If you have ensured that the WLAN adapter is integrated into the system, maybe it also configured and a wireless connection is possible, then you can ever find the manufacturer.<\/p>\n\n\n
\ndmesg \n<\/pre><\/div>\n\n\nHere you will find information about the integrated hardware. Among other things, what was connected to the USB. Here should be something like “WLAN adapter” to be found. Mostly here follows the manufacturer and details of the chipset. Often these are Realtek and Ralink.<\/p>\n\n\n\n
Solution: WLAN adapter standard<\/strong> To solve this task, the tool “iw” will be needed, which provides information about the capabilities of the installed WLAN adapter. In general, “iw” must be installed:<\/p>\n\n\n\nsudo apt-get install iw\n<\/pre><\/div>\n\n\nWith the following command you can then display the capabilities of the connected WLAN adapter:<\/p>\n\n\n
\n iwconfig\n<\/pre><\/div>\n\n\nIf something like “IEEE 802.11bgn” is output, then you have the information about the standards supported by the wireless adapter.<\/p>\n\n\n\n
Solution: Channel Support<\/strong> The channels in the frequency range of 2.4 GHz range from 1 to 11 in the US and from 1 to 13 in Europe. It is also different in other parts of the world. Of course, since you’re dealing with Wi-Fi adapters that are made in Asia, it’s of interest to see how much spectrum a specific Wi-Fi adapter is covering.<\/p>\n\n\n\niwlist chan\n<\/pre><\/div>\n\n\nThis will give you a list of the channels (channels) that can be used and which channel is currently in use. For the interfaces “lo”, “eth0” and “enx …”, of course, there is no frequency because they are not WLAN adapters.<\/p>\n\n\n\n
If you want to know more information about the WLAN adapter:<\/p>\n\n\n
