Is your computer running slower than ever? Does it crash a lot?

If so it might be because advertisers have loaded it up with Spy and Adaware without your knowledge.

“Spyware” is a common term for files that are installed on your system that allow companies to monitor your Internet activity.

“Adaware” is software that will show you pop up ads over and over. These files can be extremely dangerous to your PC and could cause major problems.

They track the websites you visit, items that you buy online, the emails you send and your Instant Message dialogues. In a worst case scenario they can even record your credit card number, personal identification numbers, and all of your passwords.

I know all of this because I learned the hard way. Fortunately, I never had any personal data stolen, at least that I’m aware of. But every now and then, when least expected, my computer would crash, sometimes resulting in days of lost activity and income.

It seems like I spent a small fortune fixing one problem after another. I bought expensive software programs that actually made my problems worse, then another hard drive that I really didn’t need.

Ultimately I had to take my computer to 2 different techs to work out all the bugs. If only I knew then what I know now.

After months of frustration and too many hundreds of dollars I care to admit to I finally learned what it takes to keep my computer healthy and functioning properly.

Below is what I learned and a recommendation that can help you avoid what I went through.

1. Get a spyware removal program. You’ve heard it before, but have you done it? This helps as your 1st line of defense against hackers and viruses.

2. Avoid opening email attachments from people you don’t know. When in doubt, don’t do it. Granted, this isn’t so easy to do when you’re in the people business, but I still encourage you to manage it as best you can. This alone eliminated a lot of my problems.

3. Scan for viruses and clean your registry at every opportunity. I spend a lot of time on the Internet working on my website marketing products, sending and receiving email and the like.

Consequently, my computer is vulnerable to attack from a lot of different ways. So, I scan it for viruses and clean my registry daily; sometimes several times a day depending on how long I’ve been on it.

If you don’t have a good spyware program you should get one. It’ll help you optimize your computer’s performance, and get it in tip top condition in no time.

Here are the benefits.

They’ll let you:

know if you have any files that are infecting your PC

help protect your computer and eliminate trojans, worms, dialers, browser hijackers, etc., and

help you avoid serious problems before they happen

You’ll be amazed at how much speed and problem free use you can regain from the use of your computer after you install a good spyware program.

If you don’t have one I strongly recommend Spyware Nuker. It’s relatively inexpensive and is money well spent to safeguard your computer and personal and professional information stored on it.

You even get to try if for free before you buy it and I believe it comes with a 90 day satisfaction or money back guarantee.

Happy listings and please feel free to call me if I can be of assistance.

The first installment in this two-part series of Tech Tips provided an introduction to the basic capabilities and hardware involved in wireless networking. In the final installment of this two-part series, we will look at some of the basic setup and security considerations that should be addressed. The physical installation of a wireless network may be easier than a wired network, but the more difficult part is setting up the software and security to make sure everything stays up and running without incident.

Although this Tech Tip is by no means an exhaustive resource on configuring a wireless network, it will provide information and pointers that can be applied to most typical installations. Many of these tips are general enough that they may provide some good advice for those utilizing wired networks as well.

For the sake of this article, we will assume that the hardware has been successfully installed physically, and that the user is now prepared to set up and secure the system through software. Wireless devices, especially routers / access points, generally include a web-based configuration utility that allows the user to customize the hardware to meet their needs. The hardware will most likely work with minimal configuration, but to make it work so that the integrity of the network is protected may take a few more steps.

In addition to the configuration interface provided with the wireless networking hardware, Microsoft has integrated a “Wireless Network Setup Wizard” with the release of Windows XP Service Pack 2 that will lead a user of any expertise through the installation of their network. In addition, the “Microsoft Broadband Network Utility” will help them monitor and maintain the network just as easily once it is set up.

Change Default Password

Routers, whether wired or wireless, require a password for configuring the various settings, and all of them ship with extremely simple default passwords. The first step taken in setting up the router should be to change the default password to something more difficult to guess. Longer passwords that use a combination of letters and numbers are preferable as they make hacking attempts that much more difficult.

