<html> <head> <style></style> </head> <body class='hmmessage'> <style></style> <font class="Apple-style-span" face="Tahoma" size="2">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. </font><div style="font-family: Tahoma; font-size: 10pt; "><br></div><div><font class="Apple-style-span" face="Tahoma" size="2">Many thanks in advance!</font><br><div style="font-family: Tahoma; font-size: 10pt; "><br></div><div style="font-family: Tahoma; font-size: 10pt; ">READ ME FILE BEGINS</div><div style="font-family: Tahoma; font-size: 10pt; "><br></div><div><div><font class="Apple-style-span" face="Tahoma" size="2">Release Date: 2006-02-09, ver 1.2</font></div><div><font class="Apple-style-span" face="Tahoma" size="2">RTL8187 Linux driver version 1.2</font></div><div><font class="Apple-style-span" face="Tahoma" size="2"><br></font></div><div><font class="Apple-style-span" face="Tahoma" size="2"> --This driver supports RealTek RTL8187 Wireless LAN driver for </font></div><div><font class="Apple-style-span" face="Tahoma" size="2"> Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006, </font></div><div><font class="Apple-style-span" face="Tahoma" size="2"> SUSE 9.3/10.1/10.2, Gentoo 3.1, etc.</font></div><div><font class="Apple-style-span" face="Tahoma" size="2"> - Support Client mode for either infrastructure or adhoc mode</font></div><div><font class="Apple-style-span" face="Tahoma" size="2"> - Support WEP and WPAPSK connection</font></div><div><font class="Apple-style-span" face="Tahoma" size="2"><br></font></div><div><font class="Apple-style-span" face="Tahoma" size="2">< Component ></font></div><div><font class="Apple-style-span" face="Tahoma" size="2">The driver is composed of several parts:</font></div><div><font class="Apple-style-span" face="Tahoma" size="2"><span class="Apple-tab-span" style="white-space:pre"> </span>1.
