mikrotik sells wireless products and routers

Mikrotīkls Ltd., known internationally as MikroTik, is a Latvian manufacturer of computer networking equipment. It sells wireless products and routers. The company was founded in 1995, with the intent to sell in the emerging wireless technology market. As of 2014, the company has more than 100 employees.[1] The company's products are known for being low-priced alternatives to expensive routers and Ethernet radio relay lines.
The main product of MikroTik is an operating system based on the Linux kernel, known as the MikroTik RouterOS. Installed on the company's proprietary hardware (RouterBOARD series), or on standard x86-based computers, it turns a computer into a network router and implements various additional features, such as firewalling, virtual private network (VPN) service and client, bandwidth shaping and quality of service, wireless access point functions and other commonly used features when interconnecting networks. The system is also able to serve as a captive-portal-based hotspot system.

The operating system is licensed in increasing service levels, each releasing more of the available RouterOS features. A MS Windows application called Winbox provides a graphical user interface for the RouterOS configuration and monitoring, but RouterOS also allows access via FTP, telnet, and secure shell (SSH). An application programming interface is available for direct access from applications for management and monitoring.

Mikrotik Routerboard RB750 5xPORT LAN ROUTER NEW IN BOX DESCRIPTION: An entirely new class of product in the RouterBOARD lineup, the RB750 is a small five port ethernet router in a nice plastic case. Not only is this an attractive looking tiny SOHO unit, it's price is lower than the RouterOS license alone - there simply is no choice when it comes to managing your wired home network, the RB750 has it all. Not only it's affordable, small, good looking and easy to use - It's probably the most affordable MPLS capable router on the market! No more compromise between price and features - RB750 has both. With it's compact design and clean looks, it will fit perfectly into any SOHO environment. Box contains: RB750, plastic case, power supply
Price:     $39.91 + $5.99 shipping

How to Set Up a Simple Wireless Network that support internet connection

 I will show you how to set up a Simple wireless router that support internet connection




You need to prepare :
1. A Laptop / PC have built in Wireless Support or attach with A PCI or USB wireless adapter
2. A wireless router
3. Internet Connection from internet service provider,

If you are building your first home network or you are re-building your home network you very well might want to go all-wireless. You'll need to make sure that all your computers and network devices either have built in wireless support or you may have to install wireless cards. A PCI or USB wireless adapter connects your machines to your network, often making access as easy as plugging the device in to a USB slot. Older machines can get an instant upgrade to wireless N with a USB WiFi adapter, or you can install a PCI wireless card into your self-built system. PCI & USB wireless adapters are also great as a backup in case a wireless card stops working, ensuring your laptops or other machines can still access the network. A PCI or USB wireless adapter have varition price from $4 to $100 depend on the quality.
With Wireless network it's easy to built Local Area Network (LAN) to connect some PC or Laptop and printer in your home / small office.


Where to Install a Wireless Router
Computers that are closer to the router, in the same room for example, receive better network speed than computers located farther away. So, Try to install your wireless router in a central location within your home or office.

Connect the Wireless Router to the Internet
First, connect the wireless router to a power outlet and to a source of Internet connectivity. You may be connecting your wireless router to a cable modem. All wireless routers support broadband modems, and some support phone line connections to dial-up Internet service.

One easy way to know if your router is wireless is if you see an antenna. This is a standard router that is not wireless. You can connect hubs, other routers, and switches to a wireless router. Keep in mind that although a hub is a small and inexpensive network device, switches provide better automated control of your network.
Access the Wireless Router
Once your router is on and plugged into your internet connection you'll need to access it. Go to a Web browser and follow the instructions that came with the router to connect to it. You'll likely type in 192.168.1.1. Your documentation should have the username and password necessary to access this information. The default username and password may be admin for both.
Create a Name for the Wireless Network
You should create a unique network name. This name is often called the SSID. Your router and all computers on the network must share the same SSID. Although your router comes with a default name such as Linksys or Netgear, it's best to change it. You don't want someone next door to have access to your network. Make sure your network is password protected; otherwise, someone can come along and slow down your connection.
Set Wireless Network Preferences
Lastly, follow the router documentation to enable WEP security, turn on firewall features, and set any other recommended parameters. If you do not know what something is, and don't have any documentation telling you to change it, I recommend just leaving everything as is

If you just make a Local Area Network (LAN) to connect some PC or Laptop and printer in your home / small office you do not need an internet connection.
