Things to consider when buying a wireless routers for your small business.
We live and work in an untethered world, and your small business is no different. When you initially built your network, you may not have seen the need for wireless. Now that your company has grown and your workforce has become more mobile, you may be considering adding wireless to your network. Wireless offers a lot of benefits, such as  allowing your employees to work from anywhere and providing Internet access to visiting guests.
If you’ve been looking at adding wireless connectivity to your company’s network, you know it can be confusing. There’s the alphabet soup of standards—“b,” “g,” “n”— and terms like “dual-band,” “selectable,” and “two radio.” What does it all mean? Below, I explain the basics so you can better understand which wireless router best fits your needs.

Know your Standards
When looking for a wireless router, you first want to check whether it’s “b,” “g,” or “n.” The letters refer to the wireless communication standard on which the router is based: 802.11b, 802.11g, and 802.11n. The first generation of wireless routers was “b,” followed by “g,” and now “n”—the newest generation. The primary difference among the router standards is speed (more on that in a bit) and range.
You won’t find many “b” routers available anymore (except on eBay, perhaps) because it’s old technology. If you’re currently using “b” routers on your network, you should consider upgrading.
Single band vs. Dual band
Wireless communications operate in two bands—2.4GHz and 5GHz. Routers based on 802.11b and 802.11g standards—and some “n” routers—use the 2.4GHz band; however, the 802.11n standard allows wireless devices to use the 5GHz or 2.4GHz band. Routers that operate only in the 2.4GHz band are referred to as “single band”.. Wireless “n” dual-band routers are also available as “selectable” or “simultaneous” models, sometimes referred to as “single radio” or “two radio,” respectively. A selectable wireless “n” router, such as the Cisco RV220W can operate in either 2.4GHz or 5GHz mode; a simultaneous “n” device can operate in both frequencies at the same time.
In Wi-Fi wireless networking, dual band is the capability to transmit on the 5 GHz band of 802.11a and also the 2.4 GHz band used by 802.11b, 802.11g, and 802.11n. Unlike ordinary Wi-Fi equipment that only supports one signal band, dual-band routers contain two different types of wireless radios that can support connections on both 2.4 GHz and 5 GHz.
The 2.4GHz band is the same frequency used by a lot of other wireless devices, such as cordless phones and microwave ovens. Because there are more devices competing for space in this band resulting in interference and congestion, and it may affect how well the router performs both in speed and consistency. The 5GHz band provides better performance and coverage due to less interference.
Speed
Wireless router performance varies by standard with 802.11b providing the slowest speeds at up to 11Mbps. Wireless “g” routers deliver a maximum speed of 54Mbps while devices based on the 802.11n standard are fastest, topping out at 300Mbps.
If you’re thinking faster is better, there’s one thing to keep in mind: a wireless router can’t go any faster than your Internet connection allows. So, under most conditions, a wireless “n” device may only perform at speeds up to 100Mbps. Still, a faster wireless router will increase the speed of your network, allowing employees to access the data they need and making them more productive.
Security
Most routers currently support standard WEP securities as well as the more secure WPA and WPA2. If you want to control what users can access when they are connected to the router, you want to have one that offers decent Access Controls. Cisco’s RV Series Routers have very effective Access Control settings and controls that allow limiting internet use based on time of day. Guest Access and an ability to create multiple SSIDs are also important security measures if you are using the router for a small business. Together, these two features allow you to segment your network into separate areas for guests and trusted users.

Wired Connectivity
Most wireless routers have Ethernet ports for hard-wiring devices to can take advantage of the greater transmission speeds that wired Ethernet has over a wireless connection. For faster transmission rates, invest in a router that has Gigabit Ethernet ports like the Cisco RV220W. Use the Gigibit Ethernet ports to wire devices that access high bandwidth applications such as video and voice, NAS drives, or any other type of multimedia server that have Gigabit Ethernet adapters to take advantage of the faster performance.
Single WAN or Dual-WAN

There’s one other option to consider when deciding which wireless router will best fit your company’s needs—dual WAN. All wireless routers provide a single WAN port that connects your company to the Internet. However, if that port should fail,your business loses access to other offices and any employees working remotely. A wireless router with dual WAN ports, such as the Cisco RV042 Dual WAN VPN Router, ensures reliable connectivity by providing a second link to the Internet and is suitable for businesses that run mission critical applications and cannot afford network downtime.

Wi-Fi : “WiFi” is the short form for Wireless Fidelity. It is a high speed internet and network connection without the use of wires or cables. It means a type of wireless networking protocol that allows devices to communicate and transfer data wirelessly without cords or cables. Wi-Fi is the registered trademark of Wi-Fi Alliance organization who own it. It defines any wireless local area network which is based on Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards.

Devices like video game consoles, camera, mobile etc. which have Wi-Fi functionality can connect to internet by using any wireless access point. Such an access point has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Below is an example of an outdoor wireless access point.

