Wifi doesn't work in Asus eee PC

Hello all, this is my first post around here.

I've decided to try something new and remove Lubuntu from my eee pc 900. Motivated by the advertised lightweightness and extreme configurability, I decided to go ahead and install Arch Linux in it.

The documentation in the Arch Wiki and the installation process were all incredibly detailed, and the installation from usb was successful.

Partly because some packages were considerably big, I decided to use pacman with cable connexion which went flawlessly. I proceeded to install LXDE and a couple of programs (firefox, pidgin etc). But after all that was done, I wanted wifi and couldn't get it to work.

I have read over and over this page <<https://wiki.archlinux.org/index.php/Wireless_Setup>> but still cannot manage to configure it. According to Ubuntu's documentation, my wifi card (Realtek RTL8180) is supported out of the box, so I don't think there are drivers necessary to install. I also managed to install the "base-dev" during the installation process, so I don't think that may be the problem. Also, as I run "iwconfig" the device is detected, but "dhcpcd wlan0" fails to connect it (whereas it works for eth0).
I've tried Wicd and NetworkManager, neither seem to do the trick.

Could someone help me with that or point me to some more detailed explanation?

Thanks!

Re: Wifi doesn't work in Asus eee PC

Need moar infozzzz ... (stops being a script kiddy)

- What kind of wifi connection are you trying to get, IE which encryption method (Wpa2 or Wep? or None?)
-please paste the output of --

lspci|grep net and ifconfig -a

Also are you using netcfg now or still with wicd and network manager?  Can you ping your router (assuming you have one and are not directly connected to your cable modem)?

Thanks for the quick reply. Moar info to follow:

-My connection is WEP encrypted and:

I'm still with wicd here. Haven't tried netcfg yet. And yes, I can ping it, and it's through a cable connected there that I am posting this.

Re: Wifi doesn't work in Asus eee PC

Hmf my bad, I'd like to see what kind of chip your wifi uses, IE the eth0 one is an Atheros, but is the wireless one Atheros too or something else?

Humour me and try to use netcfg with a wep profile.  The wiki has a good explanation of how to do this IIRC.  If it doesn't i'll just paste my file for you to copy (which i'd do right now but I'm on win7 without a wifi connection on Arch too!)

OK question time again so please pay attention  big_smile

I found this in the wiki but I want to know if this applies to your case:

You can add wicd-client to your DE/WM startup to have the application start when you log in.
Note: Some users have had an issue with two wicd-client processes when using this method. There has been discussion about this in the Arch forums and Arch bug reports (see Wicd#External_links). It appears that the wicd package puts a file in /etc/xdg/autostart/wicd-tray.desktop, which will autostart wicd-client upon login to your DE/WM. If this is the case, you will have two wicd-clients running if you add an additional wicd-client to your DE/WM startup file. Should that occur, confirm that the wicd-tray.desktop file exists in /etc/xdg/autostart; if so, having wicd in the daemons list of /etc/rc.conf is sufficient.

Also, I'm not sure if Hal is still necessary but if it isn't then you may want to get rid of it (if you had it to begin with...omg I hope that made sense).

Try to use dhclient instead of dhcpcd?  You can ping the router which means it IS connected through a wire so it's not the router.

Try this?

If wicd can get an IP address for a wired interface and is unable to get an IP address for a wireless interface, try disabling the wireless card's powersaving features:

 iwconfig wlan0 power off

Could you post a copy of the error message(s) showing up when you try to connect?  Is there a message when the connection is succesful?

Oooooooooh look what I found https://wiki.archlinux.org/index.php/Asus_Eee_PC_901 !

Re: Wifi doesn't work in Asus eee PC

So I got netcfg installed through pacman and as I try to run it I get the help message. Should I still keep wicd? I tried to run wicd-client but nothing seems to happen (no connection, no system tray change...)
The wifi chip given by lspci is Realtek Semiconductor Co., Ltd. RTL8187SE, which I can't seem to find among the documentation (it has 8187 and 8187b only)
This is what I get from your code:

$ iwconfig wlan0 power off
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not permitted.

dhclient also seems to fail. Netcfg seems to be asking for a profile, but apparently there aren't any. How can I add one?

Thanks for the information on the 901, but it seems a little obsolete since it refers to older kernels and I just upgraded to 3.0

I'll be looking for something to do in the meantime too man!

Re: Wifi doesn't work in Asus eee PC

Your driver is built into 3.0 http://cateee.net/lkddb/web-lkddb/R8187SE.html and your module is loading because wlan0 is showing up.

Chec you have your firmware right by trying to bring the link up with

# ip link set wlan0 up

Re: Wifi doesn't work in Asus eee PC

I'm running wicd on an acer 110 and had to resort to dhclient and that, together with wicd works really well. ath5k by the way.

This command returns:

RTNETLINK answers: Operation not permitted.

Upon sudoing nothing happens either. If the problem is the firmware, where can I find the correct packages to download?

Re: Wifi doesn't work in Asus eee PC

Have you tried explicitly loading the module?

modprobe rtl8187

https://wiki.archlinux.org/index.php/Rtl8187_wireless

and then check dmesg and run lspci again

lspci | grep inet