Change Router IP Address

Most routers ship with a default IP (Internet Protocol) address, something like 192.168.1.1, which is utilized by the user for accessing the configuration utility interface, as well as by the network itself for negotiating the LAN and WAN connections. The configuration utility of most routers will include a page that will allow for the default IP address to be manually changed by the user. Although changing the default IP address doesn’t provide a great amount of security since it can easily be discovered anyway, it may deter intrusion by local users that may be casually scanning the network.

Configure Router or Access Point Use

In the first part of this series of Tech Tips, I mentioned that almost all routers intended for home use can also double as wireless access points, and this is generally accomplished by clicking a check box within the control panel software. If a wireless router is being added to a network with an existing router and broadband connection, the new device needs to be set to access point mode. Otherwise, there could be a conflict as the network may not know where to expect the internet connection, since it will now have two routers that both want to serve as the gateway. If the wireless router is replacing an existing router, or is the only one on the network, this should not be an issue as these devices generally ship configured to operate as a router by default.

Broadcasting the SSID

The SSID, or Service Set Identifier, is basically the name assigned to a particular wireless network. The user can choose just about any name they want, as long as it is less than 32 characters long, and they just need to be sure that all computers on the network are configured to use the same name. Two steps related to the SSID can be taken to help improve the security of the network:

First, change the default SSID to a unique name that includes a combination of letters and numbers that doesn’t reveal anything personal about you or your network. Second, disable the broadcast of the SSID once all of your computers are successfully connected, even if your router / access point recommends broadcasting it. I have used a few wireless routers, and all of them have a check box in the control panel for enabling/disabling the broadcast of the SSID, and they have all recommended leaving broadcasting enabled. Broadcasting the SSID allows new computers to easily find your network, and then all they have to do is access it given the proper credentials. Broadcasting your SSID puts it out there for anyone within range to see, and it just allows would-be hackers to get one step closer to compromising your security. In a home environment, there are probably few computers that need to access the network, and if more are ever added, you can temporarily enable the broadcast to get them set up.

DHCP Server

The DHCP (Dynamic Host Configuration Protocol) Server is a feature of most routers that makes adding new computers extremely simple. Whenever a new computer connects to the network, the router will assign an IP address to it, instead of the user having to assign an IP address to each manually while sitting at that particular computer. This makes configuring a network very easy, but it also leaves the network vulnerable, as any new computer detected will be welcomed to the neighborhood and assigned an IP address automatically. Two different approaches can be taken to improve security, as related to the DHCP server:

One method, and the best as far as security is concerned, is to disable the DHCP server. This will require that all computers that are authorized to connect to the network be configured manually, but it will prevent unauthorized computers from obtaining an IP address. The second method, which doesn’t provide bulletproof security, is better than doing nothing. In general, a DHCP server can support up to 250 computers, and by default leaves a range of addresses readily available for that many to connect. If disabling the DHCP server doesn’t seem convenient for a user, they can limit the DHCP server to only provide as many IP addresses as they know they need. If you know there will never be more than five computers connected, limit the range of available IP addresses to a total of five within the configuration utility.

Different Levels of Encryption

All wireless components support some sort of encryption, which simply scrambles the information being sent across the network so that it can not easily be read by anyone else connected to the network. There are different types and levels of encryption, and a brief overview is provided for them below:

WEP, or Wireless Equivalency Protocol, was the first format of encryption available on wireless networks. WEP allows the network administrator to assign an encryption string to be shared by all computers authorized to access the wireless network. The encryption through WEP is either 64bit, 128bit, or 256bit, where the higher number represents greater encryption, and the strings can be generated by the administrator as a series of letters and numbers.

WPA, or “Wi-Fi Protected Access,” is an improvement over WEP that starts off with a similar master encryption string and then mathematically derives encryption keys to keep the security dynamic. WPA continually changes the encryption keys used for each packet of data, and due to the extra processing required to support this protocol the overall throughput of the connection may suffer slightly. Despite the potential for decreased speed, WPA is considered to be far more robust than WEP, and should be implemented where possible. In some instances, WEP encryption has actually been defeated, making WPA all that more appealing.

