In win7, use a laptop to send a Wi-Fi signal so that the mobile phone can access the Internet wirelessly!

Note: Upgrade the wireless NIC Driver of the notebook to the latest version. Some old drivers do not support the Wireless AP mode. Note: When the wireless network adapter is changed to AP mode by the following steps, it cannot be used for Internet access at the same time. Therefore, you must ensure that the laptop is connected to the Internet through a wired network. 1. Run the command prompt as an administrator: Click Start> All Program-"Attachment", find "command prompt", right-click, and select "Run as administrator ". 2. Enter the command netsh WLAN show drivers in the command prompt and find "supported bearer network" in the output content to see if "yes" or "no" is written later ". If it is "no", it means that your wireless network card does not support AP mode. You do not need to do the next step... 3. enter the following command in the command prompt: netsh WLAN set hostednetwork mode = allow SSID = the name of the wireless network you want key = the password you want to set (the password must be at least 8 characters long, otherwise, it is invalid ). Command will prompt that the bearer network has been started and so on, just ignore it. 4. choose "Control Panel"> "network and Internet"> "view network status and task"> "Change adapter Settings", and you will find that a Microsoft Virtual WLAN miniport adapter is added, this is the wireless network adapter we have virtualized in step 3. 5. Enter the command netsh WLAN start hostednetwork in the command prompt. Open a virtual wireless router. 6. open "Network Sharing Center" and you can see that you are now connected to two networks, one is your wired network, and the other is the virtual network (the notebook usually shows "Wireless Network 2 "). 7. in "Modify adapter Settings", right-click "Local Connection" (the wired network card that you connect to the network), select "properties", and click "share ", select the "allow other network users to connect through the Internet connection of this computer" option, select the created virtual network (generally "Wireless Network 2") from the drop-down menu, and click OK. (If you cannot find this option, restart your computer before you can find it.) At this point, the Wireless AP you have created using the wireless network card has been completed. Enable the WiFi function of your mobile phone, search for wireless networks, find the wireless name in step 2, and enter the password in step 2. After the connection is successful, you can access the Internet. Supplement: If you want to cancel the AP mode of the wireless network card, restart your computer.
