When you build a wireless network in home to share your Cable or DSL broadband Internet connection, you need a wireless router and connected to the existing Cable or DSL modem. You can only create Wi-Fi network and share the broadband internet only if the Cable or ADSL services are available in your area. What if you have problem with the availability of Cable or DSL broadband services in your area? You still can create Wi-Fi network to share the Internet with your colleagues only if you can access the cellular or 3g network in that area.

Creating the Wi-Fi network with the availability of the 3g network, you need a special 3g router which supports the 3g modem such as DIR-450/451 D Link. You cannot use this router to create Wi-Fi network based on DSL/Cable services, its different router. On the hand, you cannot use Cable or DSL router to create Wi-Fi network based on 3g network. They are different routers, even though they can be used to create the same Wi-Fi network, but each has different input port.

Cellular routers need 3g/4g modem to receive the cellular network from the nearest 3g base tower via the air and extend it wirelessly for others to share the internet access. While Cable or DSL routers need the WAN input from Cable or DSL modem which receives the internet access using wired connection (local loop) to the nearest central office of the ISP. You are stuck with the wired to create Wi-Fi internet network. With 3g routers, you can create Wi-Fi network with the absent of DSL or Cable services, anywhere, anytime as long as you can access the 3g network in the area.

The question is: is there a single router device that can be used to create Wi-Fi Internet network or hotspots based on both 3g network and Cable or DSL services? Yes, Netgear MEBR3500 Mobile Broadband Router with 802.11n, GE LAN and GE WAN.

Ten years ago it was common for houses to have machine connected directly to the internet via a dial-up modem, whereas nowdays it would be very rare to find a house that doesn't have an existing network. Applications range from wireless Internet on a laptop, file sharing between two machines, a hard drive set up to distribute media around the home, a wireless printer which all the family can access or a games console piggybacking the main Internet connection.

The conventional methods of deploying a network around your home are well known; you can either connect via a network cable or connect wirelessly over the airwaves and while usually suitable, both methods have potential disadvantages. A newtork is limited because the devices have to have a physical connection. A wireless network is also limited as not all houses are able to have a good wireless network; a particularly large house or one with particularly thick walls for example.

Few people are aware that you are actually able to hijack your homes existing electrical circuit to network your devices together. Although not the ideal solution for many, it does have some quite distinct advantages if you find that a conventional wired or wireless network lets you down. All you need is a minimum of 2 power line access points which are plugged into normal plug sockets. The technology works by modulating a carrier wave along the existing power cables in your home therefore your entire home wiring essentially becomes a network cable that can be tapped in to at will.

Because you are using the existing electric cabling in the house, AC networking makes the distance between two points irrelevant. Plug your broadband router in to an power line adaptor downstairs and your computer in to one upstairs and with the minimum of fuss you'll have a physical connection between the two.

You can restrict access to the network by implementing a number of security procedures similar to those present on a wireless network but owing to the fact your neighbours will be on a different wiring ring, these features are potentially redundant.

What makes the technology more useful is that you can combine elements of power line, wireless and conventional wired networking together in the one location by building on the strengths of all three technologies. You could for example have a wireless router plugged in to both your broadband connection and a power line adaptor with a second router plugged in to a power line adaptor upstairs; You could also have two wireless routers at each power line point which would mean that the chances of being without wireless signal around the home would be slim.

Alternatively, have the wireless router plugged in to both your broadband connection and a power line adaptor downstairs but upstairs plug a power line adaptor straight in to a conventional wired network switch in a kids game room upstairs. They could then connect a PlayStation 3, Xbox and PC directly in to this switch therefore benefiting from a physical connection straight in to the router downstairs without having to worry about issues such as wireless signal strength.

Most modern day power line adaptors support 200Mbps which compares favourably to a standard wired network which would run at 100Mbps and a standard 'g' rated wireless network running at 54Mbps. Prices start at around £60 for a pair of power line access points.

