<> <> Realtek 8180L is a very common chip set found in many devices (eg. Acer Aspire 1356LCi laptop). It is identified with '''lspci''' command as {{{ 00:09.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8180L 802.11b MAC (rev 20) }}} In Ubuntu 6.10 (''Edgy Eft'') it is supported out of the box with a open-source driver. This driver supports unencrypted networks and WEP protected networks. However it looks like more advanced encryption (like WPA) is not available with open-source driver (see [[http://www.archivesat.com/Ubuntu_user_technical_support/thread2369270.htm|this]] and [[http://groups.google.com/group/alt.atheism/browse_frm/thread/d80ee719b0aae783/dc7b26f2d3183af8?lnk=st&q=ieee80211_rtl+wpa&rnum=1&hl=en#dc7b26f2d3183af8|this]]). However it is possible to install binary driver from Realtek with help of ndiswrapper and thus have access to more advanced encryption. Steps for instalation: 1. Install following packages: ndiswrapper-common ndiswrapper-utils-1.8 ndisgtk wpasupplicant network-manager network-manager-gnome. 1. Find a binary driver for Windows 98 Second Edition on [[http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=26&PFid=5&Level=6&Conn=5&DownTypeID=3&GetDown=false&Downloads=true|Realtek]] site and download it ([[ftp://202.65.194.211/cn/wlan/ndis5x-8180(173).zip|direct link]]). 1. Unpack downloaded zip file to /opt (root privileges might be required). 1. Disable open-source driver (it will conflict with closed source). Open /etc/modprobe.d/blacklist file with text editor (eg. with gksudo gedit /etc/modprobe.d/blacklist). Then add the following two lines to the end of the list: {{{ blacklist r818x blacklist ieee80211_rtl }}} 1. Go to System->Adminsitration->Windows Wireless Drivers and install downloaded driver.
