Notebook And WiFi Standards

All modern notebook Wi-Fi is activated, allowing Internet access from anywhere in the world. But while using the wireless notebook, you should be aware Wi-Fi standards, hotspots, as well as the effective use of this technology to make the best use of your notebook.

The 802.11g Wi-Fi standard is the last rule, which follows its notebook when you are online. The Wi-Fi alphabet spaghetti consists of protocols such as 802.11, 802.15, 802.16 and 802.20. However, for most notebook users with added 802.11 would be sufficient a & 39;, b or g .

There are protocols such as and , h , i and n that are waiting in the wings to make your application. However, from now on, 802.11g is the only protocol that it is necessary to think regarding wireless connectivity. The latest Wi-Fi is the standard 802.11ge offers connection speeds of up to 54 Mbps in the 2.4 GHz radio bands, which is five times more than the previous standard 802.11b. It is more stable, more secure and compatible behind.

Almost all notebooks that are manufactured today are standard 802.11g Wi-Fi ready. This standard is designed to replace the older Wired Equivalent Privacy or WEP, specifying the Wi-Fi Protected Access or WPA. The WPA will act as a temporary solution, until the next standard, 802.11i network security standard is implemented with a new algorithm called Temporal Key Integrity Protocol, which will be much more secure and reliable.

However until the new standard is implemented, the 802.11g is being followed. There are only two drawbacks of this notebook with Wi-Fi standard, which, firstly, because it is a new standard, it may not perform as promised, and second, with fast latest emerging technologies, which could become obsolete by new standards before you have the time to take advantage of it.

Few tips for a secure Wi-Fi experience:

Atualiz them frequently to ensure the protection of the latest hackers and viruses. You should always keep the feature on cryptography to ensure safe navigation with WiFi

2 - Along with the software, you should also consider upgrading better hardware. Hackers have always found 802.11ae 802.11b very easy to cut. However, 802.11g, it is more difficult to crack and you should consider upgrading your hardware for a g card. 802.11g is backward compatible with IEEE 802.11b, 802.11g can leverage the widespread, international adoption of IEEE 802.11b in products from laptops to PDA A personal firewall such as ZoneAlarm or significantly BlackICE can add up to the level of safety of your notebook.

3 - When you are using your notebook on a Wi-Fi hotspot, make it a point not to send data. While you are browsing, not enter your credit card number, expiration date, passwords, bank account numbers, etc. Sensitive data are goldmines for hackers, and they will smear your bank account before you can finish saying, & quot; I have been a victim of identity theft online!

4 - Consider not be online while working. If the risks outweigh the benefits, then it would be better to remain offline, at least until the new 802.11i standard is not implemented. Still, the security can be breached, albeit with difficulties. If you do not need Wi-Fi to implement its work, and then get off. If you need the Wi-Fi only to send and receive files, then be connected only to that period. Rest of the time, remain offline.

Precautions to lead to a public Wi-Fi hotspot:

Whenever you are in the public domain, it is necessary to take precautions because it is free for all. Wi-Fi hotspots are available for each and every person, and nobody can be connected. Besides online theft, there is also the risk of theft offline.

While in a public hotspot, is not so absorbed with your notebook, you fail to notice the people around you. There are people who are in the business of stealing notebooks, from public hotspots. And they do not work as individuals but as a gang.

Also while you are online in a public hotspot, follow simple rules to encrypt files before transfer or sending them, making sure that it is connected to an access point legitimate, and file sharing is turned off. Basic precautions such as password protect your notebook, updating your system periodically, and using antivirus software must be strictly followed. For more online security, consider using a personal firewall, a virtual private network (VPN), and email with secure http (https).