Wi-Fi KEYS : Now the question arises why we are using keys and what is the use of the keys? The simple answer is for security, encryption or for locking. So wireless keys are used for encryption which enhances the wireless security of the network. There are two types of standard wireless key support WEP and WPA encryption. For setting up a wireless key on any network first the administrator will have to select an encryption key WEP or WPA on the router. Then, the administrator sets the same value on each wireless device connecting to the router. Wireless keys are hexadecimal numbers that vary in length (but are typically between 128 and 256 bits long) depending on the encryption method used.

• WEP : The term WEP refers for Wired Equivalent privacy, It is used as a security code for securing wireless networks.
  It is a simple sequence of hexadecimal digits which includes the numbers 0-9 and the letters A-F.
  
  The length of a WEP key depends on the type of WEP security utilized:
  
  i) 40-/64bit WEP: 10 digit key
  
  ii) 104-/128bit WEP: 26 digit key
  
  iii) 256bit WEP: 26 digit key
  
• WPA :
  WPA is a short term for Wi-Fi Protected Access was developed by the networking industry in response to the weaknesses of WEP.
  WPA is called the secure encryption method the reason behind this is that WPA has a function of message integrity check which prevents an attacker from capturing, altering or resending data packets.
  WPA provides stronger encryption than WEP through use of either of two standard technologies: Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES).
  A variation of WPA designed for use on home networks is called WPA Pre Shared Key or WPA-PSK for short. WPA-PSK is a simplified but still powerful form of WPA. Now WPA has been replaced by WPA2 which is more secure and reliable.

TUTORIAL : Mainly we noticed that whenever we are going to crack the Wireless WEP key we always use backtrack and it’s tools. In this tutorial here I am going to show you how to crack WEP keys without using Backtrack and its tools in Windows platform.

Tools required: 1] CommView for Wi-Fi

2] Aircrack-ng (Windows based)

Now open your “CommView” for Wifi and go to “file option” and click on “file capture” like shown in the figure below:


After that a new window appears and then click on “start scanning”.


After scanning its shows the list of all channels and the wireless networks which are running on specified channels as shown in the figure below:




In the above figure I selected a network which is running on channel 6.For details see the right side of the window, it shows the network encryption type, SSID and MAC address. Then click on “capture” and wait for the packet data. You have to create a minimum of 5000 packets for cracking a WEP key. When the numbers of packets are high, it’s easier for you to crack the key as shown in the figure below:

When sufficient packets create the “go to file option”, click on “stop capture”.


After the capturing process is complete, it creates a log file in the “log folder”. You can check your log folder directory by clicking on “log tab”. In the figure below it shows the directory of “my log folder” which is in “my documents/CommView for Wifi/Logs”.


Now go to the log folder there you can see a capture file like shown in the figure below:


Now just double click on the file and a new window appears, then go to “file option” select “export logs” then select “Wireshark/Tcpdump format” and save your file. Here I save my file name as “hack.cap” in my desktop shown in the figure below:


Now open your “Aircrack GUI” and browse for your saved capture file as shown in the figure below:


After that click on the “launch button” then a cmd window appears, asking for index no. of target network here my target network index no. is 1 like shown in the figure below:


After putting in your index number, press “enter” and the cracking process starts, if the key is decrypted successfully like shown in the figure below:


CONCLUSIONS: Hence we conclude that the WEP key is not secured. If we create a 256 bit key that can also be cracked, but that is time consuming and we have to capture a higher number of packets and data.

FIND SERIAL KEY FROM GOOGLE and here is another article of same type how to run trial software for lifetime.

So for this you have to download a simple software called RUNASDATE

WHAT IS RUNASDATE

RunAsDate is a small utility that allows you to run a program in the date and time that you specify. This utility doesn't change the current system date and time of your computer, but it only injects the date/time that you specify into the desired application.
You can run multiple applications simultaneously, each application works with different date and time, while the real date/time of your system continues to run normally.



HOW DOES IT WORK

RunAsDate intercepts the kernel API calls that returns the current date and time (GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime), and replaces the current date/time with the date/time that you specify


PC REQUIREMENTS FOR RUNASDATE

There are no special requirements for this software. RunAsDate works under Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, Windows 7, and Windows 8. Older versions of Windows are not supported. The is also x64 version available in a separated download, for using with x64 applications..

NOTE

This software will work only if the security of software is not good so don't tell them or me if this don't work as many shareware creators are smart enough to detect that the date/time was modified and when they detect the time change, they end the trial period immediately. see my another article on HOW TO FIND SERIAL KEY USING GOOGLE

How to Hack an Email Account

The most frequent question asked by many people especially in a chat room is How to Hack an Email Account? So you as the reader are most likely reading this because you want to hack into some one’s email account. Most of the sites on the internet teach you some nonsense and outdated tricks to hack an email. But here are some of the real and working ways that can be used to hack an email account.

THINGS YOU SHOULD KNOW BEFORE PROCEEDING

Before you learn the real ways to hack an email, the following are the things you should be aware of.

1. There is no ready made software that can hack emails just with a click of a button. Please don’t waste your money on such scam softwares.

