Because of weak WiFi signal I need to use an external antenna (GSI USB Wireless WiFi long range network adapter), which comes with an installation disk including drivers for both Windows and Linux but instructions for Windows only. *In the Linux package there is a Read-me file which gives the following instructions for installation. *The disk includes the suite of files called ./makedrv etc to which the instructions below seem to refer. *But try as I might I can't work out what actually to do with these instructions. *I have tried entering the scripts in the terminal but that does not seem to work. *Would anybody please be able to help me load this driver, explaining what keys I need to press where? *I am very new to Ubuntu. *
Many thanks in advance!

Release Date: 2006-02-09, ver 1.2RTL8187 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 setWireless 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 setMIBs.

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 beforetransmit/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 WPAPSKmechanism (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 &