Although most components support both of these encryption formats, and users can select the type they wish to use from within the control software, not all do. All devices on the network must be set to operate at the same level of encryption, which may mean that some devices will force others to be less secure than they are capable of. For example, a wireless network setup around this router (http://www.geeks.com/details.asp?invtid=DI-824VUP&cat=NET) could support either WEP or WPA encryption. When two computers are added to this network using one of these network adaptors (http://www.geeks.com/details.asp?invtid=WN-4054P&cat=NET) in one case, and one of these network adaptors (http://www.geeks.com/details.asp?invtid=PBW006-N&cat=NET) in the other case, things change. Note that the second adaptor does not support WPA; therefore the whole network must now be configured to use WEP to accommodate it.

Router Position

As discussed in the first part of this Tech Tip, wireless devices can have a range of up to a few hundred feet in free space. When installed inside a home, this range may decrease greatly due to walls, floors and other obstructions, but the signal may still be strong enough to carry beyond the confines of the dwelling. A simple step that may help reduce the strength and reach of the network signal outside the house is to position the router / access point as close to the center of the house as possible. The potential for someone to detect the network from outside the home when positioned like this is now much less than if the router was placed near a window, for example.

Final Words

There are definitely additional issues that could be considered when setting up a wireless network, but covering these basics will make a wireless network much more secure than it was straight out of the box. Many people are confident that no one would be interested in their home network and feel security is just one more headache of technical mumbo-jumbo that they would rather not deal with. Whether a hacker wants access to personal files on the network or to simply gain unauthorized access to the Internet, a few simple steps are worth the peace of mind to know you are as secure as possible.

You will never meet that 108mbps that most wireless routers are saying to have but to come close you will have to purchase a wireless adapter from the same manufacture.

Installing your wireless adapter

1. Stick your adapter into your PCIMICA slot on your laptop. Windows xp will automatically recognize the card and ask you for the driver. If you are skilled at installing drivers then I recommend finding the driver manually not by using the manufacturers’ software to install the driver.

If you use their disk installing program you will also install a bunch of other crap that you don’t need. It will install wireless scanning software and wireless monitors that will just bogg down your system.

2. Now that you have your driver installed you should be able to scan for wireless networks. In the bottom right hand taskbar you will see a computer symbol with radio waves coming out of it. This is apart of Microsoft’s zero config wireless utility. This feature is good and bad because it will try to connect to any wireless network in range and once you have connected to that network once it’s available it will always try to connect.

This is bad because if you connect to a network called “Linksys” you will be connecting to a unsecured network because this is the default SSID of alll Linksys wireless routers.

Connecting to wireless networks can be dangerous because they could be a hackers rogue access point meant to collect password info on you.

3. I assume you know which network you want to connect to so lets go to the your wireless adapters properties by clicking twice on the wireless icon in the task bar and clicking properties.

Click on the wireless networks tab and click add. Type in your SSID of you network. If this is your Home wireless network make sure you have changed your SSID to something obscure and change your wireless channel to something other than channel 6.

Next you need to choose the same type of encryption you have chosen for your wireless router or adater. Hopefully you have chosen WPA2-PSK with TKIP or AES encryption.

You might have to install the Microsoft update for WPA2 support for windows xp- click here

You will Know if you have to install the update because you will not see the option of WPA2.

Now enter you encryption key hit OK and you should be able to connect to your network.

Advance options

Go back to you wireless adapters properties and lets take a look at some advance options. Options will vary in name but not in general function.

1. You should be on the general tab of the wireless adpaters properties and click on the configure button next to the name of the wireless adapter.

2. Click on the advance tab, (warning some of these setting can cause you to drain your laptop battery a lot quicker but it will improve performance.

3. First change your channel to 11 or the same as your wireless network. The default channel for most wireless networks is 6.

4. You can change you MAC address if want

5. If you want to reduce your power output you can. This will most often be done for security reasons to maks client positions so hackers can’t attack them.

6. You will have some sort of powersave mode or performance standard to either save battery life or concentrate on the most performance

7. Roaming options of Maximizing Bandwidth or distance – If you are really close to an access point and are downloading music then you will want to maximize your band with. If you are not close to an access point then you will need to change it to distance.

These are just some of the advanced options for your wireless adapter. Many people don’t even know they are there.
