Wireless Internet access allows you to spend no money

Wireless Internet access allows you to spend no money. There are many similarities between wireless Internet access and broadband router configuration. The following describes the configuration of wireless Internet access without money. In fact, we can also see some clues about Full wireless Internet access. After the integration, everything is very simple.

How can I access the Internet when you bring your laptop to a strange location without a network cable? Do I have to purchase a high-price "pay-as-you-go" wireless network adapter? Actually, no. There are free "hot spots" in many places "! How can we find out the "hot spots" nearby?

How can I view the connection speed of a wireless network? Most of the time we rely on experience to determine, for example, each Starbucks will provide free WiFi access. However, the selection is too narrow. You can't go out without thinking about the Internet. You have to go to Starbucks. Next we will show you how to find "hot spots "!

TIPS: What is "Hot Spot "?

The so-called "Hotspot", that is, the hot spot, refers to the free or paid way to get the WiFi service, in fact, these places are installed with a wireless router, There is a wireless Internet access signal. General airports, Starbucks, McDonald's, KFC, hotels, and other leisure and entertainment venues all have "hot spots ".

Quickly find free wireless networks

Huagu Network (http://www.hoju.cn) is a specialized community-based website that provides hotspot query and sharing, where you can find out where your region provides hot spots. Open hosts. (See Figure 1)

In addition, the website uses Google Maps to create a national hotspot distribution map. Go to ingress. Click the tag to display the detailed address and contact number of the hotspot. (See figure 2)

Wireless is also high-speed!

Some hot spots can be found through the network, but if you have already arrived somewhere, do you want to know if there are any hot spots nearby? It's actually quite easy.

The results include SSID, MAC address, Speed, network access Type, and whether WEP Encryption exists. Through the "Speed" item, we can see the wireless access bandwidth of the hotspot (see figure 3 ). At this time, we only need to connect our wireless network card to a suitable AP to start surfing the Internet. It is worth mentioning that NetStumbler can display a Wireless AP with a hidden SSID. On the software interface, the green light of the AP is continuously flashing.

Knowledge of wireless Internet access: What is the SSID?

The Service Set Identifier (SSID) is used to differentiate clients in the wireless network. When setting a wireless access point/router. Or a network adapter. This name is also the name of the wireless network you want to access. All wireless devices trying to communicate with each other must share the same SSID.

Is there a strong signal for wireless Internet access?

In addition to scanning wireless access points, you can also use Netstumbler to detect the strength and weakness of wireless signals. For example, when you put the Wireless AP in the study room, you want to know the coverage and strength of wireless signals in the living room, bedroom, kitchen, and other places.

You can select the Wireless AP in NetStumbler to observe the stable performance of the signal for a period of time. Over time, You can intuitively understand the signal strength. (See figure 4) with this method, you can determine where the signal is better, and how to place a Wireless AP to enable full coverage of signals in areas requiring mobile Internet access.

My dictionary does not contain the word "encrypted ".

For general software, when you encounter WEP encryption, you cannot structure the wireless network, but a software named AiroPeek can do this. AiroPeek is not a pure Wireless AP search tool. It provides the network packet theft and analysis functions of software such as Sniffer, that is, decoding the 802.11a/B/g protocol, displays management information packages, control information packages, and data information packages.

Tips for wireless Internet access: AiroPeek supports Decoding of WEP encrypted data streams of different lengths. You can perform aerial decoding by renaming multiple keys, it contains a convenient command line to decode the captured encrypted package file, so even if the wireless signal encrypted by WEP still cannot escape the "finger" of AiroPeek ".

Download and run AiroPeek to view the IP addresses and packet sending statistics of all nodes in the wireless network. AiroPeek displays the network topology in the form, this gives you an intuitive understanding of the network structure (see figure 5 ).

Various information is contained in the data package. In addition to the Source and Destination addresses, the Protocol allows us to view all 802.11-related data packets after sorting, if necessary, you can analyze the data packet content in depth.
