System Restore Wizard

Using the System Restore Wizard

The System Restore Wizard guides you through the steps of each task in System Restore.
When you run the wizard to restore your computer to an earlier state, it displays the following screens:
  • Welcome to System Restore
This screen gives you the option to restore your computer to an earlier time or state.
  • Select a Restore Point
This screen allows you to pick a date on the calendar and then select a restore point to restore your computer to an earlier state.
  • Confirm Restore Point selection
This screen allows you to change your mind about the selected restore point or the restoration and to save all files and close all programs before starting the restoration. After you confirm the selection, the restoration process starts, the system restarts, and a user logon screen is displayed.
  • Restoration Complete
This screen indicates your restoration has been successful. If the restoration fails, the Restoration was unsuccessful screen is displayed, and no changes are made to your computer.
For more information about System Restore, see System Restore overview.

Disable Wireless Router

You can disable a wireless router SSID broadcast and then connect to the router manually to improve security. This isn’t really necessary if you have WPA-2 enabled and have a secure password, but some people might prefer to have their router in stealth mode. When neighbors or strangers driving around down your street browse for a wireless connection, you might not want anyone to “see” your router. So, disable SSID broadcast and then set up a manual connection in Windows 7.

Disable The SSID Broadcast In The Router

Step one is to log in to the router and turn off the disable SSID broadcast. D-link, Linksys, Netgear and other routers handle this process differently, but you should find the SSID broadcast option in the Wireless settings of the router’s configuration.
disable wireless router ssid
Log in to the router and set the SSID broadcast to Disable.
connect to router with no SSID
In Windows 7,  go to Start -> Control Panel -> Network and Internet -> Network and Sharing Center. Then click on the “Connect to a network”  option.
connect to router with no SSID
Next, click “Manually connect to a wireless network.”
connect to router with no SSID
Lastly, fill in the details about your router. While you disabled the broadcast, the router still has its SSID–it just isn’t announcing it to the entire world.  Type the SSID in under “Network name.” Select the security type (WEP, WPA-2, etc) that your router uses. Then put in the password where it says “Security Key.”
You can choose the option to “Start this connection automatically” if you will be using this WiFi connection frequently.
Disable wireless router SSID to improve security, but keep in mind this can make connecting other devices, such as phones, tablets and gaming consoles a nightmare. Some devices may not let you manually input an SSID. If the device does not detect the your router SSID, it simply may not allow you to connect. So, depending on your need for wireless privacy, you may opt to either disable router SSID broadcast or simply give the router a name no one can associate with you and a strong WPA-2 password.

Blazing Fast External Hard Drive

How fast is fast enough when dealing with data transfer? When you’re dealing with backups or copying large files from one drive to another, you can never have too much speed. The new USB 3.0 spec emerged last year. The speed comparison between a USB 2.0 drive and a USB 3.0 drive is staggering. Fortunately, the costs have dropped and adding a USB 3.0 external hard drive to your computer has become an attractive idea.

USB 2.0 and USB 3.0 Speed Comparison

The leap in throughput was as substantial in USB 3.0 as it was between USB 1.0 and 2.0. With the newer USB 3.0 specification topping out near 5 Gbps, it is faster than the wired computer networks in most homes.
USB Speed Comparison chart
USB Speed Comparison chart
USB 1.0 speeds are 1.5 Mbps
USB 2.0 speeds are 480 Mbps
USB 3.0 speeds are 4800 Mbps

Investing In USB 3.0

Because the standard is relatively new, your computer may not have a USB 3.0 card installed. Motherboards will eventually ship with USB 3.0 on-board, but if your computer only has the older USB 2.0, then you’ll need to purchase a USB 3.0 card. The cable is also different. So there will be some investment costs in upgrading, but the price is minimal in comparison to the huge performance boost you’ll get after upgrading.

This USB 3.0 hard drive from Buffalo is said to out-perform internal hard drives. It is an external drive and would be great for moving massive amounts of data back and forth between computers or even just being used as a standard backup hard drive. It is backward compatible with USB 2.0, but you will want to invest in the USB 3.0 card to get the maximum performance. As with most external hard drives, this model also ships with its own cable, so you will not need to purchase the new USB 3.0 cable.

This Buffalo Technologies USB 3.0 card will enable your computer to get the full 4800 Mbps speeds out of your new USB 3.0 hard drive. You must have a PCI-Express port on your motherboard to install this, so make sure your motherboard has that expansion capability before purchasing. The card comes with a driver disk and is compatible with Windows XP, Windows Vista and Windows 7.

In Conclusion
As file sizes and hard drives get larger and larger, the time it takes to backup and copy data will increase. Having a USB 3.0 hard drive in your computer will eventually become a necessity. If you deal with a lot of files, or are into movie and photo editing, upgrading to a faster hard drive is paramount in maintaining a productive work environment.

