Mint 11 and WLAN

[herrrossi666]

Hi,

I have severe problems with the WLAN connection which is terribly slow. WLAN under Mint 11 is in total contrast to WLAN on Windows XP on the same machine.
The WLAN module I use is integrated in the Zotac IONITX T-E board and is very fast under XP and very slow under Mint 11. I think its an AzureWave WLAN module.
I had similar WLAN problems with my older computer and Linux and thought I could get rid of these (and other) problems by buying a new computer.

How can I get a fast connection under Mint 11? Is it a driver problem?

I would like to add that the Internet connection is sometimes also very slow even when I use a LAN cable. Opening a webpage or sending an email sometimes takes 20seconds which is inacceptable.

My provider and my router are super fast under Windows XP.

if you can provide a bit more information it will be easier for someone to provide help. Please post the output of these terminal commands.

Code: Select all

inxi -N

Code: Select all

sudo mintwifi

do the second will the ethernet cable is unplugged.

inxi -N gives:

With the Atherox AR9285 the driver should be the ath9k. Your output is just showing a, is that a copy/paste error or was that the actual output?

If that was the actual output, try going to
> Menu > Administration > Hardwire Drivers
and see if there is a wireless driver available, if so it would be ath9k. There probably will not be, I believe the atheros drivers are included in the linux kernel by default. In this thread viewtopic.php?f=90&t=75890&p=440631&hilit=9285#p440631 , AlbertP posted the following suggestion to run in terminal

Code: Select all

sudo echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

further down the thread he has a couple of additional suggestions.

If that does not work more suggestions can be found by searching this site for 9285. Also you may want to look into these two bug reports; there are possible solutions to be found at each.
Atheros AR9285 extremely slow & unstable on 11.04 https://bugs.launchpad.net/ubuntu/+sour ... bug/773154
driver ath9k is too slow or not responding https://bugs.launchpad.net/ubuntu/natty ... bug/735171

When I try your sudo echo command I get the following:

bash: /etc/modprobe.d/ath9k.conf: Permission denied

What's wrong here?

[dawgdoc]

What's wrong here?

First I would check to make sure the file exists. If it does check and see what the permissions are. You can do both at once with

Code: Select all

ls -l /etc/modprobe.d

[herrrossi666]

The command delivers the following result:

To answer the question above (regarding the inxi -N command: The output I posted above was not complete, find below the complete output:

Try as root.

Code: Select all

su

then password, and then

Code: Select all

echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

Reboot, and hopefully that'll fix it. Worked for me.
