wifi接收器驱动程序

Release Date: 2006-02-09, ver 1.2 RTL8187 Linux driver version 1.2 --This driver supports RealTek RTL8187 Wireless LAN driver for Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006, SUSE 9.3/10.1/10.2, Gentoo 3.1, etc. - Support Client mode for either infrastructure or adhoc mode - Support WEP and WPAPSK connection < Component > The driver is composed of several parts: 1. Module source code stack.tar.gz drv.tar.gz 2. Script ot build the modules makedrv 3. Script to load/unload modules wlan0up wlan0down 4. Script and configuration for DHCP wlan0dhcp ifcfg-wlan0 4. Supplicant source code: wpa_supplicant-0.4.9.tar.gz 5. Example of supplicant configuration file: wpa1.conf < Installation > Runing the scripts can finish all operations of building up modules from the source code and start the nic. 1. Build up the drivers from the source code ./makedrv 2. load the driver module to kernel and start up nic ./wlan0up < Set wireless lan MIBs > This driver uses Wireless Extension as an interface allowing you to set Wireless LAN specific parameters. Current driver supports "iwlist" to show the device status of nic iwlist wlan0 [parameters] where parameter explaination [parameters] ----------------------- ------------- Show available chan and freq freq / channel Show and Scan BSS and IBSS scan[ning] Show supported bit-rate rate / bit[rate] Show Power Management mode power For example: iwlist wlan0 channel iwlist wlan0 scan iwlist wlan0 rate iwlist wlan0 power Driver also supports "iwconfig", manipulate driver private ioctls, to set MIBs. iwconfig wlan0 [parameters] [val] where parameter explaination [parameters] [val] constraints ----------------------- ------------- ------------------ Connect to AP by address ap [mac_addr] Set the essid, join (I)BSS essid [essid] Set operation mode mode {Managed|Ad-hoc} Set keys and security mode key/enc[ryption] {N|open|restricted|off} For example: iwconfig wlan0 ap XX:XX:XX:XX:XX:XX iwconfig wlan0 essid "ap_name" iwconfig wlan0 mode Ad-hoc iwconfig wlan0 mode essid "name" mode Ad-hoc iwconfig wlan0 key 0123456789 [2] open iwconfig wlan0 key off iwconfig wlan0 key restricted [3] 0123456789 < Getting IP address > After start up the nic, the network needs to obtain an IP address before transmit/receive data. This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS" command, or using DHCP. If using DHCP, setting steps is as below: (1)connect to an AP via "iwconfig" settings iwconfig wlan0 essid [name] or iwconfig wlan0 ap XX:XX:XX:XX:XX:XX (2)run the script which run the dhclient ./wlan0dhcp or dhcpcd wlan0 (Some network admins require that you use the hostname and domainname provided by the DHCP server. In that case, use dhcpcd -HD wlan0) < WPAPSK > WPA_SUPPLICANT help the network to communicate under the protection of WPAPSK mechanism (1)Unpack source code of WPA supplicant: tar -zxvf wpa_supplicant-0.4.9.tar.gz cd wpa_supplicant-0.4.9 (2)Create .config file: cp defconfig .config (3)Edit .config file, uncomment the following line: #CONFIG_DRIVER_IPW=y. (4)Build WPA supplicant: make If make error for lack of <include/md5.h>, install the openssl lib(two ways): 1. Install the openssl lib from corresponding installation disc: Fedora Core 2/3/4/5(openssl-0.9.71x-xx), Mandrake10.2/Mandriva10.2(openssl-0.9.7x-xmdk), Debian 3.1(libssl-dev), Suse 9.3/10.0/10.1(openssl_devl), Gentoo(dev-libs/openssl), etc. 2. Download the openssl open source package from www.openssl.org, build and install it. (5)Edit wpa_supplicant.conf to set up SSID and its passphrase. For example, the following setting in "wpa1.conf" means SSID to join is "BufAG54_Ch6" and its passphrase is "87654321". network={ ssid="BufAG54_Ch6" proto=WPA key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP WEP104 WEP40 psk="87654321" priority=2 } (6)Execute WPA supplicant (Assume 8187 and related modules had been loaded): ./wpa_supplicant -D ipw -c wpa1.conf -i wlan0 &