Creating a First Aid kit to Your PC


For many computer users, troubleshooting individual issues can be very time consuming and wasteful. If you value your time, you need to have a plan in place that will fix bugs quickly and efficiently.
The simplest way to accomplish this would be to create a fast “full reset” process for your system. The moment your computer starts to show signs of trouble, you can just wipe it clean instead of spending hours trying to fix malware, viruses or other obscure bugs.
This post is intended for people who’ve either:
  • just bought a new computer,
  • or who have just recovered from a major crash.
In order to do this properly, you’ll need to set up 2 different tools:
A fresh, fully-functional system image
The first thing that you’ll want to do is set up a fresh copy of Windows, with all of the latest updates. Next, you’ll want to install all of the programs that you might need. This may in include Firefox, MS Office, Adobe Suite, or any other applications you’ll use on a daily basis.
Once you’ve installed all of your applications, you’ll want to create a snapshot or “system image”. Backing up a system snapshot with pre-installed applications will allow you quickly reset your computer in one easy step, without having to spend hours manually loading these programs again.
Next, you’ll need to make several copies of this system state image. Keep one on-site, and one off-site.
This can be as simple as burning 2 DVDs and mailing one to a friend. Or, you can also try keeping one copy backed up with an online storage provider for easy download… or on another computer via FTP.*
A recent and up-to-date file backup
Of course, a good system image is just a time-saving tool. It isn’t enough to keep you protected. For that, you’ll need an automated backup process.
Automated backups are especially important because manual backups just don’t cut it. Just like starting a diet, backing up data is a habit that gets neglected and eventually dropped over time.
Another disadvantage of manual backups is that they leave a large “data-loss window”. Most home users will back up once per week or once per month. This leaves 7 to 30 days worth of your most important data at risk at all times. (Your most recent files are usually the most critical)
Compare this to an automated backup system that can copy files over every few minutes… and never forgets. It’s almost impossible to lose any data with these types of applications.
An off-site NAS box is good for remote backups. But the best solution would be an online backup service, since it’s much more resilient, secure and maintenance-free.
Once you’ve got a good system image and backup process in place, you now have a fast and convenient solution for 90% of your computer problems. If you start to notice your machine acting strangely, just reinstall your system image, then download your latest file backups on top of it.
This will help ensure that your machine is always fresh, clean and running smoothly.
* I’d strongly advise against storing any backup data with your web host, since it may be against their “Terms of Service”. Violating this agreement could get your web site shut down without notice.

Wired Network Set Up

A wireless network is convenient.  But in terms of speed, reliability and security, a wired network is the way to go. You can wire your entire home over a weekend and we’re going to give you some pointers on how to do this. When you’re finished, each computer in your house will have a Gigabit connection with blazing fast Internet and file-sharing capabilities.
What you’ll need for your wired network setup:

ethernet cable kit to wire a home network
PTC Premium 1000 ft Category 5e (Cat5e) Blue Ethernet Cable Kit with tester, crimper and connectors
WOOD SPADE BIT 1-1/2
Drywall Saw
50′ Electrician’s Fish Tape
Drill
Twine Heavy Duty
Cat 5e 8-Wire QuickPort Adaptor Jack (and wall plate)
Intel PWLA8391GT PRO/1000 GT PCI Network Adapter
D-Link DIR-655 Extreme N Gigabit Wireless Router
You might already have a Gigabit router and a Gigabit network card. Check your system specifications before buying them. The router above is only a recommendation. You can use any Gigabit router, but we recommend sticking with D-link routers or Linksys routers. The wired network router should have at least four LAN ports on the back.