• Two router on the same network can simply hybrid network setups – in case you have wired home network and want to connect some new Wi-Fi devices to it, installing a wireless router as the second router allows those devices to connect while allowing the rest of the network to remain on Ethernet.
• Wireless range and reach - adding a second wireless router to you Wi-Fi network can extend the reach of your network to accommodate far away devices.
• Network isolation - If you use the network connection between certain computers then installing those computers to use one router, isolates the network traffic from affecting the other router.

It is always better than connecting the second router with the Internet port?

This helps in separating two networks and allows certain traffic to cross. Sometimes this is necessary in a network setup but for most home networks.

In an way gateway mode the second router does network address translation, which means that computers which are connected to the second router can connect to computers connected to the first router.

1. You can set up a wired network in a single room using pre-packaged Ethernet cables.
2. You can also purchase bulk cable and connectors and run the Ethernet cables from room to room.

Or else you can hire a professional person / or approach a company like L&C Sunshine Technology to wire your home with in-wall Ethernet cable.

• Once your wired network is in place, it is now easy to add a wireless access point to allow wireless networking as well.
• The best way is to determine where the router will be located. Ideally, it can be close to you computer or to your broadband connection and to the peripheral devices where you wish to connect to the network.
• The next step would be to measure how much cable you’ll need.  If your house is pre wired with Ethernet cable, then it goes without saying that you need not follow the below instructions. If you need to wire Ethernet cable then the Ethernet cables must be run from the router to each computer or device that you would like to connect to the wired network. The best way to run or wire a cable would be to hire a professional. This can avoid the room being messy or the house filled with wires.
• End of each Ethernet cable is a standard connector known as an RJ45 jack. This will look like telephone jacks, but slightly bigger. One should always get the right color of wire for your home. Also selecting the right terminal, or pin, of the jack is also important.
• The next step is the Installation of network cards. You will have to need to add these cards to any computers or peripherals.
• Now connect your devices using the Ethernet cables. Do this by plugging the connectors into the jacks.
• It is important to ensure that all computers; the router and the modem are plugged in and powered on. Now, on one of the computer and run the Network Setup Wizard by clicking on Start, in Control Panel then Network Setup Wizard. Set up the wizard by following the instructions and then follow the same to the other computers and restart computer.

Now, the network is now setup and the systems will be able to share files, folders, in a single net / internet connection.

The Concept Of Network Security

Network security is all about taking some initiatives to overcome the problem of viruses and other security threats. But, when you will delve more into the details, you will find that network security has different meanings for different business enterprises. For instance, some believe that network security is all about installing few antivirus programs and firewalls, whereas, others believe that these steps are not enough to stop intrusions so they go for more sophisticated options.

Since network security is not a one-time effort, you have to consult with a right network security UK Company to get a better solution. Just by getting in touch with a right network security UK Company you will become able to enjoy following advantages.

• With enhanced level of network security you will become able to entice more customers by letting them know that your site is absolutely safe to shop from.
• By ensuring right level of network security, you will be able to enjoy better reputation. A security breach can tarnish the reputation of your company and it is hard to regain the trust of people, especially if their sensitive information is being compromised.
• By using right type of network security tools, you can actually use different security functions. For instance, you can use a function which will lock out a person who may be using incorrect password for several times in few seconds. This is to ensure that no one becomes able to discover a password just by making some wild guesses.
• With little or no network security, a hacker can access your computer to surf the internet, send out spam, etc. A stronger network security will help you stay away from this problem.
• In case some parts of your network are affected, you can always use specific security tools to detect the intruder to take specific action against him. This can always save you from bigger troubles.

By going through these aforementioned points it also becomes quite evident that network security actually works in three aspects – logon restrictions, password restrictions and intruder detection.

So, the fact of the matter is that if you really don't want your company's reputation to take a turn for the worse, you must never overlook the importance of network security UK . Also, you must keep in mind that firewalls are not enough to keep intruders away from your network. You have to use some sophisticated options otherwise you will end up getting in hot water.
