[Bug 297965] Re: ath9k performances are unacceptable

 

Hi everyone, I too am having problems with ath9k stability as well as possibly speed.
I have tried testing this with 2.6.27-11 & 2.6.27-13 as well as the latest compat-wireless source for March 8th 2009 with my Atheros 5008 chipset (it's a Sparklan mPCIe card).

After about 10-15 seconds transfering a 1GB file, the connection stalls.
Prior to that the transfer rate is stated at around 8-9MB/s.

If anyone one would more detailed information about my system and configuration just let me know.
Other than that I guess this is just a "me too" comment. Speed seems fixed, but stability is not, nm-applet of course reports either unknown or 1mb/s.

My system is a Dell Latitude D531 AMD x2 1.9GHz, I'm running the 32bit
version of intrepid.

Haven't tried ndiswrapper yet, seems like a good workaround to get this
card at least going for now.

Bug description:
Tested with a Macbook Pro 2G (late 2006, Core 2 Duo + Atheros AR5008) and Intrepid.

I'm the lucky guy with a pretty good internet bandwith, around 10 Mb/s.

With Intrepid, the wifi works "out of the box" thanks to the ath9k driver, unfortunately, the price is poor performances, my connection speed can't get more than 1 Mb/s (instead of 10).

This bug report is not based on the NetworkManager reported speed, but based on some internet ADSL speed test web sites.

The last time I did the test with the following web site : http://www.degrouptest.com/test-debit.php, the reported performances were :
- Hardy + madwifi ng 20080301 -> 7700 kb/s
- Intrepid + ath9k -> 935 kb/s

I made this test with several other web sites at different times, and same result. Anyone can easily understand this is not acceptable.

I also did a real test case : watch the TV through the ADSL connection, with the Hardy configuration, no problem, with Intrepid it is just not possible.

I'm sorry because I won't be able to perform further tests, I need my Internet connection and as I couldn't be able to find a working fix, I downgraded my computer to Hardy...and I'm waiting for some progresses in Jaunty.

But I can answer questions.
