Hello guys, it is my first post here and seeking for help to install my wireless card.

I bought this pc 3 weeks ago and i did a dual boot with win xp. First i installed the 64 bits version of ubuntu and it "didnt work" and then i decided to install the 32bits version and i had the same result :(

I installed it in both version using madwifi/ndiswrapper and at the end i arrived at the same point. Ubuntu recorganise my wireless card and yesterday i could scan the network and even try to connect to it, but today is it not working the scan anymore :(

I'll post my info here

* 1) The strangest think here is that the wireless name is different from the name that windows shows me. When i run windows it tells me that my wifi card is Atheros 5007EG and the name shown above (in bold) is different.

* 2) I dont know what this wlan0:avahi do. This is the one interface who gets ip. When i tried with madwifi same think happend just the name of the interface was different (ath0 and atho:avahi). My first thought about it it could be from the bluetooth interface this ip.
I also tried to disable it, but when i do it, wlan0 disappears from the ifconfig list too

Please can someone help me to solve this problem? I've read a lot of post and followed a lot of how tos and some didnt work and the one that "worked" brings me back to this situation. I'm totally lost here!

Hi, The best combo for wireless running linux is using ndiswrapper and the windows driver.

For handling wireless connections, encryption, etc..
Check out wicd at sourceforge (http://wicd.sourceforge.net/).

It's by far the best wireless config utility I've used for linux. I actually uninstalled gnome and knetworkmanager and stick with wicd.
It handles wireless and wired connections.

As far as ndiswrapper is concerned I've sometimes had to install/reinstall the driver

make sure to sudo ndiswrapper -m to load module at startup

Hi josmcc, im using ndiswrapper atm, and i puted all modelues to /etc/modules to start up at tne boot time. I really dont know what else i can do make my wifi work. Ive followed all tutorials, how tos and everyone who works, brings me back to the situation discribed above.

I started having problems with wifi recently, which led me to use wicd.

I kept losing connection,had to reboot, reinstall ndiswrapper, etc, to get it to work.

I uninstalled network-manager-gnome and knetworkmanager, which I think may have had something to do with it.

The problem with Wlan in linux displaying differently may be due to driver, I'm not really familiar with madwifi, but I think that is a generic driver for atheros chipsets.(that is probably why is displaying wrong)

I would boot into windows, find which .inf and .sys you need for the wireless network card, and use those with ndiswrapper, then install wicd.

Also, make sure when you install the drivers using ndiswrapper, you are installing driver as root (sudo)

Hope this helps, and you eventually get it to work, I'm kind of new to linux also, but been messing with it on and off for a while and recently decided to stick with it as only OS on my laptop.

From above it looks like you're getting automatic Private Ip for the Wireless card, so it may just be a DHCP issue. Try installing wicd. That is what fixed my wirless issues.
