Atheros AR9285 low signal strentgh

Postby HansWurst » Wed Feb 10, 2010 17:49

Hi people!
I have an Asus EEEPC 1005PE with an integrated Atheros AR9285 wireless, here is my lspci -v:
Code: Select all
lspci  -v -s 02:00.0
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
        Subsystem: Device 1a3b:1089
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at f8000000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit-
        Capabilities: [60] Express Legacy Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Virtual Channel <?>
        Capabilities: [160] Device Serial Number 00-15-17-ff-ff-24-14-12
        Capabilities: [170] Power Budgeting <?>
        Kernel driver in use: ath9k
        Kernel modules: ath9k

The driver is loaded and wireles is working, but the signal strength is really low. Standing 5m away from the router (any router) gives me 30% of signal strength and many disconnections. Putting the computer right on top of the router gives me 90%. I use wicd. All the rest is working just fine, except for that signal strength thing. In Windows (dual boot) the problem does not occur. I found an Ubuntu forum where people had exactly the same Problem
http://ubuntuforums.org/showthread.php?t=1137780&page=3
The solved the Problem by installing a linux-backports-modules Ubuntu package.
What can I do to correct this Problem?
Here is my lspci

You just need to grab the latest build of the compat-wireless drivers. See this post:

other option is to install the 2.6.32-sabayon kernel. New driver for your card and can be done via entropy. Check kernel wiki how to do
