How can we easily access our laptop when we bring our laptop to an environment without network cables and are unfamiliar with it? Do we have to pay for all kinds of wireless network cards that are expensive? In fact, we can easily connect laptops to the Internet without having to pay for them, because many unfamiliar environments have hidden free wireless Internet access nodes, so how can we find free wireless Internet nodes hidden around us? Next, this article will contribute several tips for finding free wireless Internet access nodes. I hope these skills will help those who often travel and need to access the Internet!
When we are on a business trip to an unfamiliar office area or work environment and confirm that wireless networks are deployed in these locations, we can enable the netstumbler program installed in the laptop, to find out the unencrypted wireless Internet nodes, and then connect the wireless networks in the local laptop to the appropriate wireless Internet nodes through the appropriate settings to enjoy the fun of wireless Internet access.
Sometimes, after finding a free wireless Internet connection node, we don't know where to place the laptop in the room to ensure the fastest wireless surfing speed? As you know, wireless Internet access signals are invisible. If you want to find the best wireless Internet access signal in your room, we also need to use the signal strength detection function of the netstumbler program to find the ideal position for the notebook.
When looking for a signal strength, connect the wireless network adapter in the laptop to a free wireless Internet connection node, and then start the netstumbler program, find the wireless network card device in the laptop from the node list, and then the netstumbler program will be able to display the signal strength detected by the wireless network card in a chart in the area on the right of the program interface, the green color in the chart reflects the signal strength of wireless Internet access, while the red color reflects the noise level of wireless Internet access, from this chart, we can clearly find the location where the wireless Internet access signal is stronger.
TIPS: to improve the security of wireless Internet access, many wireless Internet access nodes use WEP encryption for wireless signals, at this time, netstumbler is often unable to detect the internal communication structure of the wireless network from such wireless signals. However, it doesn't matter. We can use a tool named airopeek to decrypt encrypted wireless signals. This tool can decode WEP encrypted wireless data streams with different lengths in the air, you can steal and analyze encrypted data packets. After decoding encrypted wireless signals, the airopeek tool can display the specific topology of the encrypted wireless network, at the same time, the IP address information and packet sending status of all wireless Internet nodes in the wireless network can be displayed in detail.
