Description Brian Jedsen 2008-05-28 14:57:17 UTC
Description of problem:
The ath5k driver, though most awesome, has a funky way of setting the rate of
the card. When set to auto, it will drop the connection rate to 1MB every second
or so. When the rate is manually set with iwconfig, the connection is dropped
after about 10 seconds.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start large transfer
2. Set rate with iwconfing (iwconfig wlan0 rate 11M)
3. Observe the connection fail
Actual results:
Either the rate is set to 1M every second or so, or, if the rate is manually
set, the connection drops.

Expected results:
Free, fast and easy wireless (almost there!).

Additional info:
dmesg reports this: "ath5k phy0: noise floor calibration timeout" every minute
or so.

Comment 2 Brian Jedsen 2008-05-28 15:11:38 UTC

Thanks for the quick response.

Comment 3 John W. Linville 2008-06-23 19:09:27 UTC
Is this still happening with -55.fc9?

Comment 5 Brian Jedsen 2008-07-01 01:50:22 UTC
I'm not having this problem with -55 any longer. I can set the rate to 11MB with
iwconfig and it works without timing out.
