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.
