i got a laptop with built-in Atheros 5007 wireless LAN (AR2425 chips). and the driver came with ubuntu is not working at all. i also tried ndiswrapper that works but causing a lot of crash. so, after google a lot i found many (somewhat outdated) solutions to make this wireless works but not working anymore...

until i found a ticket at madwifi, then follow this guide. but it's so very long conversation to digest...

so, here i try to summarize it in case i need to repeat the whole steps:

wget http://snapshots.madwifi.org/madwifi-hal-0.10.5.6-current.tar.gz
tar zxvf madwifi-hal-0.10.5.6-current.tar.gz
cd madwifi-hal-0.10.5.6-current/scripts 
sudo ./madwifi-unload
sudo ./find-madwifi-modules.sh $(uname -r)
cd ..
make
sudo make install

that's all it. now i can use the wifi from ubuntu 8.04 hardy.
(it should also works on all other linux distros).

update: reports said it also works on ubuntu 8.10 intrepid.

with the new sober on the wild, many people running wireless network found out that their wireless network suddenly inaccessible.

for wireless newbies, they would thought there's something wrong with their wireless network. perhaps the access point is damaged or something...

but for those experiences a lot with wireless, firewall and virus/worms stuffs, they will quickly notice there's sudden high load on their wireless networks. very high traffic going out their networks.

some people using antivirus gateway, will find out quickly that it's the virus/worms try to spread so fast with few thousands packet per seconds that easily brings down any wireless access point to its knees.
