Nowadays, using WIFI wireless Internet access has become a way for many netizens to surf the Internet. When you get home, you can open your laptop and easily surf the Internet wirelessly. However, if you often travel around, WIFI Internet access seems to be rarely used. Therefore, many people choose 3G wireless Internet access. However, the speed and price of 3G are not very impressive. Maybe watching a movie online will cost a few hundred yuan. Therefore, it is more reliable to find free WIFI, which is fast, has unlimited traffic, and importantly does not cost money. There are currently free WIFI hotspot signals in many places, but how to find these signals has become a problem for netizens living abroad. The next purpose of this article is to tell you how to find "hotspots"? Where are the free "hotspots" around you that have fast signal speeds and good signals? In fact, only four simple tips are needed
1: Where are the free wireless WIFI hidden?
Step 1: Log in to http://www. wifiok. info is a website where you can check the WIFI access points in major cities and secondary cities across the country. Select a location you want to check and click Next.
Step 2: After a while, you can open the map of the query city. You will see many red * bubbles on the map, which means there are WIFI access points in these places.
Step 3: Of course, not all of these access points are easy to access the Internet. Most of them are hotel access points, so you can't sit in a corner. So, you can select the hotspot category and the display range of the hotspot on the right
Step 4:
1. Click on a suitable hotspot, that is It can display detailed network access provider, location and introduction information, which is very practical
2. Free WIFI Internet access also requires high-speed use of the above URL. We can easily find the approximate location of some free hotspots, but how do we know whether this is covered after we arrive? And what is the speed of the Internet? You can't swim quickly. In fact, it is very simple. Download and install this software called Netstumbler, expand the "Channels" option, and then Netstumbler will start to detect and search the network. Wait a moment and you will see the results. The results include SSID, MAC address, network speed (Speed), network access type (Type), whether there is WEP encryption (Encryption), etc. Through the "Speed" item we can see the wireless access bandwidth of the hotspot. At this time, we only need to connect our wireless network card to the appropriate AP, and then we can start surfing the Internet. It is worth mentioning that NetStumbler can display wireless APs with hidden SSIDs set, and the green light of the AP can be seen flashing in the software interface.
3. Free WIFI Internet access also requires a signal. Want to know whether the signal strength nearby is sufficient? We can also download and install a software called wirelessMON, which is also the software we usually use to test the performance of wireless routing signals to detect the strength of the location of the free wireless signal, so that [continued] free WIFI hotspots can take full advantage. By opening the wirelessMON software, we can intuitively discover all nearby wireless access points, whether encrypted or non-encrypted. Select the free WIFI hotspot we provided earlier and observe the stable performance of the signal for a period of time. As time goes by, we can intuitively understand the strength of the signal, and change the location, direction or location to find the best place for signal demand.
4. The word "encryption" does not exist in my dictionary. You know, 90% of the wireless signals we searched for are encrypted to prevent them from being used. Therefore, you cannot understand the structure of the wireless network, but a software called AiroPeek can do it. AiroPeek is not a pure wireless AP search tool. It has the network packet analysis function of software such as Sniffer, which decodes the 802.11a/b/g protocol and displays management information packets, control information packets and data information packets. I won't go into more details. Practice will bring true knowledge, and we don't encourage everyone to use the Internet. This is unethical behavior. If there are no free WIFI hotspots when you are away, or you can't find an Internet cafe nearby, it can be used for emergencies.