Ethernet Network Setup

Of course, everyone’s network setup will be different. They theory is this: You have an Internet service coming into your home through a basement and you want to wire the house with Ethernet cabling.
wired router
The best way to do this is to situate your router in the basement near where you want to run your leads.
network wiring
Locate an electrical cable for an outlet on the first floor. This tells you where the wall upstairs. If you do not do this, you risk drilling through the floor and carpeting upstairs.
Once you locate the electrical cable, measure over several inches and drill your hole.
Next, go upstairs to the wall where you drilled your hole. You should see the electric outlet from the electrical cable you noticed in the basement. Using a step ladder and the drywall saw, carefully cut a 6 x 6 inch square hole in the wall near the ceiling (just large enough to fit your hand in). Cut the hole as clean as possible, as you will need to use the piece you remove to patch the wall afterward. You should see the 2 x 4 wall stud and the ceiling joists running across it.
You will now need to go to the second story and locate the wall directly above where you made the ceiling cutout. You will then need to cut a larger square to accommodate the drill. The idea is to go through the floorboards, miss the ceiling joist and then drill down through the stud of the wall where you made your smaller cut.
wired network
Then, go into the attic directly above the space where you made the larger cutout on the second floor. You can use the same method you used in the basement if the second floor room wall happens to have an electrical outlet. The electrical wires are likely run through the attic and down into the wall. Drill through the attic floor and then insert the electrical fish lead into the hole. You should be able to grab the fish in the hole you made in the second floor wall. Insert the fish into the hole you drilled in the floor and then pull it through on the first floor.
Tie and tape the twine to the hook on the end of the fish and return to the attic. It’s best if someone can hold the twine on the first floor so it doesn’t get tangled. Pull the twine up through the attic floor. Pull through several extra feet and tie it off on one of the trusses on the ceiling.
In the basement, work the fish upward, then return to the first floor and pull it through the opening where the twine is going up to the attic. Give yourself about ten feet of slack and then cut the twine. Tie and tape it to the fish and then return to the basement and pull it through the floor. You now have a single piece of heavy-duty twine leading from the basement all the way up to the attic.
Next, take some measurements and figure out how much Ethernet cable you’ll need to go up to the attic and then down into the rooms on the second level. Once you have the measurements, add an additional twenty feet ( it’s better to have extra cable than not enough). You should be able to run all of the lines up together if the hole you drilled is large enough for the wires to fit through easily (you do not wan to bend or crimp the network cables). If the holes are not large enough, run the network cables up one at a time. The trick to this part is to tape another piece of twine to the wired network cable going up so, when pulled through, you still have a piece of twine leading from the basement to the attic.
Tip: Even if you can fit all of the Ethernet cables through at the same time, you should still run the twine up to the attic and tie it off for future network setup use. You only want to cut holes in your wall once.

Once you have all of the network cables run, you can make the connections to the router and then to the wall jacks in the second floor rooms.

Integrating Wifi Into Your Network

You will still want to have a wireless network setup for portable devices such a smart phones and laptops. The router’s signal installed in your basement will not likely reach the second floor. You can install an old wireless router that has been converted into a Wireless Access Point on the second floor. Read more about converting a router to a wireless access point here. Or you can buy a Wireless Access Point (WAP)and install it upstairs. The WAP will plug into your wired network and provide WiFi for those areas of the home not covered by the router in the basement.
If you have questions about a network setup, contact us on our forums. Everyone’s network setup will be different, but wiring your home for Ethernet will provide you with a faster, safer network.

How to Set Up An Ad Hoc Network

Most people will have their wireless devices and computers setup for Infrastructure networking, meaning the network is handled by a router. If you are in a situation where you need to transfer files and data from one wireless computer to another, you can quickly setup an ad hoc network, however.  An ad hoc network is considered computer to computer networking without a router  or access point present.  One such application of this type of networking would be a business meeting environment, where you need to quickly transfer files to an associate. Simply setup an ad hoc network on your computer and then have the client search for and connect to the shared folder on your PC.

Configure An Ad Hoc Network

One computer will create the network and act as the host. The other computers will then search for and connect to the computer. Once the host computer is shut down or out of wireless range, the network is gone.
Setup the connection by going into the Control Panel and clicking on the Network Connections icon. Identify your wireless connection. Right-click the connection and then select Properties.
Click on the tab that says Wireless Networks.
setup an ad hoc network
In the Preferred Networks section, click the Add button.
Under the Association tab you will first give the network a name or what is called a Service Set Identifier (SSID). This is the name people will see when they look for available networks.
Set the Network Authentication as Open and then configure the encryption as WEP or WPA-2 (WEP is more compatible with older wireless adapters but considered weak encryption). Setup a password, then un-check This key is provided by me automatically. You will then check the box that says This is a computer to computer (ad hoc) network.
Note: It is imperative to setup a complicated password or strangers will be able to connect to your computer in public. Or when the ad hoc network is no longer needed, just delete it for security purposes.
Click OK to save your changes. Your network will now show up under the Preferred Networks section.
At this point, the host computer can then setup a shared folder. You can create a folder anywhere by right-clicking an open area and selecting New Folder. Name the folder anything you want and then right-click and select Sharing. Give the folder a name, and place any data you want to share into that folder. Newer versions of Windows will also have a Public folder, which is an open folder other computers can see an access once they connect.
Allow Other People To Connect To Your Computer
Now that you have created an ad hoc network, people can browse for your network and connect to you. To do this, locate the wireless icon in the system tray and then right-click that icon.
view available wireless networks
Click View Available Networks. If the host computer is powered on and configured correctly, it will be displayed as an available network. They will then need to type in the password to establish a connection.
