Of all the network solutions available, wireless internet gives you the freedom to be online without the need for extensive cabling. However, wireless internet is also more vulnerable to cyber attacks – particularly if it is inactive for long periods of time. If you are having trouble with your wireless network, the following list of network support pointers should help to set you right.
1) Power cycle the system by shutting it down and switching it back on after 30 seconds.
2) Check the network settings in order to verify the IP address and other related information.
3) Determine whether your network card is working adequately.A way to identify a malfunctioning adapter is by disabling the cards one by one.
4) Try moving a portable host (e.g ypur laptop) closer to the router. If it works better, interference of low signal strength is the reason for the poor internet access.
5) Remember to check the functionality of the wireless router and access points. Adjust the antenna to get an optimum signal.Most wireless routers should come with omni-directional antennae to send signals in all directions – a situation appropriate for a square shaped network.
6) Try changing the location of the router and access point. Ideally they should be placed central to all of the computers.
7) Examine signal performance by using the monitoring utility that typically comes with the access point.
Check your devices are showing the correct lights. There is no universal standard to indicate wireless router functionality so make sure that you check the devices manuals to see which lights indicates what function.
9) Use wireless internet connection utilities to check the SSIDs and channel’s neighbouring wireless networks are using.
10) Check that all the correct drivers have been installed.
11) Check the config settings for encryption keys.
If you are still struggling then it can be a good idea to contact the manufacturer of your wireless router or a network supervisor.

It was in 1999 that Compaq launched iPAQ having the functions of a pocket personal computer and a personal digital assistant (PDA). With the acquisition of Compaq by Hewlett Packard, the products began to be marketed as HP products. iPAQ combines the functions of mobile phone, palm top computer, PDA and smart phone. It also has GPS facility, wireless networking, a card reader and Bluetooth interface. The Microsoft Windows interface gives iPAQ all the benefits of having multimedia capabilities.
There are very many applications in PDAs. The user can actually decide what kind of applications are to be incorporated. PDAs have applications that are useful in medicine. It assists in diagnosis of disease, treatment and the selection of drugs. It can record symptoms as well as present information on treatments. PDAs are applied in the educational field, particularly by students. The relevant tasks that it can execute are digital note taking and its modification, the spell-check, dictionaries, e-books storage and use, digital planning lessons, word processing and many others. It finds application in the field of sports in the calculation of speed, distance and time; pre-flight planning and assistance to the glider pilots in navigation linked to the use of GPS, and for road rallyist with GPS assisted navigation.
Digital Equipment Corporation Western Research Laboratory (WRL) developed iPaq originally. It runs on an Intel Pentium III processor or an Intel Celeron processor with a processing speed of 500 MHz to 1 GHz. It has a memory ranging from 128 MB to as much as 512 MB. The memory can be upgraded also. Some of the popular handheld PDA gadgets are Palm TX Handheld, HP iPAQ 111 Classic Handheld, Nokia N810 Portable Internet Tablet, Palm Tungsten E2 Handheld, Asus A626 3.5-inch PDA Windows Mobile 6.0, HP iPAQ 210 Enterprise Handheld, Sony Ericsson C905i Unlocked Cell Phone and Nokia 02700T6 N810 WiMAX Edition Portable Internet Tablet.
Our life is no longer the same. Mobile technologies have drastically changed the way we work and live. For instance, mobile shopping and mobile banking save lot of our time, energy and worry besides its convenience and ease. We now make use of PDAs for such diverse use as getting to know about the weather, knowing the sports score and getting the stock quotes. It is fast becoming a device without which we will not be able to function and carry out our day to day activities.
