Topic: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

Hi crunchbang users,

This is my story. I'll try to explain all details. 
My english is not so good at the moment but I think you will understand the main purpose of this thread.

This is my first post here in the crunchbang community.
A few months ago I was skeptical about change from windows to linux.
I was using Windows 7 ultimate but everybody knows that linux beat windows for sure.
In the past few weeks I learn al lot about linux and
>>>>  I'm very happy that I found crunchbang. <<<<<

First

I have an Asus K60iJ, I installed CB crunchbang-10-20111125-amd64 a few days ago, I'm impressed how fast and stable my laptop is now.
After the installation I test everything and worked flawlessly out of the box.

In windows the internet speed I get is 300kB/s .

In CB my internet speed start from 70kB/s stable but aftter a few minutes is only 26kB/s and after a few minutes from that, all my traffic stop suddenly, but I'm still connected to the internet.  I notice that behavior with diff servers location.

Can somebody point me in the right direction what could be happen?
Could be maybe the wireless drivers? ( I did'nt install any drivers because all works perfectly)
Do i need to install other drivers?
Or can I change something in the system to imporve the perfomance of my internet traffic?


I install vmware workstation and install windows 7 ultimate to see if  in windows 7 as a virtual guest happen the same issue, but not.  It works ok.  the internet speed get the maximum, the 300 kB/s.


I google and read a lot about this but the only thing I found is this (specific to my system)
http://forums.debian.net/viewtopic.php?f=30&t=72231

I did not have any installation issue at all. But I think that can be just tweaking the wireless setting a bit.

Second

In the site http://kmuto.jp/debian/hcl/

I run this code on terminal  'lspci -n' , copy and paste the result in the driver site and get this result.

I'll apprecciate if you read this and try to help me. 

thanks

Easy peasy. Open the file manager Thunar as root: 

gksudo thunar

Create a file named ath9k.conf in /etc/modprobe.d, just navigate to the directory, it's under File System. Open the file and paste this into it: 

options ath9k nohwcrypt=1

Save, reboot.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

It works!

Can you tell me what function does this line?   options ath9k nohwcrypt=1

It prevents my connection to be encrypted?

thanks

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

No, it's a known bug with some versions of the ath9k open source driver for your Atheros wireless card. The nohwcrypt option is low level driver stuff, nothing to do with encryption. No worries.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

After you have experienced the problem, and before you restart the network, run

dmesg| tail -n 80

in a terminal window.
This will display the last 80 lines of the 'kernel message buffer'
Check for error messages.
If you can not find any, increase the number.
If it is all gibberish to you, post the output in the forum.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

^do as the doctor perscribes. There's no documented problem with ath9k like the one you're describing, not that I know of anyway. Seems to be a DNS issue. We'll look into it. Post output of 

cat /etc/resolv.conf
apt-cache policy resolvconf

along the dmesg trace.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

Seems like you are running #! in a VM, which adds a level of complexity.
Is it possible to run it on its own, just to see if the errors are reproduced, and, if they are, for easier debugging.
While it is running on its own, and preferrably after you experienced the problem,
Post output of following commands:
(you can copy/paste the commands into a terminal window, press enter for the last command)

uname -a
lspci -knn | grep -i net -A2 
lsusb
egrep -v "^$|^#" /etc/network/interfaces
egrep -v "^$|^#" /etc/resolv.conf

I also suggest you try the bleeding edge compat-wireless.
See this page: http://linuxwireless.org/en/users/Drive … ireless%29
Let us know if you need more help with that.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

I'm running # on its own not in a vm.
Cruchbang is the primary and only OS i use.

I installed vmware and installed win7 virtual machine and I'm experienced error with this vm.
One error for example is that when I power on the vm it show me an error that the vm hard disk need to be defragemented, so I restart the vm  and it work great.

Do you think that the vm can cause this problem with #?

I think that the way I connect to the internet could cause this kind of problem.
This is the way  I connect to the internet. 

The internet conection I use is through a windows machine with virtual router enable.
With this software http://virtualrouter.codeplex.com/

The windwows machine connect to the internet with this device  Yota Jingle
http://www.yota.ru/en/devices/download/

Maybe an incompatibility?

This is the output.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

I am afraid it is a long standing bug in the ath9k driver, that has not been resolved yet, and that occurs under heavy load of the network interface.

This is the symptom:

[ 2827.074234] ath: Failed to stop TX DMA!

And a reboot is necessary to get wireless to work again.

Go to "search.gmane.org" and use the keywords  "ath: Failed to stop TX DMA" to see for yourself.

My advice is to use other hardware for your wireless needs until a solution is found, but, as I said, it is longstanding already.

If any one here knows of a better solution, please do not hesitate to step in.

If you poke the bear it is going to come after you.

Re: Asus K60iJx64 - Internet Connection speed slow and suddenly get stuck.

Thankyou Xaos52 for your time.

omg it is a long standing bug in the ath9k driver!!

I'm reading already all the threads about  Failed to stop TX DMA.
see if I find an alternative solution.

I'll try to use other wireless hardware.

I though another possibility.

I have a linksys router with a http://www.dd-wrt.com/site/index  software installed.

I want to connect that router to the windows machine that have the internet connection with Yota Jingle device and pass that connection to use the router as an ad-hoc network instead to use a virtual router.
So I will connect to the physical router.

Do you think is that possible?
Do you have an idea how to implement that?
