How to Buy the Best Network Hardware and Set up By Yourself?

Generally speaking, computer hardware means knowledge of assembling different computer parte together for the proper functioning of a computer. Networking means linking the networks of various companies on a common platform so that the requisite data can be shared easily by the companies. Therefore, knowing the basic knowledge of choosing or buying network hardware is vital. But we all understand that it’s easier to say than to do. Now, we collected some materials after a long time of hard working aim to help those who are confused on buying the right network hardware.
1. Balancing network costs and performance
It’s no doubt that Speed, collaboration and connectivity reign supreme in the modern global economy. Thus, we should consider the quality of network hardware without doubt first, and Cisco-as the leading brand in this field, is the best choice certainly. But for some individuals, the related higher price may be a problem. Fortunately, there is a lot of Cisco refurbished network hardware to choose from at market, especially at online shops.
The most obvious reason is that a refurbished hardware typically sells for between 10 to 30% less than the equivalent brand new unit. Depending on the model, this can mean hundreds of dollars in savings. Besides, the refurbished hardware includes the same one-year limited warranty that comes with all new hardware. Therefore if the refurbished computer is not satisfactory, it can be returned without hassle. Meanwhile, Cisco pre-installs the operating software originally shipped with the hardware and it provides the strong technical support for all Cisco equipment no matter it's new or refurbished. However, there are also some disadvantages of refurbished hardware. For example, they are not subject to any customization. Memory, hard drive space or other upgrades must be purchased separately.
So, we advise the buyer choose the network hardware carefully according to your situations with the above tips.
2. Understanding the influence of your Internet connection
When planning your network infrastructure always consider how employees will share access, what type of records you would like to maintain, what type of flexibility your company demands such as wireless access and how you plan to incorporate peripherals.  Your network hardware and configuration are the key elements to driving employee collaboration and connectivity. While IT departments spend much of their time and budget on personal computer equipment, choosing your company's network hardware infrastructure is a critical business decision.
3. Selecting the proper wireless network components
The basic devices in a wireless network are: The Wired Network, Access Point or Wireless Router, Client Device, Client Bridge, and Repeater.  Each component has a specific function, and while some devices can operate in more than one function, they often have specific attributes that best suit them for a given function.

4. Setting up your Own Wireless Network
If you have known the importance of network hardware and bought one, the next step you must try is to set up your own wireless network. And this process is no longer difficult after you know how to connect the wireless router and configure it.

First, you need to locate your cable or DSL modem and unplug it. Next, you must connect your wireless router to your modem (modem must be stay directly connected to the Internet). Do this by plugging one end of a network cable into the modem and plug the other end to the Internet, WAN or WLAN port on the router. After hooking everything up, the computer will automatically connect wirelessly to the router, and the router will consequently send information through your modem to the Internet.
In terms of configuring the wireless router, you should use another network cable, temporarily connect your computer (through the network adapter) to one of the open network ports on your router (make sure the port is not labeled Internet, WAN or WLAN). When turned on, your computer will automatically connect to the router. Afterwards, open the Internet Explorer on your computer and type in the address in order to configure the router. The address (and password in some cases) varies depending on the brand of your router, so you would need to refer to the instruction manual.