2. Never trust any hacking services that claims to hack email passwords just for $100 or $200. Often people get fooled by these services and eventually loose their money with no gain.

3. With my experience of over 6 years in the field of Hacking and Security, I can tell you that there exists only 2 foolproof methods to hack an email. All the other methods are simply scam or don’t work. The following are the only 2 foolproof methods that work.

EASIEST WAY TO HACK AN EMAIL ACCOUNT

Today, with the advent of a program called Keylogger it’s just a cakewalk to hack an email account. It doesn’t matter whether or not you have physical access to the victim’s computer. Using a keylogger is the easiest way to hack an email account. Any one with a basic knowledge of computer can use the keylogger and within few hours you can hack any email account.

1. What is a keylogger?

A keylogger, sometimes called a keystroke logger, key logger, or system monitor, is a small program that monitors each keystroke a user types on a specific computer’s keyboard. Using a keylogger is the easiest way to hack an email account. A keylogger program can be installed just in a few seconds and once installed you are only a step away from getting the victim’s password.

2. Where is the keylogger program available? 

A keylogger program is widely available on the internet. Some of the best ones are listed below

SniperSpy

Win-Spy 

you can also make it by your own
see this post HOW TO CREATE YOUR OWN KEYLOGEER USING VISUAL C ++

3. How to install it?

You can install these keyloggers just as any other program but these things you must keep in mind. While installing, it asks you to set a secret password and a hot key combination. This is because, after installation the keylogger program is completely hidden and the victim can no way identify it. So, you need the Hot Key combination and secret password to later unhide the keylogger.

4. Once installed how to get password from it?

The hacker can open the keylogger program by just pressing the hot keys (which is set during installation) and enter the password. Now it shows the logs containing every keystroke of the user,where it was pressed, at what time, including screenshots of the activities. These logs contain the password of the victim’s email account.

5. I don’t have physical access to the victim’s target computer, what can I do?

It doesn’t matter whether or not you have physical access to the victim’s computer. Because keyloggers like SniperSpy and Win-Spy offers Remote Installation Feature. With this feature it is possible to remotely install the keylogger on the victim’s PC.

You can attach the keylogger with any file such as image, MS excel file or other programs and send it to the victim via email. When the victim runs the file, it will automatically get installed without his knowledge and start recording every activity on his computer. These activities are sent to you by the keylogger software via email or FTP.

6. What if the target user (victim) refuses to run the attached file?

Sometimes the victim may refuse to run the attachment that you send via email because of suspicion. To solve this problem plz refer the following link

A fool proof method to remote install the spy software

7. How can a keylogger hack the Email password?

Hacking an email password using keylogger is as simple as this: You install the keylogger on a Remote PC (or on your local PC). The victim is unaware of the presence of the keylogger on his computer. As usual, he logs into his Email account by typing the username and password. This username and password is recorded and sent to you via Email. Now you have the password of your target email account.

In case if you install the keylogger on your local PC, you can obtain the recorded email password just by unhiding the keylogger program (use your hot key and password to unhide).

8. Which Keylogger is the best?

Both the keyloggers mentioned above are the best for email hacking. However I recommend SniperSpy as the best for the following reasons.

1. Sniper Spy is more reliable than Win-Spy since the logs sent will be received and hosted by SniperSpy servers. You need not rely on your email account to receive the logs.

2. Unlike Winspy, Sniperspy doesn’t require anything to be installed on your computer. To monitor the remote PC all you have to do is just login to your SniperSpy account from your browser.

3. SniperSpy is more easy to use and faster than Winspy.

4. SniperSpy offers better support than WinSpy.

5. SniperSpy has got recognition from media such as CNN, BBC, CBS, Digit etc. Hence it is more reputed and trustworthy.

Hello friends, today I shall show you how to change the logon screen background image in Windows 7. Are you tired and bored of the normal login screen, which you feel is dull? Then worry not, you can put your favourite image as the background picture in the logon screen. Here is how to do it, in just 7 SIMPLE and EASY steps.

•  Go to Start, type “regedit” in the search box. Regedit stands for Registry Editor.

• The registry editor opens up. There, you will find 5 folders, starting with the name HKEY.  HKEY stands for Handle to Registry Key.

• Now, navigate to the following address, starting from HKEY_LOCAL_MACHINE. 

 HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\  

Authentication\LogonUI\Background

• There, on the right, you will find a parameter called “OEMBackground”. Double click on it and in the box below “Value data:”, change the value from 0 to 1. This enables us to put images of our choice at the Login Screen. Close the Registry Editor.

• Now, from My Computer, navigate to the following address -> C:\Windows\System32\oobe. There, create a folder called “info”. Inside that folder “info”, create another folder called “backgrounds”. So inside this folder (C:\Windows\System32\oobe\info\backgrounds), paste your favourite JPEG image, the one you want as your Login screen background.

• Name that image as “background Default” . Note that it strictly has to be named so, else the changes won’t occur. Take care that the size of the image is not more than 256 KB.

• Restart your computer, and when it comes to the Login screen, you will see that your new image is the background of the Login screen.
