and video within buildings, across campuses, or around the world. Cisco solutions ensure that networks both public and private operate with maximum performance, security, and flexibility.

The more authentic information about Cisco Systems you know, the more likely people are to consider you a Cisco Systems expert. Read on for even more Cisco Systems facts that you can share.

Pros: Great ADSL router. Very reliable and flexible configuration. Great firewall features. Extra security extensions for this version may not be needed. Nice built-in managed switch but limited to 100mbs on the LAN.

Cons: A little complex for the average users. Really needs more than a basic understanding of networking to configure. GUI set-up tool (SDM) is not as good as using CLI but much simpler and does get the job done. Limited to 100 mbs on the LAN side.

Other Thoughts: If you understand networking and routers, and you're hooking up to ADSL, this is your router. Excellent performer in a home or small office environment with up to maybe 25 users and 15mbs. Never a reset. A better configuration than stock is to use a gigabit switch with one port to the LAN side of the router and the others to the LAN users. This will provide gigabit speeds to the LAN users and still have the full bandwidth to the router and the internet.

Now you can understand why there's a growing interest in Cisco Systems. When people start looking for more information about Cisco Systems, you'll be in a position to meet their needs.

The Cisco 870 Series Integrated Services Routers extend the high-performance Cisco Integrated Services Router capabilities of running secure concurrent services, including firewall, VPNs, and WLANs, at broadband speeds to small offices. Easy deployment and centralized management features enable the Cisco 870 Series to be deployed in small office or teleworker sites as part of an enterprise network, by small to medium business customers for secure WAN and WLAN connectivity, or used by service providers to offer business-class broadband and WLAN services.

Cisco 870 Series of integrated services routers are fixed-configuration routers that support multiple types of DSL technologies, broadband cable, and Metro Ethernet connections in small offices. They provide the performance needed to run concurrent services, including firewall, intrusion prevention, and encryption for VPNs; optional 802.11b/g for WLAN networking; and quality of service (QoS) features for optimizing voice and video applications. In addition, the Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and deployment, and centralized management capabilities give network managers visibility and control of the network configurations at the remote site.

So now you know a little bit about Cisco Systems. Even if you don't know everything, you've done something worthwhile: you've expanded your knowledge.

Linksys RangePlus Wireless Router WRT100 Wireless router - EN, Fast EN, IEEE 802.11b, IEEE 802.11g

This interesting article addresses some of the key issues regarding Linksys RangePlus Wireless Router WRT100 Wireless router. A careful reading of this material could make a big difference in how you think about Linksys RangePlus Wireless Router WRT100 Wireless router.

If you base what you do on inaccurate information, you might be unpleasantly surprised by the consequences. Make sure you get the whole Linksys RangePlus Wireless Router WRT100 Wireless router story from informed sources.

The RangePlus Wireless Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect to the network without wires. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection.

The Access Point built into the Router uses smart antenna technology to achieve extended range. Unlike ordinary wireless networking technologies that are confused by signal reflections, the "Multiple In, Multiple Out" (MIMO) technology actually uses these reflections to increase the range and reduce "dead spots" in the wireless coverage area. The robust signal travels farther, maintaining wireless connections much farther than standard Wireless-G.



With MIMO, the farther away you are, the more speed advantage you get. It works great with standard Wireless-G and -B equipment, but when both ends of the wireless link are MIMO enabled, the router can increase the throughput even more by using twice as much radio band. But unlike other speed-enhanced technologies, the RangePlus Wireless Router can dynamically enable this double-speed mode for compatible devices, while still connecting to other wireless devices at their respective fastest speeds. In congested areas, the "good neighbor" mode ensures that the Router checks for other wireless devices in the area before gobbling up the radio band.

To help protect your data and privacy, the Router can encode all wireless transmissions with industrial-strength 256-bit encryption. It can serve as your network's DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks, and supports VPN pass-through. Configuration is a snap with the web browser-based configuration utility.

With the Linksys RangePlus Wireless Router at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games, and run media-intensive applications at incredible speeds, without the hassle of stringing wires!

As your knowledge about Linksys RangePlus Wireless Router WRT100 Wireless router continues to grow, you will begin to see how Linksys RangePlus Wireless Router WRT100 Wireless router fits into the overall scheme of things. Knowing how something relates to the rest of the world is important too.

How To Do a network with router and switch Turning a Router Into a Switch For Networking

The following article presents the very latest information on network with router and switch. If you have a particular interest in network with router and switch, then this informative article is required reading.

I recently ran into an interesting situation while setting up a network for a client of mine. I'm sharing this problem and its solution in hopes that someone else facing the same scenario might find it useful. My client's network originated from a Comcast router that provided four LAN lines servicing two rooms in his office/warehouse. In the main office, I set up a computer that would act as a network server. The computer was connected to the office's printer and fax machine. We put the files that needed to be accessible to the rest of the employees (including those working in the other room) on this computer, and I attempted to hook everyone up to the network.

The office I was setting up uses Vonage for their phone lines. We had two Vonage devices daisy-chained from one of the Comcast cable outlets in the room. The Vonage router that was next in line from the Comcast LAN connection was a Motorola VT2442. Connected to the Motorola VT2442 was a D-Link VWR wireless router. Because most of the computers used in the office are laptops, I had no trouble setting up a network that would allow access from any computer hooked directly to either of the two Vonage routers. The problem came in to play when we realized we needed to connect a desktop in the next room to our network. By logging in to the two Vonage routers, I set them up on the same subnet (192.168.15.x). However, the isolated desktop in the next room was receiving an address from the Comcast router that was on a subnet 10.1.10.x.

After searching online for a resolution and finding nothing that worked, I called Vonage's technical support. Kudos to those guys. Here is what we figured out.

If you base what you do on inaccurate information, you might be unpleasantly surprised by the consequences. Make sure you get the whole network with router and switch story from informed sources.

Probably because I'm not an expert networking guru, I wasn't aware that you can change a router into a switch. That's what had to happen in this situation. Thankfully, the Vonage technical support guy walked me through the following process.

I unplugged the Comcast LAN connection from the WAN port on the Vonage Motorola device, and I plugged it into one of the LAN ports on the same device. I then took another Ethernet cable, and I plugged it into another LAN port on the Motorola device. I connected the other end into the WAN port on that device. Apparently, setting up a router in that configuration changes it into a switch.

I followed the same pattern on the Vonage D-Link VWR device, connecting one of the remaining LAN ports on the Motorola device to one of the free LAN ports on the D-Link device. After setting up these devices as described, I was able to set up a network based on the subnet being perpetuated by the Comcast router (10.1.10.x), and every computer in the office (including the renegade desktop in the other room) was able to connect to the resources they needed on our network server.

The moral of this story: If you find your subnets aren't catching, make some switches from your existing routers.

That's the latest from the network with router and switch authorities. Once you're familiar with these ideas, you'll be ready to move to the next level.
