First things first, what exactly is a wireless router? A wireless router has exactly the same functions as an ordinary router but is also a wireless access point and a network switch. They are used to access the internet or a computer network without needing to connect a cable. They can, and often do, function in a wired local area network (LAN).

Next you need to work out what wireless standard you need. Not all routers can support the same wireless standard, so before you begin shopping you need to know if you need one to support 802.11a, 802.11b, 802.11g or 802.11n standards.

You also need to see what speed and frequency your network needs. If you are going to use a super-fast wireless router, your wireless broadband has to be able to support the maximum transmission rate.

Furthermore, you need to make sure that the router you pick will be compatible with the hardware you already have, such as mobile devices. The only way you can do this is by carefully checking.

Wireless security is one of the most important things for you to check when you are buying a router.  You need to pick one which has a firewall feature or a higher level encryption or filtering.  You may be surprised to learn that wireless technology has actually been around for years; however people were reluctant to use it due to the lack of security that it used to provide.

From a practical point of view it is advisable to look at the warranty package that comes with your router.  There can be quite a big difference on the warranties out there. You need to be sensible when choosing, if the router has a better warranty it is likely to mean it is a better product, the manufacturer is happy to support it.

At times I play pranks on my friends by chatting with them in many windows at a time with different screen names. Let’s see how

• Yahoo provides us my profile option to create different profiles. With the help of that you can create and edit number of profiles. Also you can make your profile active or inactive.
• But make sure that keep your e-mail id private so no one can understand that you are same person because yahoo provide you only one e-mail account.
• Sing-in with any profile that will your primary account for that time.
• Open your instant message window; you can see send as option with your profile accounts.
• Send message to any person using one profile; close it before he/she replies you, again open instant message window and send message to that same person using your another profile, so he/she will get two message windows on his/her desktop.
• You can also put different image on display image of each window.
• Like this you can send any number of instant message windows to one person at a time. And he/she will chat with you as different persons.
