Linux-based wi-fi connection I checked on the Internet and found several related command tools that can be connected. Here, I will make a summary to facilitate future use. For wired NICs, you can use the ifconfig command to plug and launch the network, but for wireless networks: You need to scan the network before connecting. 1. Scan available iw or iwlist: Iw dev wlan0 scan | grep SSID Iwlist scanning | grep ESSID 2. You can use the wpa_supplic

Create a Wi-Fi hotspot in CentOS I recently read an article about setting up wireless hotspots in linux. At that time, I thought it was a novelty. in linux, I could set up wifi. I installed my notebook with centos6.5 last week. The sound card and wireless network card have been installed by myself, and I have not found them. My laptop model is V480C. Here are the steps: System ---- preferences ---- network connection --- add ---- wireless --- New -

Core tips:Comparison of CDMA, GPRS, edge, and Wi-Fi network speeds, we know that the speed of accessing the Internet includes obtaining data from the network and transmitting data to the network, in many cases, the bandwidth or speed in these two directions are different. Receiving speed and upload speedAs you know, the speed of accessing the Internet includes getting data from the network and transmitting data to the network. In many cases, the band

manufacturers, and related products are under development. When the 802.11ac standard is not yet determined, manufacturers will plan their 802.11ac routers in advance to seize the market opportunity. With the launch of products by equipment manufacturers, 802.11ac-related products have gradually entered the carrier's bidding scope. China Mobile has planned to include 5G Wi-Fi products into the collection scope at the beginning of next year, china Tel

I believe that with the development and popularization of wireless technology, more and more wireless products have entered the common market. Many readers have established WiFi wireless networks in their own homes. But do you think it is very troublesome to build a traditional wireless network? You need to know that we had to buy ADSL cats, wireless routers, and so on and connect them smoothly before implementing the wireless LAN. But now we don't have to worry so much. We can use the three-in-

WAPI is the abbreviation of WLAN authentication and privacy infrastructure. Like infrared, Bluetooth, GPRS, CDMA 1X, RFID, and other protocols, it is a wireless transmission protocol. Unlike the above, it is a transmission protocol in a wireless LAN, it is similar to the current 802.11B transmission protocol. There are many kinds of Wireless LAN transmission protocols, including 802.11A, 802.11B, 802.11G, 802.11i and so on, it is developed and certified by the United States WI-

According to the current wireless technology, wireless office networks can be established through infrared, Bluetooth, and 802.11b/a/g wireless technologies. The data transmission rate of infrared technology is only 115.2 Kbps, and the transmission distance is generally only 1 meter. The data transmission rate of Bluetooth technology is 1 Mbps, and the communication distance is about 10 meters; the data transmission rate of 802.11b/a/g reaches 11 Mbps, and the effective distance is up to 100 met

The figure in Ubuntu12.04 shows that wifi wireless hotspots have broadband in both the room and dormitory, and computers can access the Internet. But without wireless connection, how can I access the Internet through a mobile phone? Ubuntu12.04 how to set up a wireless hotspot to share the network between the mobile phone and the computer? Very simple. no shell command is required. you only need to set a Wi-Fi hotspot in Ubuntu 12.04 in the graphic in

To prevent security leaks in Wi-Fi networks, You can restrict devices on wireless nodes to Ensure network security. In the subsequent articles, we will introduce other methods and impose security restrictions to prevent security leaks. Some may ask how to restrict wireless devices? Do you have to lock the wireless node devices in the Local Wireless LAN? In fact, for many models of wireless node devices, the default passwords they use at the factory a

Two common encryption methods: WEP and WPA Currently,WirelessThere are already several encryption technologies in the network. WEP and WPA are the most common encryption methods. 802.11 Wired Equivalent Privacy (WEP), the first security protocol for a wireless LAN, has been questioned. Although WEP can prevent hackers from entering the wireless network, there is still reason to doubt its security, because WEP is very easy to crack, just like a plastic lock on the door.
