Tips to help you work more securely from Wi-Fi hotspots in public

7 tips for working securely from wireless hotspotsWireless hotspots are changing the way people work. These wireless local area networks (LANs) provide high speed Internet connection in public locations—as well as at home—and need nothing more than a mobile PC such as a laptop or notebook computer equipped with a wireless card.
In fact, hotspots are an everyday connection method for travelers and remote workers to browse the Internet, check their e-mail, and even work on their corporate networks while away from the office.
Hotspots range from paid services, such as T-Mobile or Verizon Wireless, to public, free connections. Hot spots are everywhere, including:

  • Coffee shops
  • Restaurants
  • Libraries
  • Bookstores
  • Airports
  • Hotel lobbies
But they all have one thing in common—they are all open networks that are vulnerable to security breaches. And that means it's up to you to protect the data on your PC. In this article, we cover a few tips to make working in public locations more secure.
Try to choose more secure connectionsIt's not always possible to choose your connection type—but when you can, opt for wireless networks that require a network security key or have some other form of security, such as a certificate. The information sent over these networks is encrypted, which can help protect your computer from unauthorized access. The security features of different networks appear along with the network name as your PC discovers them.
Make sure your firewall is activatedA firewall helps protect your mobile PC by preventing unauthorized users from gaining access to your computer through the Internet or a network. It acts as a barrier that checks all incoming information, and then either blocks the information or allows it to come through. All Microsoft Windows operating systems come with a firewall, and you can make sure it's turned on.
To activate the Windows Vista Firewall
  1. Click Start and then click Control Panel.
  2. In Control Panel, click Network and Internet.
  3. Under Windows Firewall, click Turn Windows Firewall on or off.
  4. Ensure that On is selected.
To activate the Windows XP Firewall
  1. Click Start, and then click Control Panel.
  2. In Control Panel, click Network Connections.
  3. In the Network Connections window, under Network Tasks, click Change Windows Firewall Settings.
  4. In the Windows Firewall dialog box, on the General tab, ensure that On is selected.
Monitor your access pointsChances are that there are multiple wireless networks anywhere you're trying to connect. These connections are all access points, because they link into the wired system that gives you Internet access. So how do you make sure you're connecting to the right one? Simple—by configuring your PC to let you approve access points before you connect.
Configure Windows Vista Access Points Windows Vista takes the guesswork out of connecting to hotspots because you are automatically prompted to approve new connections. In addition, after you approve a connection, you assign it a profile for future use.
Configure Windows XP Access Points
  1. Click Start, click Control Panel, and then click Network Connections.
  2. Right-click Wireless Network Connection, and then click Properties.
  3. On the Wireless Networks tab, make sure that the Use Windows to configure my wireless network settings check box is selected.
  4. Under Preferred networks, make sure that the name of the network that you want to connect to is highlighted, and then click Advanced.
  5. Click Access point (infrastructure) network only, and then click Close.
Disable file and printer sharingFile and printer sharing is a feature that enables other computers on a network to access resources on your computer. When you are using your mobile PC in a hotspot, it's best to disable file and printer sharing—when it's enabled, it leaves your computer vulnerable to hackers. Remember, though, to turn this feature back on when you return to the office.
Disable file and printer sharing in Windows Vista
  1. Click Start, and then click Control Panel.
  2. Click Network and Internet, and then click Network and Sharing Center.
  3. Under Sharing and Discovery, click the arrow next to File sharing, click Turn off file sharing, and then click Apply.
  4. Click the arrow next to Printer sharing, click Turn off printer sharing, and then click Apply.
Disable file and printer sharing in Windows XP
  1. Click Start, and then click Control Panel.
  2. Click Security Center, and then click Windows Firewall.
  3. Click the Exceptions tab, and then under Programs and Services, clear the File and Printer Sharing check box.
Make your folders privateWhen the folders on your mobile PC are private, it's more difficult for hackers to access your files.
To make a folder private in Windows Vista Windows Vista not only makes folders private by default, but it also requires passwords for shared folders. As a result, you're already covered! But if you want to double-check, simply right-click on the folder in question, and select Properties. On the Security tab, you can review the set permissions.
To make a folder private in Windows XP
  1. Click Start, and then click My Computer.
  2. Click the drive where Windows is installed, and then click Documents and Settings.
  3. Open your user folder, right-click the folder that you want to make private, and then click Properties.
  4. On the Sharing tab, click Do no share this folder, and then click OK.
Repeat the steps above for each folder that you want to make private.
Encrypt your filesYou can protect your files further by encrypting them, which requires a password to open or modify them. Because you must perform this procedure on one file at a time, consider password-protecting only the files that you plan to use while working in a public place.
Consider completely removing sensitive data from your notebook PCIf you're working with extremely sensitive data, it might be worth taking it off your notebook PC altogether. Instead, save it on a corporate network share and access it only when necessary. This way, you have multiple safeguards in place.
A few simple precautions can help make working in public places more secure. And by selecting the best connections and adjusting settings, you can enjoy productive and safe work sessions no matter where you are.

O2 wifi hotspots not working


The dns info is provided via DHCP which is given out by the hotspot. You may want to A) try and simply reboot the phone and B) go into your settings > wireless and press and hold on the hotspot SSID (wireless name) and forget it. Then re-connect. Otherwise I would say it's an issue with the hotspot.

what is wifi


Hi,
Wireless local area network is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet, uses ethernet protocol.

In simple word allow you to surf internet without any internet cable connection, Wi-Fi enabled device such as a personal computer, video game console, smartphone or digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more (interconnected) access points called hotspots, can comprise an area as small as a few rooms or as large as many square miles. Coverage in the larger area may depend on a group of access points with overlapping coverage.

In addition to private use in homes and offices, Wi-Fi can provide public access at Wi-Fi hotspots provided either free-of-charge or to subscribers to various commercial services. Organizations and businesses - such as those running airports, hotels and restaurants - often provide free-use hotspots to attract or assist clients. Enthusiasts or authorities who wish to provide services or even to promote business in selected areas sometimes provide free Wi-Fi access.


Thanks....!!!

Getting online with your PSP is very simple. First, you must be in range of a Wifi hotspot (wireless local area network). You can adjust network setting to connect to an access point such as a Wi-Fi hotspot or the router on a wireless home network and save the network connections data on your PSP®. Up to 10 connections can be saved.

Once in range of the hotspot, go to "Settings" menu, >> "Network" Settings and press "X" Button. Select "Infrastructure Mode" or "Ad Hoc Mode" and press X Button. Set up the "New Connection". For details about Infrastructure Mode set up, or Ad Hoc Mode set up, visit us.playstation.com. hope this helps.
