Reception is full but it often fails to connect to web pages. Kernel after updating: 3.0.0-15. Router Model is D-Link DIR-615. How can I find an appropriate Linux driver?

I'm running Ubuntu 11.10. The wireless card is a Broadcom 802.11a/b/g/n. Will be back with the results in a moment. – H3R3T1K Feb 12 '12 at 14:11
I don't know what a router channel number is. My other notebook works fine. I did download an additional wireless driver for it though. – H3R3T1K Feb 12 '12 at 14:33
ok - you have an atheros 9285. Please connect via a wired connection and use update-manager to update - your kernel should update to 3.0.0-15. Also please can you look at your router as per this question and see if reducing your router speed to 54MBs works for you:… – fossfreedom Feb 12 '12 at 16:27
Do you mean "WAN port speed"? It was set to 10/100Mbps. Other options were 100 and 10 Mbps. I set it to the latter. Didn't help. Powered router off and on again. Didn't help neither. – H3R3T1K Feb 12 '12 at 17:10
The driver youre looking for is called ath9k. you can ensure it's enabled by running lsmod | grep ath9k – Chris Wayne Feb 12 '12 at 17:52

Download and install the latest stable compat-wireless-3.3-rc1-2.tar.bz2

open up a terminal

cd Desktop or where_ever_you_downloaded_the_file

tar -xf compat-wireless-3.3.rc1-2.tar.bz2

cd compat-wireless-3.3.rc1-2


sudo make install

sudo make unload 


you could use the windows driver with ndiswrapper

install ndiswrapper

locate the .inf file

/sbin/modprobe ndiswrapper

One last ditch effort

Wireless (Atheros AR9285) works out of the box, but connection is flaky. To fix, open a terminal and type 'sudo apt-get install linux-backports-modules-karmic'

First suggestion did it, had to install "make" first though. – H3R3T1K Feb 21 '12 at 20:31
