UNCLAIMED RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller [10ec:8185] (rev 20) not working on Acer Aspire T310 in Ubuntu 8.04.2

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following command (copy-paste the line below into a Terminal, press enter, then enter password when sudo asks for password, then press enter again)

cat /etc/lsb-release; sudo iwlist scanning; sudo lshw -C network; lspci -nn; lsusb; uname -a; dmesg | grep ound; dmesg | grep b43; iwconfig

Step 3: Please post results (copy/paste terminal output) on this thread

Step 4: Please also specify the exact model and make of your PC (if known) on this thread

Keep in mind that one or more of the following 5 basic components need to be configured correctly so that wireless can work correctly in Linux:

Wireless configuration in the BIOS, hardware wireless switch setting, active wireless driver version, the firmware for the wireless chipset (stored as a file in Linux), and the configuration of the wireless parameters in wicd or NetworkManager (SSID broadcast settings, encryption settings, name of wireless interface stored in wicd, the chosen channel for wireless transmission, ...) .

Regards,

Mark

my computer is a acer aspire t310. i will hook it up to a wired connection soon and paste what the terminal gives me

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=8.04

Hi,

Please read the links below:

It seems Ubuntu 8.04 will not support this wireless chipset out-of-the-box (due to a regression??).

Easiest solution should be to install the 32-bit version of Ubuntu 9.04 from a LiveCD session.

If the wireless does not work during the Ubuntu 9.04 LiveCD session, then try the Ubuntu 8.10 LiveCD as a last resort option.

Hi,

The following link confirms my suspicions:

http://cateee.net/lkddb/web-lkddb/index_r.html

You need the following kernel configuration enabled in the kernel:

CONFIG_RTL8180 (from release 2.6.25)

But this native Linux kernel driver RTL8180 is only available in kernels 2.6.25 or higher.

But you are using kernel 2.6.24 which is too old.

So the easiest solution should still be to install the 32-bit version of Ubuntu 9.04 from a LiveCD session.

Regards,

Mark
