Can't I find a wireless signal on my computer or mobile phone? I believe many people have come across this article, this article will introduce some high frequency faults and provide solutions. The following system home Xiaobian will introduce you to the notebook can not find WiFi. First, let's make a hypothesis that your computer's wireless network card driver is normal. When the driver is normal, we can see the project “Wireless Connection” in the network connection interface. (The phenomenon of not finding any wireless signal) [Windows wireless configuration service is turned off] In xp, the wireless configuration service name is "wireless zero configuration", and the name in Windows 7 is "WLAN AutoConfig". Check if this service is activated. The method is as follows: Enter services.msc in the run, press Enter, open the service console, find the service item, see if its status is “” has been started”, otherwise it will be started. [Wireless switch is turned off] This is a simple and simple method for many notebooks, which is complicated and complicated. Some notebook switches are more obvious, it is a hard switch, and some are on the side of the notebook or above the keyboard, you can toggle to the left and right. Some notebooks are above the keyboard and are buttons that can be pressed, even touch buttons. What makes people crazy is that some notebooks use the keyboard function keys to control, for example, you need to press Fn+F8 to turn the wireless function on or off. If the drive is normal, nothing can be missed. The function keys on the notebook do not belong to the standard keys of the keyboard. It needs to be driven by the manufacturer's hotkey to operate normally. Otherwise, we will not reflect anything after pressing the function keys. If the hotkey driver is not installed, it is recommended to download it from the official website, such as the download interface of Lenovo below. There are even switches in the BIOS settings. For example, the wireless LAN radio of thinkpad below needs to be set to on (some people don't know how to do it, this is off, Baoyun has encountered a lot). [Wireless channel problem] This generally occurs in the individual "parallel" parallel machine, as well as the old notebook. The reason is that the allowable range of 2.4 GHz wifi channels varies from country to country, from 1 to 11 channels in the United States, 1 to 13 channels in Europe and China, and 1 to 14 channels in small Japan. If you are unfortunate enough to encounter a router that automatically selects a channel of 12 or later, and the notebook network card only supports 11 channels, then your notebook will not be able to search for this signal anyway. However, this phenomenon is different from the above, this has at least other signals in the wireless signal list, and can not see its own signal. And other than this computer can not search, others can search. The solution is to set the channel to one of 1, 6, and 11 in the router (recommended for these channels that do not interfere). [SSID for Chinese name] There are some mobile phones that do not recognize the SSID of the Chinese name (the name you see when searching for wireless). Is this modification simple? Not much to say.
