TipsTipsTipsTips forforforfor Wi-FiWi-FiWi-FiWi-Fi users users users users With a Wi-Fi connection, you can roam about 150 m around the access point (depends on different environment), so find a spot where you can work without any interruption. Then see how much work you can do, such as:
Easily and quickly receive and transmit files within your local network no problem for big files. Access your email and surf the web with the same speed as that connected with network cables. Synchronize data between devices. Take advantage of wireless printing send files directly from your laptop PC to a wireless printer over Wi-Fi connection. 6.6.6.6. Warning Warning Warning Warning Wi-Fi offers greater speed and range than Bluetooth, but it drains your portable device batteries a lot faster than Bluetooth does. In fact, if you use a Wi-Fi connection regularly on your laptop PC, you'll undoubtedly notice that you need to recharge more often. If you need to conserve battery life on a long trip for example turn off your Wi-Fi connection when you don't actually need it. 7.7.7.7. Security Security Security Security Because wireless networks rely on radio signals to transmit data, they are not as secure as wire network. Wireless networks are susceptible to viruses and breaches like eavesdropping and need to be protected in order to be secure. There are many security measures to safeguard wireless networks, protect the data, and keep unauthorized users out. Hotspots, on the other hand, are often free of standard security practices in an effort to make it easy for anyone to connect. It may be found that some pay hotspots administered by service providers offer have some level of security, however, when using a hotspot, its always a good idea to be proactive and to employ security measures of your own. 8.8.8.8.
