[Help] wireless networks cannot be found in Hongqi linux6.0

[Help] wireless networks cannot be found under Hongqi linux6.0-Linux general technology-Linux technology and application information. The following is a detailed description. I was the first time in contact with linux cainiao, my computer configuration is as follows: motherboard Asus P5GC-MX; 1g memory; 80g hard disk; onboard sound card graphics card; in addition with a TP-LINK TL-WN321G wireless network card, a TP-LINK TL-WR541G wireless router, the installation is the Red Flag 6.0 desktop system.
The installation of the security tutorial system has been completed. After the network cable is connected to the onboard Nic, the system can access the Internet. However, the Wireless AP cannot be found in the wireless Nic icon on the taskbar icon in the lower right corner, and the wireless Nic is removed, the icon in the lower-right corner disappears (I think the system can recognize the wireless network card ).
Please help us solve this problem. cainiao will give you a gift here!
