Due to project work requirements, point-to-point and multi-point transmission of wifi must be implemented on the embedded E9 platform.
WiFi module chip: Reiling 3070 Chip
Embedded platform: E9 (ARM)
Cross-compilation environment: Arm-None-Linux-gnueabi
1. First download the driver for the Wi-Fi module
2. Cross-compile the driver
A. open the file after decompression of the driver file. If you need WPA and other functions, you can enable./OS/Linux/co
, generally expressed as Leni = I + 1)
The key code is as follows:
/* Note: int next [] is the next array, int arr [] is the array for finding a regular, and Len is the array length */next [0] = 0; for (INT I = 1, q = 0; I View code
The minimum cycle is 42.
Another way to find the rule is to directly search for the value of F % 7 in the table, and the cycle found according to the above method is 294. The following is very simple ~

Recently, I purchased a wireless route and a wireless network card. to test its performance, the first step is not to link them together and access them effectively.
Internet does not belong, so I began to look for information and information everywhere.
First, find the source code of the driver Module,
TP-LINK wireless network card official does not provide Linux driver, but in fact the wireless network card driver mainly depends on the chip model used by the wireless network card, in this way, we can download the corresponding driver from the chip vendor's official website (compile and install it by ourselves ).
The system does not seem to have any response when a wireless network card is inserted. Do not worry, enter the command on the terminal

If you are learning about Linux, you have installed Linux on your computer, but you often need to access the Internet. There is no wireless network adapter in Linux, here we will introduce you to the installation of the DWL G122 driver module for the Linux wireless network card. I hope you will learn how to install the DWL G122 driver module for the Linux wireless network card.
First, find the source code of the driver Module, which can be obtained from the company website of

For the sake of interest, if you want to connect to a wireless wi-fi network in multiple places, the key is required. So it took me a few days to try the attack on the Internet. The process was as follows:
1. My Nic model is rt73 USB wireless LAN card. The above name is the complete name displayed in the Device Manager. I have downloaded the complete factory driver in XP, however, no driver is installed in Ubuntu.
2. First, you need to know the name and channel number of the target Wi-Fi network
