Acer Aspire 5739G no WiFi/WLAN

[fosron]

Hey,

After installing Ubuntu 9.10 (wiht Wubi), i have no Wifi, neither LAN. Terminal shows that both of them is discovered by Ubuntu, but i can't connect. There's just loopback interface...
The button for WiFi doesn't work, so i can't enable it... But i think it's somewhere deeper...

WiFi - Intel 5100 ABG
LAN - Atheros AR8131

And it's weird, that 9.04 works just perfectly...

Some help would be really cool, because all of the info on the net is for <9.10 , and just doesn't work, or doesn't do any difference...

[fosron]

Bump. Still can't do anything about it...

[fosron]

sry for this , but i really need some help!

I had the same problem as you, and for me I did the following and now it works just fine!

sudo gedit /etc/default/grub

you'll find

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

change it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

update grub..

sudo update-grub

and restart

To Fosron :

Did the GRUB-trick from gecko1337 work for you? I tried installing Ubuntu 9.10 this weekend and ended up with the same problem that you encountered. I would like to try installing again, but would like to hear if this worked for you first?

I can vouch for the disabling acpi method. I (not surprisingly) had the same issue on my 5739g and it (not surprisingly) worked for me too.

The problem with disabling acpi is that, well, you don't have acpi anymore! You can't do things like get battery status, shut the machine off without actually pushing the button, etc. (Anyone reading this thread contemplating a 5739g: I love mine, don't let these issues hold you back! They'll be fixed soon enough I'm sure.)

Does anyone know any other way to fix this? I would sure like to have my acpi back...




Here's an apparently problematic snippet of my dmesg:

[   46.790662] iwlagn 0000:05:00.0: MAC is in deep sleep!.  CSR_GP_CNTRL = 0x0000008C

There are a bunch of other acpi-related messages before this but they fall off the buffer because there are about 1500 lines of the above "deep sleep" message. Any ideas?

i did what gecko1337 said to do... worked perfectly. only took a second... thanks for the help. would you happen to know how to fix the fingerprint scanner. I'm very new to ubuntu, and laptops for that matter.

I installed Ubuntu 9.10 yesterday and applied the acpi-fix! It worked right away and i got lan and wlan up and running. A bit sad that we loose the ability to see battery capasity, but as mitch_feaster said .. "They'll be fixed soon enough I'm sure."

A couple of things that also would be great to have working is the battery-saver button on the right top-side. Does anyone know how to configure this one?

would you happen to know how to fix the fingerprint scanner.

First of all, welcome to Ubuntu. Second, I got my fingerprint scanner using fingerprint GUI.

Installation directions:

1. Download the latest fingerprint GUI tarball (I'm using 0.12) (direct link).
   
2. Open a terminal and 'cd' to wherever you downloaded the file
   Example:
   

   cd Downloads

3. Extract the tarball and enter the directory
   

   tar xf fingerprintGUI-0.12.tar.gz
   cd fingerprint-0.12

4. Quickly install some dependencies
   

   sudo apt-get install libfprint0 libfakekey0

   Note: there's one more dependency, it's either libqca2-plugin-ossl, or libqca2. Try the first one first.
5. You're almost there! Read the developer's install directions for configuring PAM. They're in a file called "Install-step-by-step.pdf" in the fingerprint-0.12 directory and are fairly well written. The only thing I had to do differently was copy all my acquired fingerprint data (after Step 2 "Acquiring Fingerprints") to my root user's home directory:
   

   sudo cp -r ~/.fingerprints /root/

I think I covered everything I did... Let me know if works. Good luck!

Hello everyone,

I've been having the same problem with WiFi as everybody else on this thread and fixed it with the acpi=off solution.

As we all understand, disabling acpi is not a permanent solution as it disables some quite useful features of your laptop. Therefore I would like to know is there anything done about this issue? I mean, will Acer Aspire 5739G users be able to load their machines with Ubuntu 9.10 with acpi and WiFi together?

Thank you in advance,
Gintautas
