How to Set Up a Wireless Network ?
Today i tell you how to set up a wireless network .
Because setting up a wireless network requires an understanding of the systems that will make up that network, using pc diagnostics on each system before you begin is smart. For example, do you know the specifications for each computer? While it's not overly difficult to manually inventory each computer, computer diagnostic software can do it for you automatically with just a click of a button. Once an inventory has been generated for each computer, you can then print your inventories out and quickly see potential problems.
For example, you might realize that some of the computers run Windows XP while others run Windows Vista, Windows 7, or even Macintosh. You may also notice that some computers have wireless network adapters while others do not. You may even discover that some of the older network adapters do not support the wireless standard that your new wireless network will be running on.
Armed with this knowledge, you can prepare for the network set up. You may need to run down to the computer shop and buy a few wireless adapters. You may want to upgrade the operating systems of a few of the PCs to ensure compatibility. By running computer repair software beforehand, you can make these decisions and adjustments before setting up the network.
Once you've run the diagnostic computer repair software and know what you're dealing with, you can then start planning the network design. You'll need a wireless network router and compatible wireless network adapters for each computer. The router physically connects to your broadband Internet connection, so place it near your cable modem or DSL outlet. Initially, you will need to connect a computer to the router using a cable in order to configure the network. This is temporary. Once the network is set up, you can untether the computer and work wirelessly from that point forward.
During the configuration process, you'll use Internet Explorer to access the router. Use the documentation that came with your router for the specific address and password. For example, if you have a Linksys router, you'll enter “http://192.168.1.1” into Internet Express's address bar and use the username of “admin” and the password of “admin” in order to access the router's configuration interface.
While the specific steps will vary, the process is similar. You'll need to give your wireless network a name in the SSID field, choose an encryption type and passphrase, and set an administrative password.
Once the basic configuration has been set up, the next step is to connect the computers to the network. Assuming the network adapters have been installed and are turned on, turn on each computer and connect each one to the network individually. Do this by going to Start > Connect To and then selecting the network from the list. You'll be prompted to enter the passphrase you specified earlier. That's it. Your network has been set up.
If any of the computers have problems connecting to the new wireless network, check to make sure that their network adapters are turned on and consider using computer diagnostics to rule out problems with the wireless network adapter.

How to Install a Power Supply ?
If a computer won't start or computer diagnostic software
indicates that the power supply is problematic, installing a new power
supply may be your only option. Fortunately, this is one of the easier
computer repair tasks to do. Plus, since the problem originates in the
power supply, data loss isn't likely. Similarly, if you are building a
new computer, you'll need to install all of its components including the
power supply. In either case, the steps are primarily the same with the
main difference being the removal of the old power supply in an
existing system.
If you've previously computer hardware diagnostics tools to inventory your system and have a printout handy, take that along to the computer repair store so that you can select the right power supply for your system. If you don't have a printout, the computer technician should be able to help you select a compatible component.
Because you'll be dealing with an electrical component, following all safety precautions is necessary. Make sure that the computer is completely unplugged from its power source. If you're working on an existing system, your original power supply could retain a charge even if it's not plugged in, so treat it with care.
After disconnecting the power, remove all jewelry and gather your tools. Unscrew the screws holding the case together and carefully remove the case. Place the screws in a safe location. Find the existing power supply and unbolt it as well as disconnect the cables attached to the motherboard and other devices. Slide the power supply out of the unit.
To install the new power supply, you'll want to first look at the back of the power supply unit to make sure its voltage switch is in the correct position for your country. Once the voltage switch is confirmed to be in the correct position, slide the unit into position and attach the cables to the motherboard and other devices such as CD-ROM drives. If you overlook an internal device, it won't have power and will not run, so make sure to pay close attention to all of the devices inside your system. Once all of the power connections have been made, align the unit in the mounting bracket so that you can bolt it into place.
Reassemble the computer case, plug in the system, and power on your computer. You can test individual components to make sure that they're receiving power or you can use computer diagnostic software to run a quick system-wide hardware test. If the system passes all of the computer hardware diagnostics tests, then your installation is complete. While it's not necessary to use computer diagnostic software as a final step, it's useful for making sure that your installation was a complete success.
