Problem of wireless network drop down of rtl8187 adapter in ubuntu gutsy 8.04 is a huge problem.

Because many notebook use rtl8187 wireless on board chipset and have a problem about drop down connection (eg. in firefox status bar is LOOKING UP… or other program is disconnect from internet). Now I found solution to solve this problem. Please read this carefully and do it.

Step1. open terminal and type commands

ifconfig wlan0 down
rmmod r8187 rtl8187 2>/dev/null
wget http://dl.aircrack-ng.org/drivers/rtl8187_linux_26.1010.zip
unzip rtl8187_linux_26.1010.zip
cd rtl8187_linux_26.1010.0622.2006/
wget http://patches.aircrack-ng.org/rtl8187_2.6.24v3.patch
tar xzf drv.tar.gz
tar xzf stack.tar.gz
patch -Np1 -i rtl8187_2.6.24v3.patch
make
make install

depmod -ae
echo “r8187″ >> /etc/modules or sudo gedit /etc/modules and add r8187 and save
echo “blacklist rtl8187″ >> /etc/modprobe.d/blacklist or sudo gedit /etc/modprobe.d/blacklist and add blacklist rtl8187 and save

reboot your computer.

Step2. install WICD it is easy to install in ubuntu. Open Synaptic package manager and add new repositories (for other distributions see http://wicd.sourceforge.net/download.php for instruction.)

deb http://apt.wicd.net gutsy extras (This is in gutsy,other distribution type other version. eg. dapper, edgy, feisty, gutsy, hardy)


Click reload and find package of WICD. ( type wicd in search box) install it. or open terminal and type sudo apt-get install wicd

Step3. Config your Wireless network name in WICD and other information to connect to your wireless router.

Cheer you can do it!!!
